Data

Geochemical, petrophysical, and depth to the Paleozoic-Precambrian basement interface from drill hole data for Mesoproterozoic igneous rocks and iron ore deposits of the St. Francois Mountains, southeast Missouri (MMDB) are provided in this data release. The samples were collected as part of various agency programs and projects from 1967 through 2019. Most samples were collected by agency personne

Stable isotope analyses are reported (the ratios deuterium/hydrogen, carbon-13/carbon-12, oxygen-18/oxygen-16, and sulfur-34/sulfur-32) for ores and related rocks from the Pea Ridge, Lower Pilot Knob, Bourbon, Iron Mountain, and Kratz Spring iron oxide-apatite deposits in southeast Missouri; the Boss iron oxide-copper-gold deposit in southeast Missouri; the Gagaryah stratiform barite deposit in Al

Powder X-ray diffraction (XRD) data and estimates of mineral abundances determined using Rietveld refinement included in this data release were generated as part of the Earth Mapping Resources Initiative (Earth MRI; https://www.usgs.gov/special-topics/earth-mri). Earth MRI is a partnership between the U.S. Geological Survey (USGS) and state geological surveys and was developed by the USGS to evalu

Gravity data were collected in 2022 and 2023 to assist in mapping surface and subsurface geology in the central Upper Peninsula of Michigan. This data release provides principal facts for 666 new gravity stations that were acquired to supplement existing public gravity data coverage.

The U.S. Geological Survey (USGS) collected rock physical property measurements to help understand causative sources of gravity and magnetic survey anomalies in the central Upper Peninsula of Michigan. A total of 1,460 measurements of magnetic susceptibility and density from 61 outcrops and 37 boreholes have been conducted on Precambrian rocks. The measurements aid in interpretation of gravity and

This dataset accompanies proposed publication, "Tectonic disruption of the Proterozoic Yavapai-Matzatzal Province boundary near Sierra Hornaday, northwest Sonora", to be published in a Geological Society of America publication, which will report zircon SHRIMP-RG U-Pb ages and Sm-Nd whole rock isotope analyses to map the path of the Yavapai-Matzatzal province boundary across southwest Arizona and n

This dataset consists of seven lava samples that were analyzed for Pb, Sr, and Nd isotopes. The dataset accompanies the planned publication, ‘The geochemical and petrogenetic evolution of Þingmúli central volcano: Insights to magma processes in Iceland’, as well as planned future publications on this volcanic complex. Pb, Sr, and Nd isotope data were used for this study to determine both the mant

These U-Pb zircon geochronology and whole rock geochemistry data were collected as part of a bilateral campaign of the U.S. Geological Survey (USGS) with the Uzbekistan Ministry of Mining, Industry, and Geology (MinGeology; formerly GOSCOMGeology) to support a new quantitative/qualitative mineral resource assessment for tungsten, gold, rare-earth elements, graphite, and uranium in the Auminzatau a

Pegmatites are a major host of global lithium, cesium, and rubidium resources. However, the existing grade and tonnage dataset for lithium pegmatites that was published in 1992 does not represent the current industry parameters used to delineate resources. There are no existing grade and tonnage datasets for cesium and rubidium. We present grade and tonnage data for lithium, cesium, and rubidium m

The southern margin of the Archean Superior Province in the central Upper Peninsula of Michigan records Paleoproterozoic tectonic events involved in the ~2.1 Ga rifting of the proposed Archean supercraton Superia and the subsequent assembly of Laurentia. Within a small area of Dickinson County, Michigan, there are many distinctive geologic units with confounding structural and stratigraphic relati

This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of the White Rock Canyon quadrangle, Carbon County, Wyoming (Hyden and others, 1968). 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 USGS Geologic Quadrangle Map GQ-789. The

Critical minerals are essential for the energy transition; to meet sustainability goals, production of these resources must significantly increase within the coming decades. For example, demand for lithium, an element essential for battery technologies found in many electronics and vehicles, is anticipated to increase by more than ten-fold by 2050 compared to current production. Critical minerals
