摘要
Abstract
Yangshan gold deposit in Gansu Province is the largest one discovered in China so far. 6 ore blocks are located in Devonian System. Metal minerals are mainly pyrite and arsenopyrite. Pyrite is mainly in three occurrences i. . e. disseminated micro-grained pyrite, sub-euhedral pyrite assemblage and big euhedral single pyrite crystal. Such pyrites are mainly distributed in phyllite, granitic diorite and quartz veins occurring in multi-stages and types. Au mineralization is related to the first stage disseminated medium-fine grained pyrite in quartz vein. Pyrite is one of the important gold carriers. Native gold occurs as micro-grain in cracks of pyrite and interstitial of pyrite crystals. Occurrence and distribution study of pyrite is of significance to further prospecting in the mining district. 关键词
