Cuttings from mud-rotary test holes through regolith and shallow bedrock. Cuttings from test holes drilled as a part of the Nebraska statewide test-hole drilling program since 1940 and continued through funded programs such as USGS STATEMAP cooperative geologic mapping.

about 90% Precambrian, nearly all related to mapping projects, most from recent decades total to the nearest thousand

The Borehole Database for Virginia provides information about boreholes drilled by Virginia Energy as part of on-going geologic mapping studies conducted in the Coastal Plain of Virginia. This collection is available for study and sampling by scientists, citizens, government agencies, and by industry. Virginia Energy maintains this collection to support the wise use of Virginia's resources by providing quality geologic and mineral resource information. The collection includes records for approximately 1,800 boreholes, with location information, lithologic log, and interpreted formation contacts. These boreholes were drilled for water wells, geologic research, geotechnical engineering studies, and environmental...

This collection (known internally at Maryland Geological Survey as Component 5) consists of 4,720 items – 4,715 black-and-white aerial photographs (4,688 unique frames plus 27 duplicates) and 5 associated index maps. The aerial photographs were flown or acquired by the U.S. Geological Survey (USGS) and organized on a 7.5-minute quadrangle basis. The photographs are black-and-white and approximately 9 in. x 9 in. in size. The scale of the aerial photography varies but ranges from approximately 1:12,000 to 1:35,400. These photographs date from 1936-1991 and were donated to the Maryland Geological Survey (MGS). The index maps serve as a finding aid for several of the flight series flown over five quadrangles...

The Minnesota drill core repository is managed by the Department of Natural Resources, in relation to a legislated obligation to submit a one-fourth portion of core samples obtained for mineral exploration. These samples become property of the state and are stored in the DNR's drill core library, located in Hibbing. The original drill core library was constructed in 1972. The most recent additions were constructed in 1990, and were subsequently expanded in 1995. Construction presently is underway on an expansion. The existing facility contains nearly 2.3 million feet of core, extracted from 79 Minnesota counties during the period from 1905 to the present.

Thin sections, nearly all Precambrian rocks, nearly all related to mapping projects; many several decades old total to the nearest thousand

This is the collection of original paper gamma-ray logs, copies and other items that are associated with the gamma-ray logs housed at the Indiana Geological Survey. They are stored in 12 file cabinets. This represents all of the original paper copies since 1978 when the collection began. Each log can be found filed in the original file, used mainly as a master file, as well as by county, the working file. The paper logs have been digitized made available to the public at https://igws.indiana.edu/borehole-logs in .las and .pdf format.

Collections of 1 x 2, 1 x 3, and 2x 3-inch petrographic thin sections, mostly of sediments and sedimentary rocks from Nebraska. A few thin sections of igneous and metamorphic rocks from the subsurface of the state, and a few incidental thin-sections from various specimens collected outside of the state.Several full and emeritus faculty members (at least 5) have individual holdings of thin sections generated in the process of performing geological survey duties.Collections will almost certainly be lost in the absence of an enforced acquisition policy.

Cuttings from petroleum exploration and production wells. Cuttings retrieved from oil and gas wells in Nebraska.

The well and borehole collection contain various records for wells drilled in Illinois, including driller's log, drilling time log, drill stem test report, core analysis report, commercial scout tickets, permit, casing report, well drilling report, well completion report, plugging affidavit, and geophysical logs. Data is available in ILOIL https://www.isgs.illinois.edu/illinois-oil-and-gas-resources-interactive-map and ILWATER https://www.isgs.illinois.edu/ilwater

Cores of surficial sediments (loess, till, alluvium, etc.) and soil.Cores of unconsolidated surficial sediments and soils, primarily in eastern Nebraska, were drilled almost exclusively by hollow-stem augering. Some shallow Giddings probe cores also exist in the collections.

Miscellaneous field notebooks from survey personnel, mostly dating prior to 1970. Field notes from current and past employees of the Conservation and Survey Division. These materials are to be left with the organization upon retirement, but this policy has not been enforced.
