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 Additional radiometric dates were compiled from both published and unpublished sources.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 is comprised of oil- and gas-related well cores and cuttings from wells drilled to either test for the presence of liquid or gas fossil fuels, examine subsurface stratigraphy and structures, or to produce liquid or gas fossil fuels. All well data in the Alaska Geologic Materials Center (GMC) database represents both exploration and production wells. Core has been donated by oil and gas exploration companies as well as state and federal agencies. This oil and gas related sample collection includes core, core chip, side wall core, cuttings, and unwashed cutting samples as well as oil and gas related surface and shot-hole samples.

This sample collection consists of a 1997 donation from the Shell Oil Company to the Alaska Geological Materials Center. It contains approximately 68,000 samples of following types: dart (short seafloor cores), seismic shothole, outcrop, and megafossils. 80% of the collection are outcrop samples. 5 percent of the collection has been inventoried with specific locations. Most of the collection is in good shape though many megafossil sample bags need to be replaced. The remainder of the collection will be inventoried in a future data preservation project
This collection is comprised of digital, slide and print photographs taken during energy resource related field projects from 1970-2020. The majority of the individual items associated with this collection are field photos taken by Charles (Gil) Mull and Rocky Reifenstuhl. These photos document field sites, geologic features, landscapes and landforms from the various areas of Alaska. There are approximately 43,000 photos and slides that still need to be culled, documented and archived. 98% of the photos are in digital format and need to be manually matched with their locations from geologists' field notes. The remaining 2% are slide and print format that need the same attention but are in fair to good condition.
