摘要
Based on geological background of As117-3 survey area in the Xizang Dagou gold deposit, Qinghai Province, geophysical and geochemical explorations for ore prospecting are conducted. Two large prospecting abnormity areas,AP1 and AP2,are found after measurements of 1:50 000 stream sediment survey,1:10 000 soil geochemistry survey and induced polarization. Reconnaissance testing by surface trough and deep tunnel in the AP1 target indicated that this mineralizing area had the feature of the gold content gradually growing with the prospecting depth.
