Summary

This data release provides digital flight line data for a high-resolution airborne radiometric survey over parts of Montana in the vicinity of the Boulder Batholith. The airborne survey was jointly funded by the Earth Mapping Resources Initiative and Kennecott Exploration Company. The survey was designed to meet complementary needs related to geologic mapping and characterization of mineral resource potential. A total of 34,041 line km of magnetic and radiometric data were acquired over an irregular-shaped area of 6178 km2. Data were collected from a helicopter flown at a nominal terrain clearance of 100 meters (m) above topography along E-W flight lines spaced at 200 m intervals. Tie lines were flown in an N-S direction every 2000 [...]

Purpose

Data was collected as part of the Earth Mapping Resource Initiative (Earth MRI) program of the U.S. Geological Survey (USGS) in collaboration with Kennecott Exploration Company to better understand the geology and critical mineral resources in the area. The primary goal of the airborne magnetic and radiometric survey is to map lateral variations of magnetization and natural radioactivity that are related to differences in rock and soil type, and to aid surface and subsurface geologic mapping.
