Application of Integrated Geophysical Methods to a Molybdenum Polymetallic Deposit in the Tibetan Plateau

The Tibetan plateau is a natural laboratory for geologists,which plays host to abundant non-ferrous metal reserves.However,the harsh climate made the limits studies in this area.This paper presents exploration results of integrated geophysical methods at a molybdenum polymetallic deposit in the Tibetan plateau.Based on the regional geology,strata,structure and magmatic rocks,this paper introduces the chosen geophysical methods in the area,including dual-frequency IP precision measurement profile and AMT sounding in some special areas.In combination with the dual-frequency IP precision measurement profile,we interpreted the AMT sounding profiles.At the drill holes penetrating mineralization intervals,induced logging has also been carried out.Then,a geological and geophysical model for the prediction of the mineralization intervals was established. The molybdenum fine-grained granites which are closely related to mineralization were delineated,the burial depth and trends of the anomalous bodies were determined,and some fault zones were confirmed.In the late stage,test drill holes were deployed and attained appreciable ore-search results.This work may provide a valuable prospecting experience for the future exploration in the Tibetan plateau.
