| Abstract: | Located in： the southern copper-gold metallogenic zone of the ＂ Mianxian-Lueyang- Ningqing＂ triangular mineralized area, the marine altered gold-rich volcano sedimentary formation of the Middle-Upper Proterozoic Bikou Group is widely exposed in Xinchang area. Quartz vein type and structural altered roek type gold deposits are mostly formed at the intersections of ductile shear belts and above superimposed brittle faults, and the multiple phrases of tectonic activities and the formation of fractural systems with different scale and types constituted favorable metallogenic conditions in this area. |
