GEOPHYSICAL AND GEOCHEMICAL CHARACTERISTICS AND GOLD-SILVER POLYMETALLIC METALLOGENIC CONDITIONS IN AHADAWA AREA, QINGHAI PROVINCE

The study area is located in the southeast margin of Qaidam Basin, tectonically belonging to the northern Qaidam ophiolite melange zone. Based on the comprehensive study of metallogenic geological setting, geophysical and geochemical characteristics, and comparison with the neighboring Saibagou gold deposit, it is concluded that the study area has advantaged metallogenic background and well geophysical and geochemical anomalies, with similar metallogenic background to Saibagou gold deposit. There are favorable metallogenic conditions for tectonic altered rock type of gold polymetallic deposit and hydrothermal filling deposit prospecting in the area.
