Quarterly Science Newsletter Frontline Geoscience within the Geology, Energy & Minerals (GEM) Science Center, Reston, Virginia Quarters 2 & 3, 2023 Double Issue: Issues #10 & #11 Center Director Note Welcome to the first double issue of our USGS (U.S. Geological Survey) Geology, Energy & Minerals Science Center (GEM or GEMSC) quarterly newsletter. Stakeholder engagement is a crucial piece of disseminating our science, so thank you for taking the time to read through what we have been working on. I always think of engagement as a two-way street; I encourage you to reach out if you are interested in starting a dialog regarding research collaborations, job opportunities, or newsletter content. As you may have heard, there is a push for the Federal workforce in the National Capital Region (greater D.C. area) to report in-person more frequently. Because of the collaborative, interdisciplinary nature of our work and our extensive set of laboratories (20+), we are often in the office already. Utilizing telework and a "hybrid" model has allowed us to maintain a high level of impact while considering the future of science and collaboration at GEM. In the past two quarters, we were represented at several conferences, including Goldschmidt, the Applied and Environmental Microbiology Gordon Research Conference, and the European Geophysical Union General Assembly. We have released 20 publications and 18 data releases. We onboarded 17 new employees and contractors and are currently advertising 2 open positions (see page 10). To explore more about what we do, please visit our USGS GEMSC website. If you know anyone who may be interested in receiving this newsletter, or if you would like to adjust your subscription status, please refer to the online subscription form. As always, please reach out to our Center Director directly (troberts-ashby@usgs.gov) with any comments, questions, or ideas for collaboration. ~ Evan Bargnesi, Associate Science Center Director of the GEMSC, on behalf of Tina Roberts-Ashby Ph.D., Center Director of the GEMSC Science Spotlight Earth Mapping Resources Initiative (Earth MRI) The USGS launched the Earth Mapping Resources Initiative (Earth MRI) to modernize the surface and subsurface geologic mapping of the United States, with a focus on identifying areas that may have the potential to contain critical mineral resources. Using readily available geologic, geophysical, geochemical, and mineral deposit data, teams of USGS scientists worked with representatives of State geological surveys to outline focus areas that contain evidence of key features for one or more mineral systems. The newly released USGS Fact Sheet (Hammarstrom and others, 2023) is the first national map of focus areas classified by mineral systems based on the data compiled in Dicken and others (2022). In addition, information on mineral deposits that produced critical minerals in the past and/or have identified critical mineral resources was compiled from USGS databases, industry reports, and literature sources. Deposits are classified by mineral system, deposit type and focus area. More than 200 deposits have documented critical mineral resources that have not been mined. (Begin Page 2) Science Spotlight (Continued) North American Helium Conference GEMSC Research Geologist Sean Brennan was one of the organizers for this Rocky Mountain Association of Geologists meeting, which had over 40 technical presentations on topics such as exploration methods, plays, reservoir characterizations and case studies. Technical sessions featured topics including helium mid-stream, markets, regulation, and financing. In addition, Dr. Brennan gave the first presentation at the meeting, which covered the USGS helium resources assessment. GEMSC Research Geologists Matt Merrill and William Craddock gave talks related to the production and exploration of helium natural resources from lands under Federal, State, and private mineral ownership. More info on the meeting's importance can be seen in the American Association of Petroleum Geologists (AAPG) Explorer and more on the meeting can be found HERE. Geoheritage Workshop II The USGS Geoheritage Sites of the Nation Project is funded by the USGS National Cooperative Geologic Mapping Program (NCGMP) and was kicked off in Fiscal Year (FY) 2023 after a geoheritage pilot project in FY2022. This project, led by GEMSC Physical Scientist Christina DeVera, hosted the USGS Geoheritage Workshop II in April 2023 to gather feedback from other Federal agencies, State geological surveys, academia, non-profit organizations, and Tribal communities and collaboratively develop an initial methodology outlining the data standards for geoheritage site selection based on scientific, educational, cultural, economic, and aesthetic values of unique geological features. The geoheritage geospatial product (GGP) will be incorporated into the USGS U.S. GeoFramework Initiative (USGI) to provide an educational and outreach tool to raise awareness of significant geologic sites, communicate the role of geology in our natural heritage, and make geologic mapping and geoscience topics more accessible and relevant to the public. If you are interested in learning more about the project, please contact Christina DeVera at cdevera@usgs.gov. 2023 Goldschmidt Conference in Lyon, France In mid-July, six GEMSC scientists traveled to Lyon, France, for the Goldschmidt conference. Isabelle Cozzarelli and Bonnie McDevitt co-convened a session titled: “Anthropogenic contaminants in the environment: geochemical fate, transport, modelling, and novel remediation approaches”. Isabelle Cozzarelli gave a talk on the application of waste materials on farmed lands from agriculture, livestock and the oil and gas industries. Bonnie McDevitt discussed the impact of radium in drainage precipitates on remediation of mine lands in Appalachia. Bryan Killingsworth delivered a presentation on the dynamics of sulfide oxidation and its implications for understanding and tracing pyrite oxidation mechanisms via oxygen isotope techniques. Rebecca Stokes chaired a session titled "Critical raw materials for the renewable energy revolution" and discussed her work on strain-induced graphitization. Sarah Jane White chaired a session titled "Bioavailability, toxicity, and environmental behavior of trace metals, and their mechanistic pathways and utility in disease diagnostics" and presented her Environmental Health Program work on prioritizing critical minerals for study based on data availability and gaps in our understanding of each element’s geochemistry, bioavailability, and toxicity. Nadine Piatak gave a talk on on the enrichment of germanium and other trace elements in sphalerites from Mississippi Valley-type (MVT) deposits in the United States, and their potential for recovery as byproducts. Kathryn Hobart presented on a portion of her postdoctoral research on critical mineral concentrations in tailings from volcanogenic massive sulfide deposits, focusing on trace cobalt in pyrite and pyrrhotite. Conference information can be found HERE. (Begin Page 3) Science Spotlight (Continued) Field Work to Retrieve Research Cores in the North Slope of Alaska In June and July, staff from the Alaska Basins and Petroleum Systems Project conducted field work on the North Slope of Alaska. The major focus of this year’s effort was the retrieval of two research cores. This was a joint effort between the USGS Energy Resources Program, USGS Research Drilling Program, and the State of Alaska Division of Geological & Geophysical Surveys (DGGS). The first of these cores (USGS/DGGS Slope Mountain #1) targeted the Cretaceous Nanushuk Formation and was sited behind the Slope Mountain outcrop—one of the best exposures of the formation in the region. The Nanushuk Formation hosts several of the recent, large oil discoveries in this province (the largest U.S. onshore discoveries in >30 years) and remains a focus of active exploration. The core will help to constrain reservoir properties in recent discoveries and inform ongoing exploration efforts. The second core (USGS/DGGS Landslide #3) targeted the Cretaceous Seabee Formation. The Seabee Formation is not only an important petroleum source rock in the region, but also contains a stratigraphic record of a recent greenhouse climate event. Drilling activities will resume in the summer of 2024. After coring activities wound down, a team of USGS scientists spent an additional week working mostly in Arctic National Wildlife Refuge. The objectives of this work included characterization of a) Cretaceous/Paleogene strata, with applications ranging from petroleum reservoir prediction to paleoclimate reconstruction, and b) the active tectonics of the Arctic Alaska province, which are a key to understanding the structural and geodynamic history of the province at longer time scales pertinent to regional petroleum systems. Publications on South Texas Coastal Plain Roll-front Uranium Deposits GEMSC scientist, Bernard Hubbard, recently published two lead-authored papers and a data release describing work on critical and industrial minerals related to sandstone-hosted uranium deposits in the south Texas Coastal Plain, also known as roll-front uranium deposits. Between 1955 and 2013, about 8% of U.S. production of uranium was extracted from an estimated 92 sandstone-hosted (i.e., roll-front uranium) mines in Karnes, Live Oak and Atascosa Counties, Texas. Prior to the use of in situ recovery methods, open-pit mine extraction left numerous waste piles and pit craters, some filled with water as lake features on the landscape. Today, some of the host rocks formerly mined for uranium (e.g., Jackson Group) also host bentonite and zeolite deposits which are still mined today in neighboring counties. One of the two papers in the journal MDPI-Minerals describes remote sensing methods developed for inventorying uranium mines and mine waste and determining their reclamation status based on land-use and land-cover patterns revealed from image interpretation. The second paper in press in the Journal of Geochemical Exploration summarizes the spectral characteristics of these rocks including abundances of critical ore minerals (e.g., coffinite) and industrial minerals (e.g., Ca-bentonite, Na-bentonite, and zeolites). A separate USGS data release provides access to original spectral measurements conducted on representative Texas Bureau of Economic Geology cores. Critical Mineral Assessment with AI-Support (CriticalMAAS) Program In August, the USGS, Defense Advanced Research Projects Agency (DARPA), and Advanced Research Projects Agency–Energy (ARPA-E) teamed up to launch the Critical Mineral Assessment with AI-Support (CriticalMAAS) program. Participants from across the Federal government, academic institutions, and private research sector met at the National Conservation Training Center in Shepherdstown, West Virginia to kick off the 12-month effort geared toward accelerating critical mineral resource assessment workflows. Novel machine learning applications to geoscientific problems include automated georeferencing and feature extraction from geologic maps, extracting geospatial and descriptive information for mineral occurrences using large language models to aid in their classification, and multi-scale data fusion across geological, geochemical, and geophysical modalities to enhance predictive mapping. These tools and techniques under development promise to help the USGS achieve its mission objectives related to mapping critical mineral resources in the United States, make legacy data more useful and accessible, and inform decisions on securing critical mineral supply chains for the United States. (Begin Page 4) Science Spotlight (Continued) Assessment of Rare Earth Elements and Critical Minerals in U.S. Gulf Coast GEMSC Research Geologist Peter Warwick released a publication as part of cooperative work with the University of Texas at Austin, Bureau of Economic Geology on the project "Assessment of Rare Earth Elements and Critical Minerals in U.S. Gulf Coast," funded by the Department of Energy, National Energy Technology Laboratory, Carbon Ore, Rare Earth and Critical Minerals (CORE-CM) Initiative for U.S. Basins. Coal is increasingly evaluated as a source of rare earth elements (REEs) in the United States to address the the Nation's over-reliance on imported REEs. The objective of this study was to assess the distribution of REEs in lignites from selected mining areas in the Texas Gulf Coastal Plain region. This publication presents new REE and critical mineral analytical data obtained from thirty lignite and rock samples previously collected by the USGS. REEs are essential in the manufacture of electronics, magnets, catalysts, optics, ceramics, and numerous other products necessary for the functioning of modern society. Policy makers and the mineral production industry may be interested in the results contained in this publication. Full article can be found HERE. Gulf Coast Wells and Logs Database The United States Gulf Coast Basin Curated Wells and Logs Database (CWLDB) is an online repository with stratigraphic information for petroleum wells in the United States portion of the onshore Gulf of Mexico Basin. It provides several of the following attributes: a) deep penetrations (generally, total depth of 10,000 feet or more), b) high-quality and diverse geophysical well-log suites, c) lithostratigraphic logs, d) biostratigraphic units (biozones) and reports, and/or e) core or cuttings samples. This data release expands the scope of USGS public-facing petroleum and subsurface geologic and geophysical data offerings. This database is a work in progress and is expected to be updated with additional wells as new interpretations are generated. Therefore, the spatial, temporal, and depth ranges are set to account for well locations throughout the Gulf of Mexico Basin. Additional entity and attribute columns are included to allow for future data types and interpretations. The dataseet is being compiled by GEMSC Research Geologists Marc Buursink and William Craddock. See the data release HERE. Bemidji Fieldwork Biologist Bridgette Polite and Research Microbiologist Denise Akob joined USGS Water Mission Area, Upper Midwest Water Science Center (WSC), California WSC, and university colleagues on a successful sampling campaign in June to collect groundwater samples from the National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota, USA. The site was contaminated by a crude oil pipeline rupture in 1979 and has been a long-term USGS study site since 1983. Over the past ~40 years, the research at the site has improved our understanding of the mobilization, attenuation, transport, fate, potential health effects, and remediation of petroleum hydrocarbons in the subsurface. The main goals of the sampling were to 1) monitor fate and transport of hydrocarbons, degradation byproducts, and trace metals in the aquifer; 2) understand microbial processes contributing to contaminant degradation; and 3) expand upon historical water quality data sets that document evolution of the contaminant plume. The team collected water samples from 24 groundwater wells for biogeochemical analyses. The samples are currently being analyzed to help understand processes controlling hydrocarbon natural attenuation.

(Begin Page 5) Science Spotlight (Continued) Arctic Extended Continental Shelf International Workshop Delegations from four Arctic nations (Canada, Denmark, Norway, and USA; Russia has been excluded) met in Stavanger, Norway in April of 2023. GEMSC Senior Research Geologist David Houseknecht attended this review of pertinent data and national submissions to the United Nations Law of the Sea, Extended Continental Shelf program, Arctic region. The U.S. delegation included Arctic policy and technical specialists from the State Department, National Oceanic and Atmospheric Administration, USGS, and universities. Houseknecht presented “North Chukchi Basin and Southern Chukchi Borderland: Geology, Tectonic Origin, and Direct Hydrocarbon Indicators in Seismic Data.” This presentation pertains to the region of the northernmost maritime boundary between the U.S. and Russia as well as the region farther north, beyond the U.S. and Russia Exclusive Economic Zones. This work has clear and direct implications to Extended Continental Shelf claims by Arctic Nations and represents a significant contribution to understanding the geology and tectonic origin of a large region within the Arctic Ocean. Results also will contribute to the Energy Resources Program – National and Global Assessment project by providing the framework for future assessments in the area.

(Begin Page 9) Scientist Profile ~ Dan Haybe I have been extremely fortunate to have worked at the USGS for the past 43 years. While I was very happy to join the Survey in 1980, little did I appreciate how lucky I was to be hired by Phil Bethke and Paul Barton. They were remarkable scientists, wonderful mentors, and most importantly, terrific human beings. Working with them was the best education I could ever hope for. They taught me, and scores of other scientists (including Nora Foley, Bob Seal, Geoff Plumlee, and Tom Casadevall), the value of collaborative science. They never argued but were not afraid to disagree, probe, and challenge each other’s thinking (or anyone else’s). Together they were amazingly creative and productive - I came to see them as the “Lennon and McCartney” of Economic Geology. My interest in Geology began with my first class at the College of Wooster – Geology 101 at 8:00 a.m.! I loved the prospect of combining science and working outside. I was drawn to ore deposits and for my senior thesis used a 12 ft3 tank to model bedded sulfide deposition in a sabkha environment. As fate would have it, I first met Phil when my advisor brought him to the dusty Geology Department basement to view my experiment (Phil had brought one of his sons for a college visit). Next, I headed to grad school at Penn State, where I was fortunate to get Hu Barnes for my advisor; he was a giant in the field of Economic Geology – the editor of Geochemistry of Hydrothermal Ore Deposits. He required his students to subscribe to Economic Geology, and fortuitously, the first paper in the first issue I received was Barton et al.’s seminal paper on the Creede epithermal deposit. As a green graduate student struggling at a high-powered university, I was also very fortunate to be mentored by Don Rimstidt (a postdoc at that time). I credit him with helping turn my research on the Salton Sea geothermal system into an acceptable Master’s thesis. In 1978, Exxon Production Research Co. hired me to develop computer block models to estimate ore reserves (Exxon owned several prospects at that time). In those early days of mainframe computers, “big jobs” needing 256K memory had to run overnight! While I enjoyed my job, I decided that the USGS would be a better fit. Leaving Houston was an added benefit. At the USGS, I joined the “Environment of Ore Deposition” (a.k.a., Creede) project to conduct research on epithermal deposits. I analyzed fluid inclusions to better understand fluid movement and ore deposition. A few years later with Phil’s encouragement, I applied for and was accepted into the long-term graduate training program to study numerical flow modeling at the University of Illinois with Craig Bethke (Phil’s son). As part of my Ph.D. thesis, I developed the USGS computer program, HYDROTHERM, to simulate high temperature/pressure, two-phase fluid flow in hydrothermal systems. In the 1990s, my journey took some unexpected and interesting turns. I received a USGS Gilbert Fellowship to spend a year in New Zealand working on geothermal and volcanic systems. Upon my return, I was transferred to the Eastern Energy Resources Science Center (EERSC) to begin modeling basin-scale evolution and fluid migration as part of oil and gas assessments. After 25 years of happily working as a project scientist, I was encouraged to take on a leadership role. I began that part of my journey as the Associate Center Director for EERSC. Being a “people-person,” I found that I enjoyed the day-to-day interactions that leadership requires. In 2008, I was selected as the Center Director for the Eastern Mineral and Environmental Resources Science Center, and a couple of years later was “asked” to also take on the directorship of EERSC (note: no doubling of salary). In 2014-15, I also served as the Acting Associate Director for the Energy & Minerals and the Environmental Health Mission Areas. Three years ago, I stepped down as Center Director. I currently work half-time as a senior advisor for the Core Science Systems Mission Area and half-time on NCGMP and Minerals projects. Throughout my career, I have been blessed to work alongside gifted and dedicated people, to conduct research on interesting projects, to lead a terrific group of scientists, and most importantly, to have a wonderful wife and family—6 children (including 2 adopted) and 4 grandchildren so far! (Begin Page 10) Center Achievements & Recognition 10-year Anniversary of the Landmark Publication, ‘Geochemical and Mineralogical Maps, with Interpretation, for Soils of the Conterminous United States’ Prior to 2013 knowledge about the concentration and spatial distribution of naturally occurring chemical elements in soils of the conterminous United States was remarkably limited. This began to change in 2007 when the USGS initiated a low-density (1 site per 1600 km2) geochemical and mineralogical soil survey across the lower 48 States. Three soil samples were collected from different depths from the nearly 5,000 randomly selected sites. The < 2 mm fraction of each sample was analyzed for a suite of 45 major and trace elements and as well as major mineralogical components. Sampling took 3 years to complete, and chemical and mineralogical analyses were finally completed in 2013, with all data released in USGS Data Series 801. Now, 10 years later, the report and its accompanying data have been cited nearly 400 times by a wide variety of national and international researchers across an amazing array of topics from environmental and human health to forensic geology to mineral exploration. The USGS also created a series of derivative maps showing the spatial distribution of each element or mineral with an accompanying interpretive section—these maps often show up in papers and presentations and have been an excellent avenue into the larger geochemical and mineralogical dataset.
