内蒙古天太永斑岩型钼矿床分带特征研究
|
摘要
天太永斑岩钼矿位于内蒙古中部地槽褶皱系东段的温都尔庙-翁牛特旗加里东地槽褶皱带,矿体产于燕山晚期北东向展布的花岗斑岩岩体内,矿体围岩蚀变较强,本文通过野外实地调查,结合该区近年来地质勘查成果,综合分析认为天太永钼矿在地表金属元素异常、矿石构造及矿化蚀变组合类型等方面均具有明显的分带性,符合斑岩型钼矿床的蚀变分带特征,有进一步勘查及科研价值。
The Tian Tai permanent porphyry molybdenum deposit is located in the east part of the geosyncline fold system in the eastern part of Inner Mongolia. The orebody is produced in the granite porphyry in the late North East of Yanshan, and the rock alteration of the ore body is stronger. The combined analysis shows that the Tian Tai Yong molybdenum ore has obvious zonation in the surface metal element anomaly, ore structure and mineralized alteration combination type, which conforms to the alteration zoning characteristics of the porphyry molybdenum deposit, and has further exploration and scientific research value.
