Data release accompanying Quantitative Mineral Resource Assessment of Lithium Pegmatite Deposits in the Southern Appalachian Orogen Data release accompanying Quantitative Mineral Resource Assessment of Lithium Pegmatite Deposits in the Southern Appalachian Orogen
A mineral resource assessment for lithium was carried out by the U.S. Geological Survey (USGS) for the southern Appalachian region, between latitudes 31N and 40N and longitudes 75W and 89W, in the following states: Maryland, Virginia, North Carolina, South Carolina, Tennessee, Georgia, Alabama. This study (Rosera and others, in press) integrates data from several sources, including...
Data release accompanying quantitative mineral resource assessment of lithium pegmatite deposits in the Northern Appalachian Orogen, USA Data release accompanying quantitative mineral resource assessment of lithium pegmatite deposits in the Northern Appalachian Orogen, USA
The area of study is restricted to the northern Appalachian region between latitudes 38N and 48N and longitudes 66W and 77W in the U.S. states of Maine, New Hampshire, Vermont, New York, Massachusetts, Connecticut, Rhode Island, Pennsylvania, and Delaware. This study (Wintzer and others, 2025) integrates data from several sources, including geologic, geochemical, geophysical, watershed...
Dataset for mineral resource inventory of North Dakota Dataset for mineral resource inventory of North Dakota
This data release contains the geospatial resources that were used by the USGS to compile the mineral resource inventory for the state of North Dakota, developed by the Mineral Resource Program (MRP) staff of the U.S. Geological Survey (USGS) at the request of the Bureau of Land Management (BLM). The mineral resources inventory was published as a USGS open-file report and can be accessed...
Thin section images of hand samples from the Crocodile Lake and Cucumber Lake Intrusions, Duluth Complex, Minnesota Thin section images of hand samples from the Crocodile Lake and Cucumber Lake Intrusions, Duluth Complex, Minnesota
This dataset includes photographic images of thin sections created from hand samples collected from the Crocodile Lake and Cucumber Lake Intrusions, Duluth Complex, Minnesota, along with a shapefile representing the locations of the samples. The samples were collected in order to define copper-nickel-platinum-group element resources associated with the Crocodile Lake and Cucumber Lake...
Thin section images of drill core and hand samples from the South Kawishiwi Intrusion, Duluth Complex, Minnesota Thin section images of drill core and hand samples from the South Kawishiwi Intrusion, Duluth Complex, Minnesota
This dataset includes photographic images of thin sections created from hand samples and drill core sourced from the South Kawishiwi Intrusion, Duluth Complex, Minnesota, along with two shapefiles representing the locations of the samples and drill hole collars. The samples were collected and core was drilled in order to define copper-nickel-platinum-group element resources associated...
Thin section images of drill core and hand samples from the Stillwater Mine area, Stillwater Complex, Montana Thin section images of drill core and hand samples from the Stillwater Mine area, Stillwater Complex, Montana
This dataset includes photographic images of thin sections created from hand samples and drill core from the Stillwater Complex, Montana, along with a shapefile representing the locations of the underground samples and drill hole collars. The samples were collected and core was drilled in order to define platinum-group element resources associated with the J-M Reef at the Stillwater Mine...
Quantitative mineral resource assessment of lithium pegmatite deposits in the southern Appalachian orogen Quantitative mineral resource assessment of lithium pegmatite deposits in the southern Appalachian orogen
The first quantitative mineral resource assessment for undiscovered lithium pegmatite deposits in the southern Appalachian region of the United States was conducted. Permissive tracts for lithium pegmatite deposits were delineated by integrating lithological, tectonic, geochemical, geophysical and mineral occurrence data. Lithium pegmatite prospectivity of the tracts was ranked with...

Rock sample photogrammetry Rock sample photogrammetry
This step-by-step protocol describes the photogrammetry process used by the U.S. Geological Survey Spokane Imaging Lab (SPIMG) lab to create 3D models of geologic samples. Steps related to photographing small objects are applicable to photogrammetry in general, however, SPIMG-specific steps involving lab hardware and software may not be.
