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 Additional radiometric dates were compiled from both published and unpublished sources.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...

Minnesota Geological Survey, in cooperation with industry, sampled the State of Minnesota and adjacent regions for till geochemistry and indicator minerals at a 30-km spacing during summer 2004. Within target cells, each a quarter-degree latitude by a half-degree longitude, till from between about 1 and 2 m depth was sampled by filling a 15 liter plastic pail. At a few sites, vertical profiles were collected. In addition, three transects to the north were sampled, to help identify sediments derived by long-distance glacial transport, to obtain reference samples from the Thompson nickel belt, and also to extend sampling to the limit of Hudson Bay-derived carbonate-bearing sediments, to permit comparison to Minnesota...

All sediment samples from auger holes, outcrops, and cores are processed to determine texture. The 1-2 mm coarse sand fraction is packaged separately, and about half of these fractions are categorized lithologically by a glacial geologist. The data are recorded on paper data sheets and in a database.

Hand specimens of rocks collected as a part of field work conducted primarily by present and former WGNHS staff members. Samples date from the early 20th century to the 1990s and were collected throughout the state. Many of the samples are described in the historical field notebook collection, and relationships between the samples and the field notebooks have been established and captured in identifiers. Locations for samples were taken from field notes, maps, and accession lists. There are approximately 5,700 hand samples in this collection.

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,...

In 2008, Virginia Department of Energy received by donation from the University of Virginia (UVA) a large collection of rock, mineral, and fossil specimens that was at risk of imminent disposal or dispersal due to the lack of adequate storage facilities. The collection includes many valuable and irreplaceable geologic specimens collected in Virginia by UVA students, faculty, and geoscientists from the early Virginia Geological Survey. Parts of the collection were at one time displayed in the Lewis Brooks Hall of Natural Science, which opened in 1877. Following the closure of the UVA Department of Geology in the 1960s, the collection was moved to various warehouse storage areas, where it was largely forgotten and...
