Abstract: The Taqian-Fuchun ore concentrated area was recently discovered to host a Cu-polymetallic mineralized alteration zone at Sicun. Comparison study of the Sicun mineralized alteration zone with the large-sized Zhuxi W-Cu polymetallic deposit in geology, mineralization, alteration, and geophysical-geochemical-remote sensing anomalies indicates that the Sicun area has similar minerogenetic geological condition as the Zhuxi deposit. According to the geological characteristics of diorite porphyrite, lamprophyre, and gabbro-dolerite dykes in the Sicun area, we can infer existence of granitoids at depth. Combined with the late Paleozoic carbonate rocks, faulting zones, and interlaminar fractures, it can be speculated that uprising granitic magma etasomatized carbonatic rocks, forming skarn-type deposits or hydrothermal vein-type deposits, both of which may have relatively great potential for mineralization. Therefore, the next prospecting target should focus on the contact zone between intrusive rock and carbonatic rock, fracture zone and interlayer fracture zone.
