The collection consists of (a) approximately 50 field notebooks from geologic mapping, including field maps showing outcrop locations corresponding to the field notes and in some cases draft copies of quadrangle geologic maps, (b) approximately 20 notebooks and associated sample location maps from the Chesapeake Bay Earth Science Study (CBESS), and (c) 1 notebook from the Hart-Miller Island Monitoring Study. Some notes are in pencil and may be difficult to read.
Beach profiles collected periodically, primarily along the Atlantic coast of Maryland, but also along Chesapeake Bay & tributary shorelines. This collection has not been fully inventoried or catalogued.
Collection consists of paper and electronic files of data from individual wells and springs that have been tested for water quality as part of an ongoing statewide assessment of ground-water quality. Data from the collection is documented in publications and annual administrative reports. Results of groundwater samples collected by the Maryland Geological Survey that were analyzed by the USGS National Water Quality lab have been entered into the USGS National Water Information System (NWIS). Some laboratory results of groundwater sample analyses from state or private labs exist only in paper and spreadsheet format at the Maryland Geological Survey and have not been fully inventoried or catalogeed.
Collection of Data from Aquifer Tests and Other Hydraulic Tests of Subsurface Material from Maryland
The collection consists of Excel files describing each aquifer (pump) test, containing raw data, plots, and calculations of hydraulic properties (currently Coastal Plain only) and a list of references associated with the collection. Approximately 262 well locations currently have digital aquifer test data; approximately 345 well locations have hydraulic properties described in a published report. This collection will continue to expand as data from additional wells is acquired. The long-term goal is to incorporate pump test data from non-Coastal Plain provinces/Piedmont of Maryland as well.
This collection includes paper originals and photocopies of reports beginning in 1936, and PDF scans of these reports, up to 1995. In more recent years, this information is available from the Wisconsin DNR via a computer database. Materials are arranged by county and PLSS locations. There are 326,385 well construction reports in this collection.
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...
40 bedrock samples were collected from surface outcrops in Vermont. Samples are the same set as those analyzed for thermal conductivity as part of the National Geothermal Data System program. All analyses were done at AcmeLabs, Canada. Samples were analyzed using ICP – ES (emission spectroscopy) and ICP-MS (mass spectrometry). 11 major elements plus Ni and Sc were analyzed by ICP-ES following a lithium borate fusion and dilute acid digestion. Analyses include Loss on ignition (LOI) and Leco analysis for total carbon and sulphur. A 45 element suite of trace elements was analyzed using ICP-MS (mass spec). Rare earth elements and refractory elements report from a lithium borate decomposition to give total abundances....

There are over 1,000 individual logs from over 450 different holes across the state. Holes include municipal wells, monitoring wells as well as deep and shallow drill holes. Logs collected may include: gamma, caliper, single point resistivity, self potential, normal resistivity, fluid temperature, fluid conductivity, flow meter - heat pulse, flow meter- spinner, optical borehole imager, and acoustic borehole imager. Locations of boreholes and PDF images and LAS files for more than 700 Geophysical Logs can be viewed at https://data.wgnhs.wisc.edu/data-pres-2018/ . New logs are added to this online map as they are added to the WGNHS sample tracking system, Geobase.
The Connecticut Surficial Materials and Quaternary Geology Quadrangle information was initially compiled at 1:24,000 scale (1 inch = 2,000 feet) then recompiled for 2 statewide 1:125,000-scale maps.

American Metal Climax, Inc. (AMAX) added coal production to its diverse mining, metals, and energy concerns on November 1,1969 through a mutually approved merger with Ayrshire Collieries Corporation of Indiana. Ayrshire boasted a long and productive lineage, originating with the first mines established by Scottish immigrant, David Ingle, in the early 1850s near Evansville, Indiana. The Ayrshire name persisted through subsequent purchases of mine shafts by Electric Shovel Coal Corporation in 1927 and a merger with the Patoka Coal Company in 1939, but was rebranded as AMAX Coal Company on January 1, 1972. It became America's third-largest coal producer by 1975. Drilling records in this collection relate to the company's...
Collection of Cores and Sediment Grab Samples collected from Maryland Chesapeake Bay and Tributaries
To date, the collection consists of about 4,200 unprocessed, surficial sediment (grab) samples collected by Maryland Geological Survey (MGS) from the bottom of the Maryland Chesapeake Bay and its major subestuaries between 1976-1984, as part of the Chesapeake Bay Earth Science Study (CBESS), a multidisciplinary research effort authorized by Maryland and Virginia through the U.S. Environmental Protection Agency (EPA). MGS collected samples according to two sampling schemes, mid-bay and nearshore, and then processed them to develop a baseline inventory of certain physical and geochemical characteristics of bay bottom sediments, in particular, water content, grain size composition, and carbon and sulfur content. Since...
Unpublished reports, usually associated with a specific project involving Maryland Geological Survey (MGS) staff. Generally, these are file reports or open-file reports that meet the terms of a grant or contract but are not otherwise distributed or included in the MGS List of Publications. They are commonly, but not necessarily, associated with a particular collection(s). Reports, both paper and digital, need to be collected in a central location, organized, catalogued, and archived. Eventually, they should all be digitized/scanned and be made available electronically.
X-rays and xeroradiographs of marine and estuarine sediment cores collected in Maryland, taken prior to core extrusion. Cores, generally obtained using gravity or box coring equipment, are usually 1-2 m long. This collection has not yet been fully inventoried or cataloged. Need to coordinate cores and all data derived from cores; need to determine best way to store x-rays to preserve them.

This dataset is a collection of unpublished geologic field maps and transfer maps that represent over 100 years of field data collected by Virginia geological survey staff. These field records include hand-drawn notes, strike and dip, contacts, economic, structure and paleo information. Some maps have been scanned and are available digitally. Most maps are located in our Charlottesville, Va offices in paper format. All are unique, one-of-a-kind documents.
Thin sections prepared primarily in the course of research conducted by geologists of the Wisconsin Geological Survey. There appears to be a set of USGS-related thin sections, as well, but these are not evaluated at this time. Thin sections are tied to field notebooks, which are being reviewed as time allows. Certain physical collections have been located, but their geographic location is uncertain until the field notebooks can be tied to the actual thin section. We must tie physical materials to field notebooks in order to develop geographic coordinates for specific thin sections. Work to date has identified locations of physical items and is currently focused on assessing the notebooks themselves. There are 1,700...
Cores represent over 2,000 individual core sites drilled across the State of Wisconsin; stored in over 56,000 (mainly cardboard) boxes; representing approximately 650,000 linear feet of the subsurface. The Flambeau Core subcollection is approximately 3 percent of the collection of rock cores from Wisconsin. Documentation for the Wisconsin core collection is routinely updated, as information becomes available.
This collection includes folders that contain coal chemical data from Indiana, collected before 1990. This collection is publicly accessible.
