摘要
文章介绍了滇西北地区斑(玢)岩分布情况、主要斑(玢)岩体的岩石化学特征,并利用常量元素标志对岩体的铜金含矿性进行评价,认为滇西北地区的斑(玢)岩体可分为五个岩带,金矿成矿有利岩体和铜矿成矿有利岩体两大类型,指出滇西地区具有广阔的斑岩找矿前景。
This paper describes the distribution of porphyry （porphyrite） in northwest Yunnan and lithochemi- cal characteristics of primary ore bodies of porphyry （porphyrite）. An evaluation on Cu-Ag ore-bearing po- tential of the ore bodies by macroelement markers was carried out. Porphyry （porphyrite） rock mass in northwest Yunnan are divided into five rock zones, or two types which are favorable rock mass for gold min- eralization and favorable rock mass for copper mineralization. It is concluded that west Yunnan area has a great prospecting potential of porphyry.
