Geochemical and Geochronological Data for Hydrothermal Systems on Brokeoff Volcano and in the Maidu Volcanic Center, Lassen Peak area, northeastern California
This dataset contains 8 data tables provided in csv format that contain sample location data, whole-rock geochemical data, argon-argon geochronologic data, sulfur, oxygen, and hydrogen isotope data, and mineralogical data from shortwave infrared spectrography (SWIR) and X-ray diffraction (XRD) analyses collected from igneous rocks on Brokeoff and Maidu volcanoes, northeastern California, USA. The
Airborne electromagnetic and magnetic survey data, Stillwater Complex, Montana, May 2000
A helicopter-borne electromagnetic/magnetic survey was flown over the Stillwater area, southwest Montana from May 5 to May 16, 2000. The survey was conducted over the Stillwater Igneous Complex, a Precambrian layered mafic-ultramafic intrusion which is characterized by igneous layering. Electromagnetic data were acquired using DIGHEM helicopter-borne electromagnetic system. Magnetic data were coll
Digitized sonic velocity log data of the Sacramento Delta region, California
The datasets consist of basic well information and of digitized sonic velocity data from commercially run well logs in the Sacramento Delta region, California.
High-Resolution Aeromagnetic Survey of Mountain Pass, California
A detailed aeromagnetic survey of Mountain Pass, California was flown by CGG Canada Services Ltd. (CGG) during November and December, 2016. The high-resolution helicopter survey was flown at a flightline spacing of 100 and 200 m, a flightline azimuthal direction of 70 degrees, a nominal flightline elevation above ground of 70 m, and consists of about 1,814 line-kilometers. Tie lines were spaced at
Geophysical datasets for the FORGE Fallon site
The datasets include geophysical and rock property measurements and models accompanying the FORGE Fallon Phase II study
Database of significant deposits of gold, silver, copper, lead, and zinc in Alaska
This data release provides descriptions and locations of 134 significant deposits in Alaska. Approximately 99 percent of past production and remaining identified resources of gold, silver, copper, lead, and zinc in the United States are accounted for by deposits that originally contained at least 2 metric tons (t) of gold, 85 t silver, 50,000 t copper, 30,000 t lead, and 50,000 t zinc. Deposits of
Rare Earth Element Occurrence Database of the Tien Shan Region, Central Asia
Central Asia, site of the historic Silk Road trade network, has long been a conduit for the movement of people, energy, and mineral resources between Europe and Asia. Once part of the former Soviet Union, this region was and continues to be an important producer of base and precious metals, rare metals (RM), including niobium, tantalum, and beryllium, and a past producer of rare earth elements (RE
Titanium-vanadium deposits hosted in mafic-ultramafic layered intrusions and massif anorthosite intrusions from around the world
This data release includes four .csv files and one Esri shapefile which contain data on titanium-vanadium deposits hosted in mafic-ultramafic layered intrusions and massif anorthosite intrusions from around the world. Some of the data was used to create a grade and tonnage model for titanium-vanadium deposits hosted in mafic-ultramafic layered intrusions. Only deposits with reported grade and tonn
Previous mineral resource assessment data compilation for the U.S. Geological Survey Sagebrush Mineral Resource Assessment Project
This data release consists of a compilation of previously published mineral potential maps that were used for the Sagebrush Mineral Resource Assessment (SaMiRA) project. This information was used as guides for assessing mineral potential assessment of approximately 10 million acres in Idaho, Montana, Nevada, Utah, and Wyoming. Specifically, the compilation was used to identify the deposit types to
Missouri Breaks Project, Montana - Digitized aeromagnetic data
From February 12 to March 8, 1981, EG and G Geometrics conducted an aeromagnetic survey in Montana for Anaconda Copper Company. A Piper Navajo aircraft was used to conducted the survey. The survey was flown along north-south flightlines spaced 660 feet at a nominal height of 450 feet above the terrain. Five uniformly spaced east-west tie-lines were also flown. During processing, the International
