Geoscientific collections managed by Alaska Division of Geological and Geophysical Surveys (DGGS) are aggregated in the National Digital Catalog to enhance discovery and use of valuable samples and data for further scientific research. Contact information and material access instructions are provided for the individual collections.

Thin sections prepared primarily in the course of research conducted by geologists of the Wisconsin Geological Survey. There appears to be a set of USGS-related thin sections, as well, but these are not evaluated at this time. Thin sections are tied to field notebooks, which are being reviewed as time allows. Certain physical collections have been located, but their geographic location is uncertain until the field notebooks can be tied to the actual thin section. We must tie physical materials to field notebooks in order to develop geographic coordinates for specific thin sections. Work to date has identified locations of physical items and is currently focused on assessing the notebooks themselves. There are 1,700...

Cores represent over 2,000 individual core sites drilled across the State of Wisconsin; stored in over 56,000 (mainly cardboard) boxes; representing approximately 650,000 linear feet of the subsurface. The Flambeau Core subcollection is approximately 3 percent of the collection of rock cores from Wisconsin. Documentation for the Wisconsin core collection is routinely updated, as information becomes available.

This map set contains unpublished maps, cross- sections, and related information archived by the State Geological and Natural History Survey of Connecticut as part of the Survey Library Collection. These materials have not been reviewed for accuracy, consistency, or completeness. For many geographic areas, more current information exists, either in published or unpublished form. For the most part, these materials were developed under research and mapping agreements between the State Geological Survey and individual scientists, academic institutions, or graduate students. Some of these materials have been received by the State Geological Survey as donations. The veracity of the information contained within...

The Arkansas Geological Survey (AGS) is the curator for the Norman F. Williams Well Sample Library and maintains well cuttings and core samples as a permanent record of rock strata that have been penetrated by wells drilled in Arkansas. Driller logs housed at the Survey contain the down hole information about the geology in the state. Each log gives the depth in feet along with the discription of material being drilled and the depth it accurs. The logs cover wells drilled in the early 1900’s to 1950’s and dispersed throughout the state giving statewide subsurface information.

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 currently contains approximately 24,000 oil- and gas- related surface samples, which is a subset of the 507,000 surface samples housed at the Alaska Geologic Materials Center. The Amoco Heritage Collection was donated by Amoco-BP in 2002 and contains samples from fieldwork conducted from 1960-1990 in high energy-resource-potential areas of Alaska.

The Core Research Center (CRC) was established in 1974 by the U.S. Geological Survey (USGS) to preserve valuable rock cores for use by scientists and educators from government, industry, and academia. The cylindrical sections of rock are permanently stored and available for examination and testing at the core storage and research facility in Denver, Colorado. The CRC is currently one of the largest and most heavily used public core repositories in the United States. The CRC encourages use of its facility by all interested parties. Tours of the facility are available by appointment.

Most projects conducted by the MWRA have attached to them a geotechnical report and accompanying environmental information. There are also eighteen marine drilling reports on work in the Boston Harbor, as well as, two hardbound copies on the Geology of the Waschusett Reservoir Area. All reports are stored in the library at the main facility in Chelsea; however, not all project managers turn over reports to the librarian for storage. Most projects conducted by the MWRA, related to the construction of water and sewer lines, have attached with them, a geotechnical report and accompanying environmental information. Other paper reports include: eighteen marine drilling reports from work in Boston Harbor; as well as two...

The Core Research Center (CRC) was established in 1974 by the USGS to preserve valuable samples of the Earth’s subsurface for use by scientists and educators representing government, industry, and academia. The CRC collections include full-diameter rock cores, slabbed cores (cut in half longitudinally), well cuttings, thin sections, and associated analytical data. A majority of the material was donated to the CRC by private industrial companies, although some cores and cuttings were collected by the USGS and other government agencies. Rock cores were collected from roughly 9,500 drilled borehole locations representing approximately 610,000 meters (2 million feet) of subsurface strata in 35 states. Many of the boreholes...

Poorly-labeled boxes of rock, sediment, and fossil specimens collected by individual workers at different times. Also, numerous samples of Cenozoic volcanic ashes that may be of unrealized future value as a reference collection. Hand specimens exist in our collections, but they are completely uncataloged and are improperly stored. This collection may be discarded as additional space restrictions are imposed.

Lithology logs from oil and gas wells and stratigraphic tests in various formats, particularly strip logs and lithologic logs of cuttings produced by stratigraphy consulting firms.

Location data for exploratory, sciencific, or engineering borings conducted statwide since the early 1900s. Drill Core and/or other samples from a large number of these borings are stored in the DNR's Drill Core Library in Hibbing, Minnesota. For more information on the drill core library please vist the DNR's webpage: http://www.dnr.state.mn.us/lands_minerals/dc_library.html

Seismic reflection data (in nautical miles) collected mainly from off-shore New Jersey for beach sand replenishment investigations. This collection has not been inventoried. However, materials are available to the public for research and investigation.

The Historic Images Collection includes approximately 15,500 photographs, slides, lantern slides and digital media in this collection were taken during the course of geologic, mineral resource, and geologic hazard investigations carried out by Virginia Energy staff beginning in the first half of the 20th century. The collection includes images of important rock outcrops that demonstrate key features of stratigraphic units, fossils indicative of the age of rock formations, outcrop-scale geologic structures such as faults and folds, economically significant minerals and mine sites, and geologic hazards such as landslides and sinkholes. Images are available online in JPG format. High resolution imagery is available...
As part of its Geologic Legacy Program, the NJGWS scanned and digitized documents from recently retired geologist Richard Volkert. These documents scanned included 46 bedrock geology field notebooks.
