通过对夏河地区金矿的地球化学特征的研究 ,认为该地区存在着巨大的金矿找矿优势和银、锑矿潜力。提出该区找金以浅成低温热液型为主 ,以构造蚀变型、石英闪长岩型为远景矿化主要类型。指出下三叠统是有利的成矿部位 ,中酸性岩体、构造蚀变破碎带是富金的场所。明确了异常 +构造 +岩脉 +蚀变的综合找矿标志。确定了 3个异常带是寻找金矿的基本目标。
Through the study of the geochemical characteristics of the gold deposits in Xiahe area, it is considered that there is a great potential for gold prospecting and silver and antimony ore in the area. It is proposed that the area should be gold-to-light and low-temperature hydrothermal, dominated by alteration, and quartz diorite should be the main type of prospecting and mineralization. It is pointed out that the Lower Triassic is a favorable metallogenic site, and the acidic rocks and structural alteration and crushing zone are rich gold sites. Clear the abnormal + structure + veins + alteration of the comprehensive ore prospecting. Three anomalous zones were identified as the basic goal of finding gold mine.
