This collection includes field notes, interpretive geologic field maps, field station location maps, and other project materials, many of which are unpublished and archived by the Alaska Division of Geological and Geophysical Surveys. These materials have not been reviewed for accuracy, consistency, or completeness. The collection may contain data and documents pertaining to all related fields of geology, including oil and gas, geologic engineering, minerals industry, scientific data, and agency archives.
This collection is comprised of legacy DGGS geologic maps that have been converted to the single-map USGS Geologic Map Schema (GeMS; formerly known as NCGMP09). Initial conversions will be conducted on maps in areas with critical mineral potential, benefiting DGGS and USGS critical mineral studies in Alaska. Future additions to this collection will include both converted geologic maps, and new geologic maps created using the GeMS schema.

The Alaska Division of Geological and Geophysical Surveys (DGGS) surface sample collection consists mostly of hand samples collected during projects involving DGGS geologists, but also includes pulps and residues. The accuracy of the sample metadata differs based on the time frame of the project that originated the samples. The DGGS projects fall in two categories: (1) legacy projects where sample locality information was not recorded systematically in either a physical or digital format and (2) recent and current projects where sample locality information has been recorded in digital databases. This collection consists of 123,808 rock samples as of 2020, though not all are accessible to the public or have location...

This collection consists of samples with age data and associated information for available radiometric dates for rocks and minerals in Alaska. The sample records and their associated publications were loaded into the Alaska Division of Geological and Geophysical Surveys division-wide database. A legacy Microsoft Access database exists that includes dates for all available U-Pb, K-Ar, 40Ar/39Ar, and Rb-Sr data for Alaska through 2007. Previous compilations by Wilson and others (1990) and U.S. Geological Survey (1999) provided the initial source of age data. Additional radiometric dates were compiled from both published and unpublished sources. This legacy project added essential basic supporting information that...

This collection represents field station locations digitized from legacy field station maps, geologic interpretive maps, analytical reports and field notes. The points were on-screen digitized from scanned, georegistered station location maps using georegistration best practices and ESRI ArcMap software or digitized via data entry from field notes and reports. Most records indicate the geologist, field project and year collected based on the information available about the archived item or from interviews with current and former DGGS geologists and database research.

This collection as a whole includes diamond drill core from hardrock/lode mineral prospects that have been donated to the Alaska Geologic Materials Center (GMC) by private entities or that have been recovered from properties during reclamation of historic mine and exploration sites by the U.S. Bureau of Land Management. The core is stored in waxed cardboard or plastic boxes. Mineralized portions, and in some cases the entire the core, has been split and sampled. Some core may have been quartered and sampled, or entirely consumed. The condition and completeness of the core varies widely. The individual records listed are comprised of diamond drill core from identified mineral prospects; it may include some coal prospects,...

This collection consists of raw sample analyses of whole rock major oxide with minor element analyses on rock, soil, or stream sediments samples, as well as trace metal analyses. In general, the analyses include only those samples collected from projects involving Alaska Division of Geological & Geophysical Surveys (DGGS) geologists or that appear in DGGS publications. However, many U.S. Bureau Mines and Bureau of Land Management publications and a small percentage of U.S. Geological Survey publications are also included. The database is continually updated as more data is collected and formatted for loading.
This collection represents the DGGS Alaska mineral resources and exploration database, with a focus on critical minerals. The Alaska Minerals Database (AMDB) provides access to information on all "significant" occurrences and properties in Alaska, including any known references to by-product critical minerals. This collection helps agencies and industry identify and prioritize regions and Alaska deposit models prospective for a variety of commodities, including critical minerals. The collection includes XXX records of Alaska mines, development and exploration projects, and significant mineral prospects.

The Geologic Materials Center (GMC) Data Report collection contains analytical and interpretive data resulting from testing by third parties on material donated or borrowed from sample materials housed at the Alaska Geologic Materials Center. These reports are produced by the third party agency or company that conducted the sampling and analysis, and in some cases, interpreted results. The reports have not undergone technical peer review and should not be used or cited as reviewed data.
