摘要
Ground current charge, gradient TDIP and TEM integrated geophysics were used in a lead-zinc mine field in northeast Yunnan Province. The authors deduced the I main orebody boundary in southwest, and did some quantitative interpretation. Based on integrated geophysical anomaly, a multiple parallel ore belt on the southeast side of I main orebody was deduced. Geophysical achievement have supplied much important information to blind deposit geologic prospecting, and guided the later mineral exploration and mining work perfectly.
