摘　　要：新疆东天山沙泉子地区位于雅满苏—沙泉子成矿区的东段 ,地层简单 ,但岩性复杂。受沙泉子深大断裂及沙泉子火山机构共同作用 ,地球化学异常表现为以 Cu- Zn- Ag- Mo为主的内环、以 Pb- Zn(Cu- As- Sb)为主的中环和以 Au或 Au- Ag- As- Sb异常区为主的外环 ,从中心至外围 Cu、Zn等异常强度、规模逐渐减弱 ,Au、As、Sb异常逐渐增强 ,在元素的空间分布上表现出Cu、Zn、Pb、Ag— Pb、Zn、As、Sb(Ag)— Au、As、Sb的元素分带现象。提出沙泉子北、苦水北二处找矿预测远景区 。Shaquamzi' area, eastern Tianshan, Xinjiang is located in the eastern part of Yamansu Shaquamzi metallogenic zone In the area, the stratum is simple , but the lithology is complex Because of multi geologic processes,for example, Shaquamzi deep rooted rift and Shaquamzi volcanic apparatus etc,the geo chemical anomalies is annular: the inner annulus is Cu Zn Ag Mo, the middle is Pb Zn(Cu As Sb),the outside is Au Ag As Sb from inner to outside , the Cu, Zn anomaly intensity is weaker and weaker , the Au, As, Sb anomaly intensity is stronger and strong In fact, there is anomaly trend Cu?Zn?Pb?Ag-Pb?Zn?As?Sb(Ag)-Au?As?Sb There are two ore finding forecast areas, and the prospect is very good
