摘　　要：本文对黔西南和桂北地区微细浸染型金矿床矿物组合中的汞砷锑硫化物标型特征研究表明，辉锑矿的标型特征区别于单一锑矿床中的辉锑矿；雄黄在成分、晶胞参数和红外光谱等方面的标型特征与同类型四川东北寨金矿床中的维黄相似；辰砂的形态和成分特征可作为判断矿体侵蚀截面深度的标志和指示矿体延深程度的依据。In this paper the typomorphic features of Hg, As,Sb sulfides occuring in the micro-disseminated gold deposits from the provinces of southwestern Guizhou and northern Guangxi have been studied.The results obviously indicate that the typomorphic characteristics of stibnite from these mines are much diffrent from those samples coming from antimony ore deposit of China. The chemical composition , unit-cell parameter and infrared absorption spectrum of realgar coming from these Au-deposits in comparison with that of Dongbeizai Au-deposit,Sichuan province show some similar characteristics. And the crystal habit as well as chemical composition of cinnabar occuring in the micro-disseminated gold deposits show that typomorphic variations also might be used as an indicator of ore-body for the erosion depth and extension estimations.
