Data

This U.S. Geological Survey (USGS) Data Release provides a digital geospatial database for the bedrock geologic map of the Beans Cove and Hyndman quadrangles and part of the Fairhope quadrangle (de Witt, 1974). Attribute tables and geospatial features (points, lines, and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent the geologic map as published in the...

The Surprise Hill core was drilled on the Northern Neck, Northumberland County, Virginia. The studied section consists of glauconitic quartz sands of the upper Paleocene Aquia Formation and silty clays of the lower Eocene Marlboro Clay. Data from this core were compared to the previously documented South Dover Bridge and Howards Tract cores from Maryland. The purpose of this study was to...

The database for the Washington West 30- by 60-minute quadrangle covers an area of approximately 4,884 square kilometers (1,343 square miles) in and west of the Washington, D.C., metropolitan area. The eastern part of the area is highly urbanized, and more rural areas to the west are rapidly being developed. The area lies entirely within the Chesapeake Bay drainage basin and mostly...

This data release contains photographs and photomicrographs from drill cores and cuttings of pre-Middle Jurassic basement rocks that are buried beneath Coastal Plain sedimentary deposits in Florida. These samples provide rare insights into deeply buried rocks that have no surface exposures and no known exposed correlates. These images were acquired to support the characterization...

This data release reports the mineral abundances in samples of pre-Middle Jurassic basement rocks from twenty-nine (29) boreholes in Florida and southern Alabama. Mineral abundances are quantified from whole-rock powder X-ray diffraction (XRD) data and the Rietveld method and are reported in weight percent or, where present near the detection limit (~1 wt.% depending on mineral), as...

The Salinity and Temperature Data for South Florida Estuarine Mollusks (1994-present) database contains salinity and temperature readings from modern monitoring sites where live mollusks were observed during fieldwork performed from 1994 to present, salinity and temperature summary statistical data for each species, and location information about the sites where the monitoring data were...

The bedrock geologic map database of the Woodstock quadrangle consists of highly deformed metasedimentary rocks of the Central Maine trough, including the Silurian Rangeley and Perry Mountain Formations and the Devonian Littleton Formation. The central, northern, and eastern parts of the quadrangle are underlain by the oldest rocks in the area, the Rangeley Formation. In the southwest...

The database for the Buckner 7.5-minute quadrangle straddles three terrane boundaries in the Piedmont Physiographic Province in central Virginia: the Chopawamsic terrane, the Elk Hill Complex, and the Goochland terrane. In much of the map area, the Elk Hill Complex separates the Chopawamsic and Goochland terranes. Rocks of the Chopawamsic terrane include Ordovician metavolcanic and...

Cobalt, designated a critical mineral by the European Union and the United States, is a crucial component of the lithium-ion batteries found in cell phones, electric vehicles, and personal computing devices. Over half of the world’s cobalt supply is produced in the Democratic Republic of the Congo (DRC), where cobalt is mined in both large-scale and artisanal or small-scale operations...

This study applied historical aerial imagery and satellite imagery to create digital surface models (DSMs) of the Helmand River Valley situated in southwestern Afghanistan. The historical imagery, collected in 1952 by Fairchild Aerial Surveys Incorporated (FAS), at 1:40,000 scale, represents the earliest known aerial photographic archive of the Helmand Valley landscape. Structure-from...

This dataset is derived from Synthetic Aperture Radar (SAR) data collected between July 2022-December 2024 and focuses on water inundation patterns on Jim Foot Key, located within Florida Bay. The dataset includes 13 TIFF files at 0.5 meter-3 meter horizontal resolution, that have undergone preprocessing and water thresholding methods to identify areas of inundation. These analyses were...

Manganese is a designated critical mineral, being industrially utilized for producing steel and batteries, including in the production of electric vehicles (Rozelle et al., 2021). The eastern United States hosts hundreds of manganese oxide mines that served steel production until their abandonment in the mid-twentieth century (Pegau, 1958). Many relict mines still feature accessible pits...
