In December of 2018, the U.S. Geological Survey (USGS) signed a Technical Assistance Agreement with a third party to reanalyze 2,324 archived sample splits collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) project from selected areas in Idaho and Montana. A small amount (approximately 0.25 grams [g]) of sieved <75-micron sample material was retrieved from the USGS National Geochemical Sample Archive for geochemical analysis. These samples were analyzed for 48 elements by ALS Global laboratories using their ultra-trace four-acid-digestion dual-mode inductively coupled plasma mass spectrometry (ICPMS) (ALS ME-MS61L) method (Ag, Al, As, Ba,...

The Geochemical Database for Iron Oxide-Copper-Cobalt-Gold-Rare Earth Element Deposits of Southeast Missouri (IOCG-REE_GX) contains new geochemical data compilations for samples from IOCG-REE type deposits in which each rock sample has one "best value" determination for each analyzed species, greatly improving speed and efficiency of use. IOCG-REE_GX was created and designed to compile whole-rock and trace element data from southeast Missouri in order to facilitate petrologic studies, mineral resource assessments, and the definition and statistics of geochemical baseline values. This relational database serves as a data archive in support of present and future geologic and geochemical studies of IOCG-REE type deposits,...

The geochemical data included here were generated as part of a Technical Assistance Agreement between the U.S. Geological Survey (USGS) and Rio Tinto Exploration based in Salt Lake City, Utah. Beginning in November of 2015, we began a project to reanalyze up to 60,000 archived sample splits originally collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) project from selected areas in Arizona, California, Idaho, Montana, Nevada, New Mexico, and Utah. A small amount (approximately 0.25 g) of sieved <75 micron sample material was retrieved from the USGS National Geochemical Sample Archive for geochemical analysis. These samples were analyzed...

Selected archived sample splits collected as part of the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) program, were reanalyzed by the U.S. Geological Survey (USGS) as part of a NURE-HSSR Reanalysis project (Smith and others, 2018). A small amount (approximately 0.25 grams [g]) of sieved less than 75-micron sample material was retrieved from the USGS National Geochemical Sample Archive for geochemical analysis. These samples were analyzed for 51 elements under a Technical Assistance Agreement with a third party by ALS Global laboratories using their ultra-trace four-acid-digestion dual-mode inductively coupled plasma-optical emission spectrometry/mass spectrometry...
Note: This data release is currently being revised and is temporarily unavailable. The data release for the Idaho Primitive Area, including the contiguous, Clear Creek-Upper Big Deer Creek Area, Salmon River Breaks Primitive Area, the Sawtooth Primitive Area, and adjacent areas, central Idaho, contains a data set of previously unpublished geochemical data from the 1966-1984 projects. The purpose of the Primitive Area studies was to describe the geology, determine petrologic and geochemical characteristics and to evaluate the mineral resource potential of the primitive areas and of adjacent study areas. In the case of the Idaho Primitive Area study (Cater and all, 1973), the primitive area and adjacent study areas...

The data release for Gospel-Hump Wilderness Area and the Magruder Corridor and Special Mining Management Zone Additions to the Frank Church River of No Return Wilderness Area, and adjacent areas Idaho and Montana, contains a subset of previously unpublished geochemical data from the 1979-1984 projects. In the case of Gospel-Hump Wilderness Area study (Lund and Esparza, 1990), the purpose of the project was to determine petrologic and geochemical characteristics and to investigate effects of historic mine drainage in the study area. Data for the Magruder Corridor Addition reflect rock geochemistry to document petrologic and geochemical characteristics (Mosier and others, 1981; Lund and others, 1992). Included in...
The geochemical data included here were generated as part of the Earth Mapping Resources Initiative (Earth MRI), which was developed by the U.S. Geological Survey (USGS) in response to a Federal directive calling on various Federal agencies to address potential vulnerabilities in the Nation’s supply of critical mineral resources. Earth MRI is a partnership between the USGS, State Geological Surveys, and industry coordinating with other federal agencies to accomplish the mission. The primary purpose of this initiative is to identify potentially mineralized areas containing critical minerals by gathering new basic geologic data about the United States and its territories and to make these data publicly available through...

The Geochemical and geologic database for Mesoproterozoic igneous rocks and iron oxide-apatite-rare earth element (IOA-REE) and iron oxide-copper-cobalt-gold (IOCG) deposits of Southeast Missouri, 2016-2017 'Geochemical Database for Iron Oxide-Copper-Cobalt-Gold-Rare Earth Element Deposits of Southeast Missouri, 2016-2017' (MO_ROCK_IOCG_REE_GX2017) contains new geochemical data compilations for samples from Mesoproterozoic igneous rocks and iron oxide deposits of the Precambrian basement of southeast Missouri. Each sample has one "best value" determination for each analyzed species, greatly improving speed and efficiency of use. MO_ROCK_IOCG_REE_GX2017 was created and designed to compile whole-rock and trace element...

The Global Geochemical Database for Critical Metals in Black Shales (CMIBS) contains new geochemical data compilations for fine-grained sedimentary rocks in which each geologic material sample has one 'best value' determination for each analyzed species, greatly improving speed and efficiency of use (Granitto and others, 2013). The CMIBS was created and designed to compile and integrate geochemical data from seven continents in order to facilitate petrologic studies, mineral resource assessments and mineral exploration, definition of geochemical baseline values and statistics, environmental impact assessments, paleobiological studies and paleoenvironmental trends through Earth history. and studies in human health...

The Alaska Geochemical Database Version 3.0 (AGDB3) contains new geochemical data compilations in which each geologic material sample has one best value determination for each analyzed species, greatly improving speed and efficiency of use. Like the Alaska Geochemical Database Version 2.0 before it, the AGDB3 was created and designed to compile and integrate geochemical data from Alaska to facilitate geologic mapping, petrologic studies, mineral resource assessments, definition of geochemical baseline values and statistics, element concentrations and associations, environmental impact assessments, and studies in public health associated with geology. This relational database, created from databases and published...

This data release provides multi-element data for drill core samples from the Mesoproterozoic Nonesuch Formation and Copper Harbor Conglomerate at the Copperwood copper deposit, Michigan, USA. Gold, platinum, and palladium data were collected by fire assay; copper and silver were collected by assay; and other elements were collected by inductively coupled plasma-optical emission spectrometry (ICP-OES) or inductively coupled plasma-mass spectrometry (ICP-MS) following a digestion that used hydrochloric, nitric, perchloric and hydrofluoric acids. The Copperwood copper deposit is a sediment-hosted stratiform copper deposit in the Presque Isle Syncline of the upper peninsula of Michigan. The deposit has a 2018 mineral...
