Application of comprehensive geophysical exploration method in the exploration of Mohar gold polymetallic deposit in Qinghai
On the basis of the collection of geological,mineral,and geophysical exploration result,and the physical characteristics of rocks(ores),high-precision magnetic survey,magnetic profile,and induced polarization gradient measurement method are selected to verify the 1∶25 000 geochemical anomalies in the Mohar area of Qing-hai Province.The result indicates that high-precision magnetic method and induced polarization measurement have the good application effects to identify the structural fracture zone and ultrabasic rock masse.The characteristics of low resistance and high polarization anomalies are indirect prospecting indicators for structural altered rock type poly-metallic deposits,and the high magnetic anomaly area is an ideal target area to search for Cu Ni mining area of mag-ma melting and detachment type.The comprehensive geophysical exploration results have important guiding significance in the exploration of gold polymetallic deposits.
