Geophysical surveys were conducted in the Pima mining district by
students from the University of Arizona. The surveys were concentrated
along section B-B' from Cooper (1973). The objectives of
this survey included: teaching geophysical techniques, mapping
regional structure along this profile, and determining which geophysical
techniques were most useful for regional .mapping in this
area. Controlled source audio-frequency magnetotelluric (CSAMT)
surveys successfully mapped depth to basement along this profile.
Seismic refraction surveys were not able to map depth to basement.
Either the depth to basement was beyond the range of the
arrays used in this experiment or there is insufficient contrast
in the velocity between the basement and the overlying rocks. A
test of the seismic reflection method was carried out using a
walk-away noise spread. Possible reflections from basement were
noted but were not sufficiently diagnostic to be routinely use able.
