Fixed-loop TEM surveying using the SQUID magnetometer for deep mineral exploration in a conductive area

Abstract The Baiyun gold deposits in the Qingchengzi ore concentration area have significant deep exploration potential. Transient electromagnetic (TEM) is conducted to identify ore-bearing strata and ore-controlling structures mining area’s periphery. Previous tests revealed that it challenging penetrate conductive layer obtain information using a conventional in-loop TEM method with an induction coil. Field data are acquired high-temperature superconductor (HTS) superconductive quantum interference device (SQUID) magnetometer fixed-loop configuration. results indicate SQUID system can detect distribution of strata, ore-control within formations. paper explores two extension areas east west thrust nappe structural belt. inversion reveal deposit significantly compressed, noticeable thrusts faults. Since fault zone extends south stably, lower section has gentle dip angle favorable for prospecting.
