Magnetic susceptibility and gamma ray spectrometry measurements in southwestern Montana, 2023-2024
Description
This dataset includes rock magnetic susceptibility and gamma ray spectrometer measurements from 243 outcrops in southwest Montana during 2023-2024. The measurements were collected to understand the causative sources of airborne magnetic and radiometric survey anomalies in the Idaho-Montana porphyry belt. Sixteen magnetic susceptibility measurements were collected at each analyzed site using a ZH Instruments SM30 susceptibility meter. Gamma ray measurements were collected using a Radiation Solutions RS-230 BGO Super-SPEC Handheld Gamma-Ray Spectrometer. Geologic units were assigned from 1:100,000 scale digital geologic maps noted in the supplemental information section of the metadata file.
