Controlled source audio-frequency magnetotellurics (CSAMT) data from the Sevier Fault near Red Knoll, Kane County, Utah - Inversion Data (ver 2.0, July 2022)

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2020-08-07T00:00:00Z
Controlled source audio-frequency magnetotellurics (CSAMT) data were collected over the Sevier fault, near Red Knoll in Kane County Utah, to better understand the hydrogeology of the area. CSAMT data provide vertical cross-section (profile) data about the resistivity of the subsurface, which may be related to lithologic boundaries and (or) grain-size distribution in the subsurface. CSAMT involves transmitting a current at various frequencies in one location, and measuring resistivity differences between electrodes spaced along a receiver line several kilometers from the transmitter. Sevier_fault_CSAMT_InversionData.zip: Text files of inverted resistivity values, starting model values, and corresponding x, y, z coordinates. These files allow the user to recreate the inversions provided in the accompanying .jpg file. The zip file contains one text file per line.
