摘要
本文将康滇地轴中南段元古代地层中的铀矿化划分为３种类型（砂岩型、钠交代岩型和浅变质岩型），其中以钠交代岩型为主，并具有一定的找矿前景。而众所关注的中、上元古界不整合面型铀矿化至今未找到，初步认为其生成条件较差，找矿前景不乐观。
This paper has divided uranium mineralization in Proterozoic of the central-south sectionof Kham-Dian axis into three types (sandstone type,sodium metasomatite type and Proterozoic epimetamorphic rock type),of which the sodium metasomatite type is predominant andhas certain prospecting potential. But up to now,no unconformity-related uranium mineralizations in Middle and Late Proterozoic have been descovered,which are of great public concern,It is preliminarily considered that its formation conditions are poor and the metallogenetic prospect is not allowed to be optimistic.
