This collection (known internally at Maryland Geological Survey as Component 7) consists of 48 high-altitude, 9 in. by 9 in. infrared aerial photographs (48 unique frames). The photographs date from 1970-1974 and were flown over ten counties in Maryland and some small portions of Virginia along the Maryland border. The counties in Maryland covered by these photographs include Anne Arundel, Baltimore, Calvert, Carroll, Charles, Frederick, Harford, Howard, Montgomery, and Prince George?s Counties. The scale of these photographs is not printed on the photographs; however, Maryland Geological Survey (MGS) calculates the scale to be approximately 1:120,000 for the Series 74-039 photographs; approximately 1:140,000...

John Kinnison earned his master's in geology from the University of Arizona in 1958. He spent over twelve years with ASARCO. He was a consultant to the mining industry from 1973 to the early 1980s. He specialized in porphyry copper exploration in the Southwest U.S., but also worked in Mexico, Canada and the Western U.S., exploring base and precious metal veins and replacements, uranium, mercury, and gold placers. His professional work included management, target generation, ore reserves and mine evaluation. He had a professional history of general exploration, mine geology, sampling methods, surface mapping, extensive reconnaissance observation and mapping, and successful exploration for new ore deposits. The collection...

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 Additional radiometric dates were compiled from both published and unpublished sources.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 consists of a wide range of mineral resource related items. It includes detailed and summary reports, memoranda, correspondence, notes, maps, and other documents. The documents were produced by former staff working for theTennessee Geological Survey, United States Geological Survey, and Tennessee Valley Authority. As of 2015 nearly all of the items in the collection located in the Knoxville Field Office have been reviewed and scanned, and are included in the metadata records here. The documents are all available in digital format as Portable Document Format (PDF) files. High resolution tagged image format (tif) files are available for the large plates. Currently all of the original documents...

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.

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...

This collection (known internally to Maryland Geological Survey as Component 5A) consists of 103 photo-mosaic index maps (89 unique maps plus duplicates) dating from 1955-1981. The date printed on the index map (and listed in the metadata) is the date that flying (photography) was completed for each index map. Each photo-mosaic index map shows individual aerial photographs (with Flight Lines and Frame numbers) in a particular U.S. Geological Survey (USGS) 7.5-minute or 15-minute quadrangle in Maryland, Delaware, New Jersey, Virginia, or West Virginia. These index maps are black-and-white and approximately 10 in. by 12 in. in size. This collection serves as a finding aid for a portion of the Quad-Based Aerial...

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

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.
