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.

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.

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.

The County Well Index database was initiated by MGS, and is now a collaborative effort of MGS and the Minnesota Department of Health (MDH). Much effort is committed to compile, add value, and distribute data from drilling done mostly by well contractors across the state. The MGS role is in categorization and correlation of materials intersected by drilling, as MDH administers well regulation. This GIS-based system contains basic information for over 540,000 wells drilled in Minnesota, and single-copy paper records are on file for about 100,000 additional sites. The entire well record including construction information such as casing, screen and pump information, hydrologic data, and descriptions of geologic materials...

Collection includes rock cores extracted during drilling operations by Billiton Metals and Ores for tin exploration in Waterville, Winslow. Please contact the Maine Geological Survey to discuss access to the collection.
As part of its Geologic Legacy Program, the NJGWS scanned and digitized documents from recently retired geologist Richard Volkert. As part of this project the NJGWS digitized of approximately 17,297 field locations from his field maps and notebooks.

Collection of data from the Lead-Zinc District of Northwestern Illinois. Collection includes borehole data, driller logs, descriptive logs, formation tops, and downhole lead, zinc, and iron concentrations from mining operations circa 1900-1980. Sources of the collection include original mining company records and maps, maps and logs from the US Bureau of Mines "Illinois Mineral Development Atlas", and Illinois State Geological Survey records.

Static metadata (current to August 2018) of Minnesota's borehole geophysical log collection maintained by the Minnesota Geological Survey. This collection is web-accessible through the MGS Open Data Portal at https://z.umn.edu/borehole_geo, where users can obtain the most up-to-date information pertaining to old and new borehole geophysical logs and download corresponding PDF and LAS files for each log (if available). The Borehole Geophysical Database (BGD) is a collection of over 7000 borehole geophysical logs of water wells and drill holes throughout Minnesota. Database collections reside at the Minnesota Geological Survey (MGS) and are continually maintained and expanded upon by MGS staff as part of MGS mapping...
