Four different geophysical methods were used near Chino Valley, Arizona in
order to map a suspected andesite intrusive, identified as plug 15, which had
originally been found using aeromagnetic data already acquired over the area.
Magnetic, transient electromagnetic, seismic, and gravity measurements were
collected between 3/1/2003-3/2/2003 and 3/22/2003-3/23/2003. The surveys were
located near the center of section 35, township 17 North, Range 2 West, just north of
Chino Valley, AZ. The magnetic and TEM surveys provided the best indication of
the location and depth of the plug. The north-south spatial extent of the plug was
estimated to be approximately 600 meters. The depth to the top of the plug was found
from the TEM survey to be approximately 300 meters at the center of the survey. The
seismic survey did not reach deep enough to find the andesite anomaly and the
gravity survey did not appear to be affected by the plug. Magnetic, TEM, and seismic
surveys were also performed at another site located approximately 1.25 km northeast
of plug 15. The seismic survey did not reach deep enough and the magnetic survey
was too short to provide a depth interpretation. The single TEM sounding measured a
very high resistivity (approximately 900 ohm-m) at this site.
