Repeat Magnetotelluric Transfer Functions from the 2012 Eruption of Tongariro, New Zealand

This dataset consists of 16 repeated magnetotelluric (MT) stations collected on Mount Tongariro, New Zealand, before (2009) and after (2013) the 2012 eruption. The data were collected in same locations with similiar instruments. Preeruption and posteruption electromagnetic magnetotelluric measurements determine variation in subsurface electrical properties resulting from changes in magmatic system

Digital Data for the Preliminary Bedrock Geologic Map of the Blythe 30' x 60' Quadrangle, California and Arizona

This Geologic Map Schema (GeMS) database contains all the geologic map information used to publish the Preliminary Bedrock Geologic Map of the Blythe 30' x 60' Quadrangle, California and Arizona, U.S. Geological Survey Open-File Report 2021-1097. The Blythe 30' x 60' quadrangle in southeastern California and southwestern Arizona displays complex geology that includes Mesozoic contractional deforma

Digital Terrain Model to Support Modeling of Lahars Originating on the West Side of Mount Rainier, Washington

This digital elevation model contains ground surface elevations for the valleys of rivers draining the west side of Mount Rainier, Washington. Elevations are mostly from the 1/9th arc-second (approximately 3 meter) resolution U.S. Geological Survey National Elevation Dataset (NED). The NED data were projected to the Universal Transverse Mercator Zone 10 coordinate system and mosaicked to form a si

Thin section images of hand samples from the Crocodile Lake and Cucumber Lake Intrusions, Duluth Complex, Minnesota

This dataset includes photographic images of thin sections created from hand samples collected from the Crocodile Lake and Cucumber Lake Intrusions, Duluth Complex, Minnesota, along with a shapefile representing the locations of the samples. The samples were collected in order to define copper-nickel-platinum-group element resources associated with the Crocodile Lake and Cucumber Lake Intrusions i

Thin section images of drill core and hand samples from the South Kawishiwi Intrusion, Duluth Complex, Minnesota

This dataset includes photographic images of thin sections created from hand samples and drill core sourced from the South Kawishiwi Intrusion, Duluth Complex, Minnesota, along with two shapefiles representing the locations of the samples and drill hole collars. The samples were collected and core was drilled in order to define copper-nickel-platinum-group element resources associated with the Sou

Magnetotelluric Data from the Gabbs Valley Region, Nevada, 2020

This data set consists of 59 wideband magnetotelluric (MT) stations collected by the U.S. Geological Survey in July and August of 2020 as part of a 1-year project funded by the Energy Resources Program of the U.S. Geological Survey to demonstrate full crustal control on geothermal systems in the Great Basin. Each station had 5 components, 3 orthogonal magnetic induction coils and 2 horizontal orth

USGS Contributions to the Nevada Geothermal Machine Learning Project (DE-FOA-0001956): Heat Flow Data

This package contains a map surface that depicts the estimated spatial variation of conductive heat flow (mW/m?) in a portion of northern Nevada, the extent of the ?Nevada Machine Learning Project? (DE-EE0008762). It was generated using well locations that had an estimated heat flow value from a measured thermal gradient and thermal conductivity, mainly using data from Southern Methodist Universit

USGS Contributions to the Nevada Geothermal Machine Learning Project (DE-FOA-0001956): Slip and Dilation Tendency Data

This package contains data in a portion of northern Nevada, the extent of the ?Nevada Machine Learning Project? (DE-EE0008762). Slip tendency (TS) and dilation tendency (TD) were calculated for the all the faults in the Nevada ML study area. TS is the ratio between the shear components of the stress tensor and the normal components of the stress tensor acting on a fault plane. TD is the ratio of a

USGS Contributions to the Nevada Geothermal Machine Learning Project (DE-FOA-0001956): Geophysics, Heat Flow, Slip and Dilation Tendency

This package contains USGS data contributions to the DOE-funded Nevada Geothermal Machine Learning Project (DE-FOA-0001956), with the objective of developing a machine learning approach to identifying new geothermal systems in the Great Basin. This package contains three major data products (geophysics, heat flow, and fault dilation and slip tendencies) that cover a large portion of northern Nevad

USGS Contributions to the Nevada Geothermal Machine Learning Project (DE-FOA-0001956): Geophysics Data

This package contains gravity and magnetics data and products generated for the Nevada Machine Learning (NVML) project (DE-FOA-0001956). Data products contained in this release consist of grids and vector data. Grids include: primary anomaly maps (isostatic and PSG), match-filtered maps, horizontal gradient (HG) maps, confidence maps, and maps showing density of specific key structural features. T

Density and Magnetic Properties of Selected Rock Samples from the Western U.S. and Alaska

The U.S. Geological Survey (USGS) has collected or incorporated over 20,000 physical property measurements into an ASCII database. These data are primarily from the western U.S. and Alaska and are dominated by granitic rock samples from the Sierra Nevada (compiled by Sikora and others, 1991), but also include a range of other commonly found rocks types. The data include density, magnetic susceptib

High Resolution Gravity and Ground Magnetic Surveys of southern Gabbs Valley, NV

From late 2017 to early 2018, our team collected gravity, ground magnetic (ATV and hiked traverses) and rock property (density and susceptibility) data in southern Gabbs Valley in west-central Nevada.
