| 摘 要： | 在1∶5万水系沉积物测量的基础上,对内蒙古额济纳旗珠斯愣地区的地球化学特征及其主控因素进行初步分析,并对元素分布特征、元素相关性分析、单元素异常与构造之间关系、综合异常与构造之间关系进行了探讨。研究发现,Cu、Au、Sb为区内具一定潜力的找矿元素,与呼伦西白-珠斯楞海尔罕反"S"形构造带南端内、外旋面的转换的珠斯楞海尔罕一带形成一个与断裂构造吻合度较高的、半环性的成矿成晕中心。因而推断,区内具有形成与中酸性侵入岩有关的热液铜多金属矿的可能,其中珠斯楞海尔罕铜金矿和道布青乌苏南北金锑矿2个找矿靶区严格受呼伦西白-珠斯楞海尔罕反"S"形构造的控制。

| Abstract: | On the basis of 1:50000 stream sediment survey, the authors made a preliminary analysis of the geochemical characteristics and main control factors of Zhusileng area in Inner Mongolia. The relationship of element distribution, element correlation analysis and single element anomaly to structure and the relationship between the anomaly and structure were investigated. It is found that Cu, Au, and Sb are potential prospecting elements in this area, which form a half-ring ore-forming and halo-forming center in relatively high accord with the fault structure in the converting Zhusilenghaierhan zone of inner and outer spiral surface at the south end of reverse "S" structure of Hulunxibai-Zhusilenghaierhan. Therefore, it is concluded that there may be hydrothermal copper polymetallic ore deposit related to the formation of intermediate-acidic intrusive rocks, where the gold deposit in Zhusilenghaierhan and two gold-antimony prospecting targets respectively in southern and northern Daobuqingwusu are strictly controlled by reverse "S" structure of Hulunxibai-Zhusilenghaierhan. |
