Summary

Controlled source audio-frequency magnetotellurics (CSAMT) data were collected in the Big Chino Valley and Paulden areas, Yavapai County, Arizona, 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. Data were collected using a GGT-30 transmitter and GDP32-II receiver (Zonge international. Inc.). Data processing and inversions were carried [...]

Purpose

Data were collected to aid the interpretation of hydrogeology, including formation boundaries and fault locations, in the Paulden and Big Chino region of Yavapai County, Arizona. Station data are provided for plotting and testing alternative geophysical inversion schemes.
