雅满苏-山口地区1∶5万岩屑地化异常特征及找矿潜力

Rock Fragment Geochemical Anomalies and Prospecting Potential of Yamanshu-shankou Area

通过分析成矿地质背景和成矿地质条件,雅满苏-山口地区从北往南划分为东北滩-山口站晚古生代隆起、苦水构造混杂岩带、雅满苏-雅东晚古生代隆起四个构造单元,Cr Ni Co、Ag Pb Sb Zn Mo Au As、WSn Mo Bi(Sb)、Cu Mn(Mo Sn)四个成矿元素组合,主成矿元素为Au、Ag。研究区内圈定综合异常36处,其中A1类异常10个;A2类异常26个,划分出9个成矿远景区、10个找矿靶区,这些区域是今后找矿工作的重点区域,为下一步开展找矿工作部署提供了参考资料。

This paper investigated the mineralization backgrounds and mineralization conditions of Yamanshu-shankou area in Xinjiang and from north to south it is divided into four tectonic units: the Dongbeitan-Shankou late Paleozoic uplift,the Kusui tectonic melange belt,Yamanshu-yadong late Paleozoic uplift,with four ore-forming combination elements: Cr Ni Co,Ag Pb Sb Zn Mo Au As,WSn Mo Bi( Sb),the Cu Mn( Mo Sn). The main ore-forming elements are Au and Ag. 36 comprehensive anomaly were delineated( including 10 of A1 class anomaly,26 of A2 class anomaly.). 9 metallogenic prospect areas,and 10 prospecting target areas were pointed out,which indicated the next ore-founding direction in Tuoranggekuduke area.
