Data

This dataset contains a 6‑class soils map (30-meter) for the Los Planes basin in Baja California Sur, Mexico. The map was generated using a digital soil mapping approach that incorporates environmental covariables following the SCORPAN (soil, climate, organisms, topography, parent material, age, and time) framework. The data release also includes a point feature class representing...

This dataset consists of one table containing whole-rock geochemistry data for 250 igneous and metamorphic rocks from the Darby Mountains area on the Seward Peninsula in western Alaska, collected in 2017. All materials were analyzed by ALS Global, between 2019 and 2020, by a range of different techniques; multiple unique entries for a given element relate to different analytical methods...

Geothermal springs may be connected to both shallow and deep groundwater sources, and identification of variable spring sources may assist with resource management of geothermal systems. Numerous geothermal springs exist near the Yampa River in Steamboat Springs, Colorado and local water and land management agencies could benefit from information on the sources of these springs. This...

Geochemical data reported here were collected on samples from the USGS Gulf Coast 2 (GC-2) core that was drilled near Dallas, TX, representing a proximal location of the Eagle Ford Group. These data were collected to better characterize the properties and variability within the Eagle Ford Group, an important and prolific petroleum source rock unit. This data accompanies a manuscript that...

The National Crude Oil Spill Fate and Natural Attenuation Research Site near Bemidji, Minnesota is the site of a 1979 high-pressure crude oil pipeline rupture. Approximately 1.7 million liters of crude oil spilled onto the glacial outwash aquifer. After remediation and natural attenuation, an estimated 25% of the oil remains in the subsurface today. Groundwater monitoring at the site...

This release of whole-rock geochemical data for northwestern Utah and adjacent Idaho and Nevada is for unaltered intrusive rocks sampled and analyzed from 1980 to 2023. The rocks range in age from Archean to Cenozoic. Most samples represent plutons, stocks, and dikes of Mesozoic and Cenozoic age. A few older igneous and metamorphic rocks are included. The data support several map...

In 2024, the U.S. Geological Survey, in cooperation with Riverside Energy Michigan, LLC, conducted an injection experiment to assess the potential for stimulating biogenic methane in the Mortensen A4-24 well which was completed in the Antrim Shale and located in Antrim County, Michigan, United States of America. Approximately 20 barrels (bbl) of produced water was pumped from the well...

The data set contains geochemical data for 1,524,014 rock, sediment, soil, and mineral samples collected by the U.S. Geological Survey within US state, territory or Economic Exclusive Zone (EEZ) boundaries, and analyzed from 1962 through 2023 either in the analytical laboratories of the Geologic Discipline of the USGS or by contract with commercial analytical laboratories. These data...

Geochemical data were generated and compiled for sedimentary rocks and bentonites deposited in the Cretaceous Western Interior Seaway from 15 drill cores and 1 outcrop spanning present-day Texas to Alaska. These data were collected to better understand Cretaceous source rocks and petroleum systems of the United States. These data accompany a manuscript that will be submitted to a journal...

This data release comprises major and trace element geochemical data from ninety (90) selected bedrock samples in support of the identification, discrimination, and correlation of map units in the Deep River and Essex quadrangles, Middlesex County, Connecticut. In data tables, the attributes “map_unit_symbol” and "map_unit_name" correlate the sample to the map unit in a planned bedrock...

This U.S. Geological Survey (USGS) data release contains data from stream water and groundwater samples collected in July through October 2024 at the Perigo Mine site in Gilpin County, northern Colorado. Data were collected as part of a study aimed at characterizing the local groundwater flow system in the hillslope hosting the mine’s draining crosscut tunnel, and identifying sources of...

Hydrothermal manganese oxide rocks were collected via dredge from the Tulaga Seamount, the flank of Ofu Island, and from Soso seamount in the Samoa hotspot region offshore American Samoa during the KM0506 cruise aboard the R/V Kilo Moana in April of 2005. Rocks were subsampled at USGS and analyzed for mineralogy by x-ray diffraction as well as sent to SGS laboratories, Canada for major...
