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.

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 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...

Collections of physical samples and data managed and preserved by the U.S. Geological Survey (USGS). The separate collections are managed by different projects and Mission Areas of the USGS. The collections are distributed across the United States, in various USGS offices. Preservation of some of these collections may be supported by the National Geological and Geophysical Data Preservation Program. USGS strives to publicly expose its materials, data, and other research to further scientific inquiry. Points of contact for individual collections may be contacted to request access to materials and data.

The mission of the Colorado Geological Survey is building vibrant economies and sustainable communities, free from geologic hazards, for people to live, work and play through good science, collaboration, and sound management of mineral, energy and water resources. Geoscientific collections managed by Colorado Geological Survey are aggregated in the National Digital Catalog to enhance discovery and use of valuable samples and data for further scientific research. Contact information and material access instructions are provided for the individual collections.

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...
