Airborne magnetic and radiometric survey, southeastern Illinois, western Kentucky, and southern Indiana, 2019 Airborne magnetic and radiometric survey, southeastern Illinois, western Kentucky, and southern Indiana, 2019
Note: this data release has been superseded by version 2.0, available here: https://doi.org/10.5066/P14PJFWS. This publication provides digital flight line data for a high-resolution magnetic and radiometric survey over an area of southeast Illinois, western Kentucky, and southern Indiana. The survey includes airborne geophysical data collected as part of the U.S. Geological Survey (USGS...
High Resolution Aeromagnetic Survey, Villa Grove, Colorado, USA, 2011 High Resolution Aeromagnetic Survey, Villa Grove, Colorado, USA, 2011
This data release includes data collected from the Villa Grove helicopter magnetic survey in northern San Luis Valley and Poncha Pass region in south-central Colorado, USA. The survey area extends over the northern part of Great Sand Dunes National Park, Poncha Pass and vicinity, and into the southern end of the Upper Arkansas Valley. It includes the communities of Crestone, Villa Grove...
Audiomagnetotelluric data, Buffalo River watershed, Arkansas, 2017 Audiomagnetotelluric data, Buffalo River watershed, Arkansas, 2017
This dataset includes the locations for audio-magnetotelluric (AMT) sounding data collected in August 2017 in the Buffalo River watershed of northern Arkansas by the U.S. Geological Survey (USGS). The sites were mostly alongside Osage Creek and its intermittent tributaries. Along with geologic mapping, the USGS used AMT data at 6 sites along a southwest-northeast profile of about 7...
Audiomagnetotelluric sounding data in the Silverton Caldera complex, Colorado, 2018 Audiomagnetotelluric sounding data in the Silverton Caldera complex, Colorado, 2018
This data release includes audiomagnetotelluric (AMT) sounding data collected in July 2018 in the Silverton Caldera complex, Colorado, in the Southern Rocky Mountain Volcanic Field, by the U.S. Geological Survey (USGS). Along with geologic mapping, airborne magnetics, airborne electromagnetics, and magnetotellurics, the USGS collected AMT data at 24 sites along four profiles ranging from...
Audiomagnetotelluric sounding data, stations 1-9, Taos Plateau Volcanic Field, New Mexico, 2009 Audiomagnetotelluric sounding data, stations 1-9, Taos Plateau Volcanic Field, New Mexico, 2009
This dataset includes the audio-magnetotelluric (AMT) sounding data collected in 2009 in and near the San Luis Basin, New Mexico. The U.S. Geological Survey conducted a series of multidisciplinary studies, including AMT surveys, in the San Luis Basin to improve understanding of the hydrogeology of the Santa Fe Group and the nature of the sedimentary deposits comprising the principal...
Magnetotelluric sounding data, stations 1 to 12, East-Central Tooele County, Utah, 2003 Magnetotelluric sounding data, stations 1 to 12, East-Central Tooele County, Utah, 2003
This dataset includes the magnetotelluric (MT) sounding data collected in 2003 along a north-south profile west of Tooele, Utah. It is important to know whether major mining districts in the Northern Nevada Gold Province are underlain by rocks of the Archean Wyoming craton, which are known to contain orogenic gold deposits, or by accreted rocks of the Paleoproterozoic Mojave province. It...
Airborne Magnetic Total-Field Survey, Manchester Region, Iowa, USA Airborne Magnetic Total-Field Survey, Manchester Region, Iowa, USA
This data release includes the airborne magnetic survey data collected from the Manchester region of Iowa. The Mineral Resources Program of the U.S. Geological Survey is tasked with understanding the nation's mineral resources. Precambrian rocks concealed under Paleozoic sedimentary rocks in northeast Iowa are poorly mapped and understood. Detailed high-resolution airborne magnetic...
