摘要
从金银矿物形态、金矿物成色、微量元素等方面对红石砬子金银矿床金银矿物标型进行了研究,对其成因标志意义进行了探讨.认为金矿物以银金矿为主,赋存状态为晶隙金、裂隙金和包体金.金矿物成色为334～813,平均为664.微量元素以含Bi、Cu、Sb相对高为特征,反映出该金银矿床成因类型是浅成中低温热液矿床.
The Hongshilazi gold-silver orefield in Liaoning Province is tectonically located on the east margin of the Yixian Mesozoic fault basin, Western Liaoning syneclise. The typomorphic characteristics of Au-Ag minerals in the deposit are studied on the morphology of Au-Ag mineral, fineness of Au minerals and microelements, which are significant for the genesis discussion of the deposit. The result shows that the Au mineral is dominated by electrum, occurring between crystals, in cracks and inclusions. The fineness of gold ranges from 334 to 813, in average of 664. The microelements of Bi, Cu and Sb are relatively high in the content. The typomorphic characteristics suggest the origin of epi-mesotheomorphic Au-Ag deposit.
