摘要
本文在以往工作和研究的基础上,对该区内矿床成矿地质特征、控矿地质条件及找矿标志进行了分析,认为小岭乡矿床受区内构造、板块活动及元古代地层控制。区内北西向断裂及其派生的次级北西向断裂为矿区控矿、含矿构造;区内加里东期的地质矿物中富含氟元素,为甘肃永靖小岭乡矿床的形成提供了物质和动力来源,元古代皋兰岩群中-深变质地层含有较高成矿元素。
On the basis of previous work and research,this paper analyzes the ore-forming geological characteristics,orecontrolling geological conditions and prospecting criteria of the deposit in the area.It is believed that the xiaolingxiang deposit is controlled by the regional structure,plate activity and Proterozoic strata.The NW trending faults and their secondary NW trending faults are ore controlling and ore-bearing structures in the area;the Caledonian geological minerals in the area are rich in fluorine elements,which provide material and dynamic sources for the formation of xiaolingxiang deposit in Yongjing,Gansu Province,and the middle and deep metamorphic texture layers of the Proterozoic Gaolan group contain higher oreforming elements.
