Arizona gravity and aeromag maps posted online

AZGS has posted two classic statewide geophysical maps at our online document repository for free downloading:

Residual Aeromagnetic Map of Arizona 

Residual magnetic intensity values are given in gammas. The original total field data were corrected for diurnal variation as observed at the Tucson Magnetic Observatory during the flight period.

Residual Bouguer Gravity Map of Arizona  

Gravity data were obtained from surveys by the Laboratory of Geophysics of the University of Arizona, U.S. Defense Mapping Agency, U.S. Geological Survey, Exxon Corporation, and mining companies and contractors.
