云南大宝山矿区望香台矿段的发现、地质特征及意义
|
摘要
云南维西大宝山矿区位于青藏高原东南缘,西南"三江"有色金属成矿带中。望香台矿段处于大宝山矿区东南部,是一成矿、赋矿条件十分有利地区,但因研究程度低,在该地区一直未取得找矿成果。经过近年来工作在此发现了5条矿体,矿体具连续性好、埋深浅、矿石品位稳定及规模大等特点,文章对矿段地质特征进行了分析总结。望香台矿段的发现不仅使大宝山矿区的资源量增加,而且对扩大该区找矿远景具有意义。
The Weixi Dabaoshan mining area is located at the southeast edge of the qinghai-tibet plateau,in Southwest China of"sanjiang"nonferrous metals metallogenic belt.Wangxiangtai mine is in the southeast of the Dabaoshan mining area,metallogenic and ore-occurrence conditions are favorable,however,the research is extremely low,no prospect results have been achieved in the region.Five important orebodies were found here after years of work,ore body characteristic of good continuity,shallow buried depth,ore grade stability and large scale.In this paper,the geological characteristics of the ore section are analyzed.The discovery of Wangxiangtai mine not only increases the resources of the Dabaoshan mining area,but also it is of great geological significance to enlarge the ore prospecting prospect.
