小秦岭地区的钼矿床产于华北地台与秦岭地槽的接合部位。该区晚元古代至古生代形成的近东西向复杂构造带的活动性,表现出南北方向上有较大的差异,中生代开始地壳活动进入新的阶段,地台和地槽都进入活动状态,构造作用和岩浆活动极其强烈,形成一系列叠加在东西向基底构造上的北东向隆起凹陷带和断裂组。在北东向与东西向构造的复合部位造成大量中酸性岩侵入,并形成了许多可供工业利用的钼矿床。因此,近几年来地质部门和冶金地质勘探公司都将该区作为重点找钼之地。笔者随同我所钼矿组在此区做了一些工作,并根据陕西地矿局、冶金地质系统及其它单位实际资料的综合研究,试图对小秦岭地区钼矿床的地质特征及成矿进行初探。对提供资料
The molybdenum deposit in the area of small Qinling Mountain is produced at the junction of North China Platform and Qinling Gully. The activities of the NE-Westerly complex tectonic belt formed from Late Paleozoic to Paleozoic showed a large difference in north-south direction. The crustal activity in Mesozoic began to enter a new phase, and both the platform and the trough were in active state. The action and magmatic activity are extremely intense, forming a series of NE-trending uplift and depression groups superimposed on the east-west basement structure. A large amount of intermediate-acidic rocks intruded into the composite parts of NE-trending and east-west structures and formed many molybdenum deposits for industrial utilization. Therefore, in recent years, geology departments and metallurgical geological exploration companies regard the area as a key area to find molybdenum. I have done some work in this area along with our molybdenum group, and based on the comprehensive study of actual data of Shaanxi Bureau of Geology and Mineral Resources, metallurgical geological system and other units, I try to explore the geological characteristics and mineralization of the molybdenum deposit in Xiaoqinling area.
