| 摘 要： | 通过对东昆仑祁漫塔格弧后裂陷构造带内的四角羊铅锌多金属矿床的成矿地质特征与地球化学特征研究,认为矿床受花岗岩侵入体与碳酸盐岩之间的接触带及碳酸盐岩内断裂裂隙构造控制,呈似层状、透镜状,微量元素和稀土元素特征显示其成因类型为矽卡岩型;四角羊地区铅锌多金属矿找矿工作应在碳酸盐岩分布区,有印支期碱性花岗岩侵入,物探测量有1∶5万磁异常显示区进行。

| Abstract: | Based on studying in mineralization geological features and geochemistry characteristic in Sijiaoyang Pb-Zn polymetallic deposit located at Qimantage back-arc rift structure zone belt,it is described that the ore is limited in the localization area of the outsides contact zone between magmatic rock and marble and another fissures,and it like layered or lens,a nd characteristics of Trace element and REE show that the causes of type is skarn polymetallic deposits.Sijiaoyang ore prospecting work should be carry out the areas,where occur the carbonate,Indosinian alkaline granite and 1∶5 million magnetic anomaly. |
