Field notebook of the New Jersey Geological Survey written by Meredith Johnson; statewide field notes, various locations, differing tasks, personal correspondences
Categories: Data; Tags: ndc_collection
the NJGWS scanned the Mineral Commodities Books in its possession. There are six books in this collection. They date from the late 1800’s to about 1915 and include all mining activities and statistics reported to the NJ Geological Survey during those years.

This collection (known internally at Maryland Geological Survey as Component 8) consists of 211 infrared, 9 in. by 9 in. aerial photographs (211 unique frames) flown on a 7.5-minute U.S. Geological Survey (USGS) quadrangle basis. The photographs date from 1988-1989 and were flown or otherwise acquired by the USGS National Aerial Photograph Program (NAPP). The Maryland counties covered by these photographs include Allegany, Anne Arundel, Calvert, Cecil, Charles, Dorchester, Kent, Prince George’s, Queen Anne’s, Somerset, St. Mary’s, Talbot, Washington, and Worcester Counties. The scale of these photographs is not printed on the photographs; however, Maryland Geological Survey (MGS) calculates the scale to be approximately...

Paper copies of chemical analyses made at Illinois State Geological Survey from approximately 1932 to 1995. Includes chemical analyses for approximately 30,000 coal samples, 20,000 rock samples, 5,000 gas samples, 5,000 brine samples, and 5,000 water samples.

Collection includes cores extracted during drilling operations including the U.S. Geological Survey for the purposes of site investigations in the Meddybemps township. Please contact the Maine Geological Survey to discuss access to the collection.

Flynn Creek crater is a 3.8 km diameter, 360-million-year-old impact structure located in north central Tennessee, and is an invaluable terrestrial analog for the study of impact cratering dynamics. The Flynn Creek Crater Sample Collection consists of over two thousand boxes of drill core from 18 drill holes in the crater’s central uplift, floor, and rim. Impact-induced hydrothermal systems are of considerable scientific interest because they may have played a significant role in the origin and evolution of life on early Earth and produced temporary near-surface habitable environments on Mars. Between 1967 and 1979, USGS scientist Dr. David Roddy conducted a drilling program at Flynn Creek crater. The drilling...

Map Package format. Structure point data set containing locations and structure type, with strike and dip (planar features) and trend and plunge (linear features). The symbology is derived from ESRI Representations associated with the SymbolFGDCLookup table in the geodatabase. Most trends and dips are based on field measurements using Brunton or similar compass. A sun compass was employed in areas of strong magnetic signature, such as iron-formation. Contains bedrock structural measurements acquired by the multiple field geologists over 40+ years. Collected from bedrock exposures and from data transcribed from published and unpublished analog (non-digital) maps. To access the full data set, download using the link...
This is a collection of rock cuttings, which are washed or unwashed, housed in the Bureau of Economic Geology’s Core Research Centers.

The current database consists of location 9,032 entries. The surface-based, point data include 5,272, 6,939, and 903 density, magnetic susceptibility, and NRM measurements, respectively. Downhole data from 146 drillcore have also been incorporated, yielding an additional 1,145 and 9,622 measurements of density and magnetic susceptibility, respectively. Geologic interpretation of gravity and magnetic anomaly data in a given area is greatly enhanced if density, magnetic susceptibility (MS) and natural remanent magnetization (NRM) data are available for representative rock-types (Chandler and others, 2008). Along with geologic information from outcrop and drill-holes, rock property data help relate geophysical anomaly...
This is a collection of rock cores, which are whole or slabbed, housed in the Bureau of Economic Geology’s Core Research Centers.
This is a collection of thin sections, primarily from rock cores, housed in the Bureau of Economic Geology’s Core Research Centers.

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.

The 3002’ length core was extracted from the Redstone Quarry in Conway, NH in 1975 as part of an evaluation of geothermal potential produced by the natural decay of several radioactive minerals present in the Jurassic age Conway Granite pluton. The core extracted from the borehole at the Redstone Quarry is the deepest core drilled in New Hampshire. The Redstone Core project was part of a collaboration between the New Hampshire State Geologist and the U.S. Energy Research and Development Administration. Significant geothermal resources were not found. NHGS estimates that approximately half of the original 3002’ foot core remains in core boxes with sufficient documentation tags to identify the depth intervals each...

Collection includes rock cores extracted during drilling operations for Getty - Mount Chase base metal exploration. Please contact the Maine Geological Survey to discuss access to the collection.
Collection includes cores extracted over decades by mineral exploration firms as they completed their Maine work or otherwise released their data, covering both public and private lands that were the subject of mineral exploration. These records represent the best public collection of the major mineral exploration efforts of the 1960s-1980s. This collection of 595 scanned core records is accessible through a Google Earth application. Please contact the Maine Geological Survey to discuss access to the collection.

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

The U.S. Geological Survey (USGS), in cooperation with the Arkansas Geological Survey (AGS), has gathered available geophysical logs and related data from the USGS office archives in Arkansas and Tennessee as a basis for developing a hydrogeologic framework for the Southeast region of the United States. Similar efforts were undertaken by the Mississippi Embayment Regional Aquifer Study (MERAS) and the Regional Aquifer-System Analysis (RASA) Program. The logs compiled for these older efforts were difficult to access from the paper files; however, and partly because of this, older and newer logs were compiled into a single digital database for the current study.
