All core samples on file at the KGS Earth Analysis Research Library. Includes continuous or interval cores on file at the KGS Earth Analysis Research Library in Lexington, Kentucky. Core samples range from PreCambrian to Mesozoic in age and are derived from oil and gas wells, coal or mineral exploration wells, geotechnical wells, and hydrologic investigation wells.

The Florida Geological Survey (FGS) maintains a collection of geologic samples from throughout Florida. This includes core samples from boreholes drilled by the FGS as well as those received from the drilling of water production wells, monitor wells, injection wells, and stratigraphic testing boreholes. The core sample collection currently includes: continuous core (CCR); Standard Penetration Test (SPT) samples; individual core segments (COR); core chips (CHP); rotosonic core (RTS); and vibracore (VBC). The collection also includes samples that are from the secondary analysis of core specimens, which we have catalogued as “secondary samples” (SAS) and “representative samples” (REP), which are often sediment or...

The Florida Geological Survey (FGS) maintains a collection of geologic samples from throughout Florida. This includes cuttings samples recovered from drilling in the rock below the softer surficial sediments of Florida at intervals of 5, 10 or 20 ft. The FGS cuttings collection contains both washed and unwashed samples. Clay samples can easily be washed away when processing samples, so an unwashed set is kept for all samples. Samples are stored by interval in paper sample envelopes which are then stored in cardboard boxes. The collection includes over 39,000 boxes, which each hold an average of 380 ft per box. We have an estimated 13.1 million feet of cuttings in our collection, ranging from shallow sample sets...

This collection consists of written descriptions of lithologies encountered during the drilling phase of various coal exploration programs in Tennessee. Descriptions range from detailed to brief. Information obtained primarily from diamond core drilling with additional information from rotary drilling and e-logs. Drill hole depths range from tens to thousands of feet deep. Individual drill holes were originally located by using the Tennessee State Plane Coordinate System (NAD 27). Quadrangles with abundant drill holes have accompanying drill hole location maps.
Collection includes rock core from Michigan oil, gas and mineral wells collected by the Michigan Geological Survey and archived at the Michigan Geological Repository for Research and Education, Department of Geosciences, Western Michigan University, Kalamazoo Michigan. Core representative of 2022 Michigan oil, gas and mineral wells, preserved in core boxes.

The documents in this collection represent material that the Tennessee Geological Survey has acquired from numerous sources over the years. Many of the documents were donated by former employees of zinc companies that once operated in the state. Additional documents represent originals and copies of U.S. Geological Survey files related to the war minerals exploration program conducted in the 1940's, as well as unpublished work completed by the Tennessee Geological Survey. The material includes drill hole logs, geologic maps, cross sections, reports, geochemical analyses, mine maps, and internal company correspondance. All of the documents in the collection are available in digital format as Portable Document Files...

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.

Field notes dating back to early 1900s are kept in the Washington Geological Survey library. Hundreds of volumes exist in the physical collection. Last notes in the library are from the 1980s when available space become a limitation. More recent notebooks are either retained by active staff or kept in the offices and at risk of being discarded. A storymap describing the collection is available at https://storymaps.arcgis.com/stories/77e291f5658a40af80029e025a8735e6

The Montana Bureau of Mines and Geology (MBMG) compiled and maintains historical, engineering and geologic reports, pictures, correspondence, news clippings, and production information for over 4,400 property-specific records. A record or file may contain information related to a particular mining claim, a collection of claims, or a mining exploration project. The Mining Property File records are organized by Montana county and mine or project name. To research the collection, visit our website at http://www.mbmg.mtech.edu/mining-archives/mining-archives_data.asp.

This collection consists of field notebooks, related maps, and photographs from former Tennessee Geological Survey staff, contractors, and students that worked on Survey projects. As of 2020, the metadata records pertain only to field notebooks and related maps; the photographs in the collection will be completed at a later date.

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...

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...

Collection consists of 88310 paper well logs (including mud logs) from 46808 oil and gas wells, which are located almost exclusively within New Mexico, with a small percentage of the well logs in our collection coming from the neighboring states of Arizona, Utah, Colorado, and Texas. This collection has been built over the past 60 years by accepting donated well logs. Many of the logs contain significant handwritten material such as formation tops, perforated, intervals, etc. Please contact us for a copy of our current log list.

This collection consists of bedrock core drived from mineral exploration test holes, coal exploration test holes, and oil and gas exploration test holes. The mineral exploration test holes are primarily associated with zinc exploration in East and Middle Tennessee. There are approximately 475 test holes currently stored in 3 locations in middle Tennessee. The locations are the Ellington Warehouse in Nashville, Tennessee, a TGS Core Storage Facility in Waverly, Tennessee, and a storage building on TVA property in Hartsville, Tennessee. Total estimated volume for housing cores is 39,000 cu. ft. Only 99 test holes are currently included in the National Digital Catalog, but ongoing efforts are underway to compile...

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.
