摘要
通过对穷棒子沟钼矿床的研究,查明了矿体主要赋存于流纹斑岩体与安山岩的内外接触带400-600m范围内,钼矿体主要受围绕次生石英岩化流纹斑岩(硅化核)的环状构带所控制,构造岩石裂隙是钼矿(化)的主要运移通道和富集空间,其独特的环状空间形态,丰富了次火山岩热液型钼矿床的地质特征,具有重要的矿床学研究价值。
The study shows that Qiongbangzigou molybdenum deposit exists external -internal contact zone of rhyolite porphyry and andesite, within the range from 400 meter to 600 meter. The occurrence of molybdenum - ore -bodies are controlled by the circular structural belt, which circling the secondary quartzite rhyolite porphyry body（ core of silicate body）. The faults and fissures occurred in the belt provided passages and storage space for the molybdenum mineralization. The special circular tridimensional shape enriched the characterisitics of porphyritic deposit model, being of important study significance to gitology.
