Continuous bedrock core from about 50 sites across CT. Stored in 1100 boxes. This collection has been rescued three times since its formation in the late 1980's. Formerly administrative responsibility was shared between the University of Connecticut Dept. of Geology and Geophysics (now disbanded) and the Dept. of Environmental Protection, Geological and Natural History Survey. The State Survey now houses the collection and is the sole administrator.
The Montana Bureau of Mines and Geology (MBMG) Mining Property File collection was amassed over the years through private and industry donations of engineering and geologic reports, pictures, correspondence, news clippings, and production information. The collection presently contains over 4,400 property-specific files (records). The physical files are organized first by Montana county and then by mine or project name. Files may contain information related to a particular mining claim, a collection of claims, or a mining exploration project. Metadata describing each record includes property name, location (county, historical mining district, township, range and section), georeferences (latitude and longitude), and...

Petrographic slides of New Mexico and surrounding areas used in Adam Smith's 2018 thesis: Multi-stage processes affecting the generation of REE-enriched episyenites and fenites in NM and Colorado: the role of magmatic and diagenetic fluids based on 40Ar/39Ar geochronology, whole rock geochemistry and radiogenic isotope. Field work was partially funded by New Mexico Bureau of Geology and Mineral Resources.
Field notebook of the New Jersey Geological Survey written by Meredith Johnson; statewide field notes, various locations, differing tasks, personal correspondences
Thin sections were scanned at 1x1 scale then enlarged in photoshop to make the features easily veiwable. Cross polarization film was used to create the cross polarized scans. This is a collection of thin sections from the state of New Mexico representing some of the formations in the state. Funding was provided by NGGDPP award G18AS00010.
This collection (known internally at Maryland Geological Survey as Component 9) consists of 1,474 black-and-white aerial photographs (1,472 unique frames plus 2 duplicates) plus 2 index maps which serve as a finding aid for the photographs in the two sub-components of this collection -- DC Collection 1 and DC Collection 2.

The counties in Maryland covered by these aerial photographs are Anne Arundel, Howard, Montgomery, and Prince George's Counties. No date is printed on these photographs; however, based on features shown in the photographs, Maryland Geological Survey (MGS) estimates...
Richard (Dick) Hahman was born in Buffalo, New York, in 1936. He grew up in coal mining towns in Pennsylvania, then later in Washington, D.C. He received his master's in geology from the University of West Virginia. His career took him through the U.S., Canada, Mexico, and Chile. He worked for several companies in Tucson, Arizona, before going to work for Conoco Inc. in Oklahoma City in the early 1980s. In the late '80s he started his consulting company, Hahman & Associates, in Las Cruces, New Mexico. He moved back to Tucson around 1997. The collection contains geologic reports, drill logs, maps, assays, photos and field notes from exploration in Arizona and New Mexico.
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.
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.
