Abstract: There are clear Au, As, Sb and Hg showings in geochemical exploration and anomaly investigation in the eastern section of the northern margin in the South Qilian mineralization belt.However, the prospecting has not achieved breakt hrough in the area in the past.Through synthetic studies of mineralization setting, geochemical anomalies and known ore deposits as well as other factors in the area, this paper argues that ore-forming conditions are favorable for gold and thus the area has great potential for mineral recourse.Also, we suggest that geological investigation and prospecting for Au(Sb) should be carried out further.The targetareas will be the Gangchadasi, the Larenwaerma-Larenxiuma areas where the similar ore-forming setting has been expected.
