| 摘 要： | 在东秦岭钼成矿带最近探明的石窑沟大型钼矿床,位于近东西向马超营断裂带与北东向焦园断裂带的交汇部位,获得钼金属储量10余万吨.平均品位0.064%.矿区位于狮子庙金矿田上,钼矿外围有多个金及多金属矿床及矿点.笔者根据石瑶沟钼矿的赋矿地质条件和化探异常特征,阐述了钼矿的成矿地质条件,钼矿与外围金(银)矿之间的成因联系,提出本区成矿母岩为隐伏的小斑岩体,矿化富集部位为小岩体内外接触带,金银矿质来源主要为坡前街组地层,其成矿与岩浆活动关系密切.同时指出钼矿与金(银)矿床应属于同一成矿系统.据化探成果和钻探资料推测,在隐伏小岩体的周边还存在有类似石瑶沟隐伏岩体的小隐伏岩体,为该区今后的工作提出了新的找矿思路.

| Abstract: | The Shiyaogou deposit,located in the intersection part of the nearly EW-strike Machaoying fault belt with NE-strike Jiaoyuan fault belt,is a large molybdenum deposit newly discovered in molybdenum metallogenic belt,east Qingling,Henan Province.Currently,the proved reserve of the deposit is more than one hundred thousand tons,and the average grade is 0.064%.This molybdenum deposit is located in the Shizimiao gold orefield,and there are several gold or polymetallic deposits or ore spots in the surrounding are... |
