Presence-absence data for planktic foraminifera from selected samples.
Structural geology data collected in the South Merrimack quadrangle, New Hampshire Structural geology data collected in the South Merrimack quadrangle, New Hampshire
This data release includes structural geology measurements collected in the South Merrimack quadrangle, New Hampshire. Data were collected between December 2025 and September 2026, in cooperation with the New Hampshire Geological Survey. The quadrangle is underlain by metamorphic and igneous rocks. Structure data includes measurements of fractures at outcrops and roadcuts. The data...
Geochemistry and mineralogy of the Josephine Peridotite of California and Oregon Geochemistry and mineralogy of the Josephine Peridotite of California and Oregon
This data release includes whole rock geochemical data from 33 samples and mineralogical data from 12 samples of the Josephine Peridotite in California and Oregon. Rock samples were collected in 2024 by Naomi Becker and Katie Tognotti. Whole rock geochemistry data were analyzed by contract lab through the U.S. Geological Survey's Mineral Resources Program at the Geology, Geophysics, and
Geochemical data, thin section images, and modal mineralogy of selected bedrock samples from the Halifax County complex, North Carolina Geochemical data, thin section images, and modal mineralogy of selected bedrock samples from the Halifax County complex, North Carolina
This data release contains geochemical data, thin section images, and modal mineralogy from bedrock samples of the Halifax County complex in North Carolina. The geochemical data comprise whole-rock major oxide and trace element abundances in 11 samples. Modal mineralogy was obtained by powder X-ray diffraction and the Rietveld method of the same 11 samples. Pairs of thin section images...
Multi-proxy sedimentological data from U.S. Army Base Fort Drum, Jefferson County, New York, 2026 Multi-proxy sedimentological data from U.S. Army Base Fort Drum, Jefferson County, New York, 2026
The dataset documents results from particle size analysis (PSA), portable X-ray fluorescence (pXRF) analysis, and Munsell color values for a suite of sediment samples collected from U.S. Army Base Fort Drum, Jefferson County, New York in 2026. These samples were collected to obtain representative samples of surficial geologic map units. This Data Release is related to ongoing USGS...
Structure from Motion 3 m DEM of Vicksburg, MS created from 1938 aerial imagery Structure from Motion 3 m DEM of Vicksburg, MS created from 1938 aerial imagery
The dataset is a 3 m spatial resolution Digital Elevation Model (DEM) representing terrain heights in northern Vicksburg, MS and Vicksburg National Military Park in 1938. The DEM was created using structure from motion-aided (SfM-aided) photogrammetry techniques in Agisoft Metashape (v 2.1.1). The aerial images were acquired on June 30, 1938 by Pan American Aerial Surveys for the U.S...
Conodont and petrographic information to support 1:24,000-scale geologic mapping of the Cambrian and Ordovician rocks of the southern Lake Champlain valley Conodont and petrographic information to support 1:24,000-scale geologic mapping of the Cambrian and Ordovician rocks of the southern Lake Champlain valley
Conodonts were collected in the southern Lake Champlain valley to aid in identifying lithostratigraphic units, determining biostratigraphic zonations, and correlating to other regions. The conodonts were identified by experts in Cambrian and Ordovician micropaleontology. Microslides/thin sections were made of different lithostraphigraphic units of the southern Lake Champlain valley to...

This data release contains all new glassy-only single-test stable isotope data from International Ocean Discovery Program (formerly Ocean Drilling Program) Sites 846 and 929, in addition to image plates containing photographs of every Cibicidoides test analyzed. This dataset and associated plates are part of a larger manuscript, which will be submitted for consideration to the journal...
Whole rock geochemistry data from Mesoproterozoic rocks in the Paradox Lake quadrangle, Essex County, New York Whole rock geochemistry data from Mesoproterozoic rocks in the Paradox Lake quadrangle, Essex County, New York
This data release includes whole rock (WR) geochemical data. Bureau Veritas Commodities Canada Ltd. Laboratories in Vancouver, British Columbia, Canada analyzed the samples. Meghan Toft and Greg Walsh collected the rock samples from outcrops in the 7.5-minute Paradox Lake quadrangle, New York. The whole rock geochemistry data constrain the composition of mapped rocks in the eastern...
Northwestern Bay of Bengal (IODP Site U1445) Late Pliocene Paleosalinity Estimates Northwestern Bay of Bengal (IODP Site U1445) Late Pliocene Paleosalinity Estimates
Data are estimates of salinity based upon down-core planktic foram assemblages.
Maceral reflectance data for a release and recapture analysis of limited carbon mobilization in sediment adjacent to Central Atlantic Magmatic Province Sills, Florida, USA Maceral reflectance data for a release and recapture analysis of limited carbon mobilization in sediment adjacent to Central Atlantic Magmatic Province Sills, Florida, USA
Large Igneous Provinces (LIPs) are associated with dramatic changes to the Earth system; their rapid release of carbon to the surface environment may initiate catastrophic climatic changes that cause mass extinction. This carbon release is often associated with volcanic emissions, yet metamorphic carbon production during LIP events may be substantial. Metamorphic carbon devolatilization...
Database for the bedrock geologic map of the Eagle Lake quadrangle, Essex County, New York Database for the bedrock geologic map of the Eagle Lake quadrangle, Essex County, New York
The database for the geology of the 7.5-minute Eagle Lake quadrangle consists of deformed and metamorphosed Mesoproterozoic gneisses of the Adirondack Highlands unconformably overlain by weakly deformed lower Paleozoic sedimentary rocks of the Champlain Valley. The Mesoproterozoic rocks occur on the eastern edge of the Adirondack Highlands and represent an extension of the Grenville...
