The New Jersey Zinc Company Historical Collection contains details of mining operations at the Austinville-Ivanhoe underground lead-zinc mines located in Wythe County in southwestern Virginia from 1902 to 1981. This site also operated under the name Bertha Mineral Company. The records pertain mainly to the historic Austinville-Ivanhoe underground lead-zinc mines located in Wythe County. The site produced zinc and lead from underground mines in the historic Austinville-Ivanhoe mineral district located in Wythe County. During this nearly 80-year span of continuous mine operations near Austinville, the company also conducted base metals exploration in other regions of Virginia, including the Timberville lead-zinc...

This part of the release provides an updated georeferenced catalog of limestone boulders and cobbles pertaining to extreme waves on Anegada, a low Caribbean island perched south of the Puerto Rico Trench. Tabulated are 660 limestone clasts, along with clast dimensions and long-axis trend in many instances. Fewer than one-fifth of the clasts were reported previously in https://doi.org/10.1007/s11069-011-9725-8 and https://doi.org/10.1130/GES01356.1. Most were surveyed in 2017.
This collection consists of samples of the Entrada Sandstone and Pony Express Limestone from the Placerville vanadium-uranium district in southwest Colorado. The samples were collected under the direction of Harry Granger to compare some of the geochemical attributes of the Placerville district deposits to the more widespread Salt Wash hosted deposits. These samples were also used by George Breit for research to determine an age of the roscoelite (V-illite). Samples are stored in fabric bags in cardboard boxes on one wood pallet.
This location is part of the Arizona Mineral Industry Location System (AzMILS), an inventory of mineral occurences, prospects and mine locations in Arizona. Gila172B is located in T1N R15.5E Sec 14 NW in the Globe - 7.5 Min quad. This collection consists of various reports, maps, records and related materials acquired by the Arizona Department of Mines and Mineral Resources regarding mining properties in Arizona. Information was obtained by various means, including the property owners, exploration companies, consultants, verbal interviews, field visits, newspapers and publications. Some sections may be redacted for copyright. Please see the access statement.

From the US Bureau of Mines map publication, "Availability of Federally Owned Minerals for Exploration and Development in the Western United States". The Bureau of Mines inventoried Federal mineral land in Wyoming and assessed the availability of this land for mineral exploration and development as affected by legal status and agency management practices. To illustrate the impact that various Federal land use decisions have on the mineral industry, the USBM also identified and ranked known mineral deposit areas (KMDAs)-i.e., areas having past or present mineral production and /or known mineral resources- and compared these areas spatially with availability of Federal mineral lands. Most Federal minerals, except...

This part of the data release aids in identifying places where land-clearing and wall-building, rather than a sea flood, may account for anomalous boulders and cobbles of Pleistocene limestone on Anegada. The wall shapefile delineates much of a network of walls found mainly on the east half of the island. It can be plotted in GIS with the shapefile of limestone clasts, most of which form boulder fields that trail southward from limestone knolls, promontories, and other outcrops. The comparison shows that these clast fields are most abundant on low ground in and near salt ponds, while the walls run mostly on higher ground.

May sea floods contaminate Anegada groundwater by entering a freshwater aquifer through sink holes? Groundwater provides the island's main naturally available source of freshwater. Robert Schomburgk in 1832 reported natural wells provided by holes in limestone (https://library.iucn-isg.org/documents/1832/Schomburgk_1832_The_Journal_of_the_Royal_Geographical_Society_of_London.pdf). Today, sinks in the limestone are readily mapped today in lidar topography. The dataset here identifies 1,508 closed topographic depressions. Several holding water were examined during field work in 2008–2017. The water level in them was close to mean sea level, as estimated from differences between lidar elevations of rims and depths...

geoscientificInformation,
An extensive archive, estimated to contain more than 3,500 historical (1925–2020) geophysical logs collected in conjunction with past studies conducted by various entities, and more than 2,000 additional donated well and geophysical logs are stored in hard-copy at the Central Texas Branch of the Oklahoma-Texas Water Science Center (OTWSC) located in Austin, Texas. This dataset addresses the need to preserve these records electronically by providing a scanned and indexed collection of 6,058 of these records in Portable Document Format (PDF) along with a public Microsoft Access database and comma-separated values (CSV) text file containing detailed well header information for each record.
