摘要
从岩石化学方面分析得出晚三叠世火山岩属于钙碱性系列，其形成环境为活动大陆边缘，有利于斑岩型铜矿的形成。在此基础上描述了下西台南沟铜矿点、哈次谱山铜矿点和景忍山北坡铜矿点的矿化特征，提出了柴达木东南缘都兰－香日德地区和景忍山地区具有寻找隐伏斑岩型铜矿的可能性。
The volcanic rocks belong to calci - alkaline in lithology, and ware formed in the continental margin, which is conductive to mineralization of copper. Based on these researshes, the Xiashitainangou, Hacipushan and Jingrunshanbeipo copper occurrences are detailed. It is suggested that the Dulan - Xaingride area and Jingrunshan area in the southern margin of Chaidamu have prospecting potential of copper resources.
