Abstract

logy in Korean geologic environment, test airborne geophysical surveys were conducted over a known uranium deposit using two AEM systems; GSA’s frequency domain loop-loop EM system and time domain EM system with grounded electrical source (GREATEM system). The main geologic feature of the test site is the phyllite formation with uranium mineralization in a graphitic zone and AEM surveys by two systems successfully delineated the graphitic conductors in this site. Considering the field condition with tough topographic variation, GREATEM system seems to have better performance in terms of data acquisition and depth of investigation, while GSA’ system provides better resolution for shallow subsurface structures, which is due to underlying EM principles used in the two systems. By this comparative study, we could convince that AEM technology is a very effective tool to the exploration of mineralized zone in Korean geologic environment.
