摘要: 南祁连成矿带北缘东段区域地球化学扫面及异常查证均有较好的Au、As、Sb、Hg组合异常显示,但该区金矿找矿工作多年来一直未能取得突破性进展.通过对该区成矿地质环境、地球化学异常和已有成矿事实等因素分析,认为该区金矿成矿地质环境有利,具有进一步扩大资源量的潜力和前景,建议对该区进一步开展以寻找Au(Sb)矿为目的普查找矿工作.同时,应对该区带具有相似金矿成矿环境的刚察大寺、拉仁哇耳玛-拉仁修玛等地区的金矿找矿工作引起重视.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.
