Airborne geophysical surveys were conducted in the eastern Adirondacks from Dec. 7, 2015 - Dec. 21, 2015, by Goldak Airborne Surveys. The area was flown along a draped surface with a nominal survey height above ground of 200 meters. The flight line spacing was 250 meters for traverse lines and 2500 meters for control lines. Here we present downloadable magnetic and radiometric (gamma spectrometry) data from those surveys as image (Geotiff) and flight line data (csv format). Background The Eastern Adirondacks region was known for iron mining in the 1800's and 1900's but it also contains deposits of rare earth minerals. Rare earth minerals are used in advanced technology such as in cell phones, rechargeable batteries...

Thirty-four ore, twenty-nine mine waste, seven host rock, two pegmatite, and one slag sample were collected from iron oxide-apatite (IOA) mines in the eastern Adirondack Highlands near Mineville and Ticonderoga, New York, from March 2016 to August 2018. The waste pile samples included twenty-five samples collected from rubble-sized mine waste piles and four samples from processed tailings piles. The ore from historic iron mines of the eastern Adirondack Highlands, New York, contain abundant quantities of rare earth element (REE)-bearing apatite crystals. These apatite crystals are especially enriched in Y, La, Ce, and Nd. In-ground ore, mine waste piles, and tailings piles could contain apatite...

Airborne magnetic gradiometry data are provided here as part of the data release, "Airborne magnetic and radiometric survey, Columbia, South Carolina and surrounds, 2020." This website includes the processed aeromagnetic data provided in an ascii .csv file and a geoTIFF image showing the magnetic field intensity. The contractor report is available on the parent page. These data were collected as part of a high-resolution airborne magnetic and radiometric survey over Columbia, South Carolina and the surrounding region immediately northwest of an airborne magnetic and radiometric survey collected near Charleston, South Carolina in 2019 (Shah, 2020). Goals included imaging heavy mineral sands containing titanium,...

Airborne magnetic surveys were conducted in Oklahoma from August 11th, 2017-October 28th, 2017, by Goldak Airborne Surveys. Here we present downloadable flight line data from those surveys in comma-separated values (csv format). Three areas were flown along a draped surface with a nominal survey height above ground of 120 meters. The flight line spacing for these areas was 200 to 400 m for Area 123, in southwestern Oklahoma; 1000 m for Area 4, in northwestern Oklahoma, and 800 m for Area 5, in north-central Oklahoma. For each area control lines were flown at ten times the traverse line spacing. The surveys were flown to map subsurface geologic variations including ancient magmatic bodies, faults, and other geologic...

Airborne Geophysical Surveys over the 2011 Mineral, Virginia, Earthquake Area The 2011 moment magnitude (Mw) 5.8 central Virginia earthquake was felt by millions of people and caused significant damage in the eastern United States. As part of efforts to better understand the faults and geologic features associated with the earthquake, the U.S. Geological Survey commissioned airborne geophysical surveys over the epicentral area. Here we present the data from those surveys and summarize research results based on those datasets. The following items can be obtained by following links on this page: - Background information on the Mineral, Virginia earthquake and a summary of first analysis results - Downloadable...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over Virginia and North Carolina along and near the eastern U.S. 'Fall Zone', which represents the transitional area between Atlantic Coastal Plain sediments and Piedmont metamorphic and igneous rocks. The airborne data collection was funded by the U.S. Geological Survey (USGS) Earth Mapping Resources Initiative (Earth MRI) and National Cooperative Geological Mapping Program (NCGMP). Goals include a gaining a better understanding of placer deposits containing critical mineral resources titanium, zirconium, and rare earth elements, assisting geologic mapping of the crystalline basement either exposed...

Airborne radiometric data are provided here as part of the data release "Airborne magnetic and radiometric survey, Columbia, South Carolina and surrounds, 2020." This website includes the processed aeroradiometric data (gamma spectrometry for K, U and Th) provided in an ascii .csv file, spectral data in a binary netcdf file that can be read using the relevant Python libraries (see example included with this release), and a geoTIFF showing a ternary image of the K, Th, and U channels. The contractor report is available on the parent page. These data were collected as part of a high-resolution airborne magnetic and radiometric survey over Columbia, South Carolina and the surrounding region immediately northwest...

This website provides digitized shapefiles representing surface geologic features depicted in Matthew S. Walton's unpublished 1960 geologic map of the Elizabethtown quadrangle, Essex County, New York. Features represented by these files include geologic units representing Precambrian basement rock, geologic structures, diabase dikes, mine shaft locations, and water bodies. The shape files in this data release represent Walton's original field observations and interpretations. Walton's detailed notes and a georegistered geotiff image of the original map are also included.

In response to Executive Order 13817 of December 20, 2017, the U.S. Geological Survey (USGS) coordinated with the Bureau of Land Management (BLM) to identify 35 nonfuel minerals or mineral materials considered critical to the economic and national security of the United States (U.S.). Acquiring information on possible domestic sources of these critical minerals is the basis of the USGS Earth Mapping Resources Initiative (Earth MRI). The program, which partners the USGS with State Geological Surveys, federal agencies, and the private sector, aims to collect new geological, geophysical, and topographic (lidar) data in key areas of the U.S. to stimulate mineral exploration and production of critical minerals. The first...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over Columbia, South Carolina, and the surrounding region. The airborne data collection was funded by the U.S. Geological Survey (USGS) Earth Mapping Resource Initiative (Earth MRI) with goals of better understanding placer deposits containing critical mineral resources titanium, zirconium, and rare earth elements and of imaging the crystalline basement partly buried beneath Atlantic Coastal Plain sediments. The survey was flown northwest of and slightly overlapping an airborne magnetic and radiometric survey collected in 2019 (Shah, 2020). The northwestern boundary of the 2020 survey lies within the...

This data release provides digital flight line data for a high-resolution airborne magnetic and radiometric survey over parts of northern Maine. The airborne data collection was funded by the U.S. Geological Survey (USGS) Earth Mapping Resource Initiative (Earth MRI) with goals of better understanding volcanogenic massive sulfide mineral deposits, sediment hosted manganese deposits, and their surrounding geologic framework. Data for this survey were collected and processed by Sander Geophysics under contract with the USGS. The airborne survey took place June-July 2021. Using a fixed wing aircraft with a magnetometer mounted in a tail stinger and a fully calibrated gamma ray spectrometer, data were collected along...
