广东嵩溪银—锑矿床属中低温浅成热液矿床。地质地球化学特征表明:银—锑矿床赋存于下侏罗统金鸡群上皮下部(J(ljc-1))以炭质页岩为主的碎屑岩建造中;空间上呈上锑下银;燕山晚期火山沉积为银、锑矿化提供了物质来源,后期热液使银、锑活化,进一步富集。
The Songxi silver-antimony deposit in Guangdong is a medium- and low-temperature epithermal deposit. Geological and geochemical characteristics show that the silver-antimony deposits occur in the lower epidermis of the Lower Jurassic Golden Chicken (J (ljc-1)), which is mainly composed of carbonaceous shale. The upper antimony silver deposit . Late Yanshan volcanic sediments provided the material source for silver and antimony mineralization. Later hydrothermal fluids activated and further enriched silver and antimony.
