摘要
在广西凭祥市早三叠世火山岩中首次发现的数个具工业价值的微细粒型金矿，肯定了它是我区新的找金层位，拓宽了找金的新领域。根据地质勘查资料，通过对龙塘、山更土两个主要矿床的剖析，论述该类金矿成矿的区域地质背景、矿床地质特征、找矿标志及找矿前景。
Several micro-fine grain gold ore deposit with industrial value was first found within volcanic rocks of lower Triassic in Pinxiang of Guangxi, which makes sure that is new prospecting gold- bearing formation, and opens up new prospecting gold ore field. The regional geological background, geological feature of deposit, prospecting criteria and prospecting future of this type deposit will be discussed in this paper after we have discussed two main deposits that are Longtang and Gengtu according to geological exploration data.
