广东嵩溪银—锑矿床的地质地球化学特征

GEOLOGICAL AND GEOCHEMICAL CHARACTERISTICS OF SONGXI Ag-Sb DEPOSIT IN GUANGDONG

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。

Songxi Ag - Sb deposit belongs to an epithermal deposit. It occurs in the bottom of lower Jurassic Jingje Group upper part (Jljc- 1 ), which is a formation of detrital rocks mainly consisted of carbonaceous shale. Ag is found in the upper and Sb in the lower. The volcanic activity in late Yanshan provided the materials for Ag - Sb mineralization. Ag - Sb was mobilized by late hydrothermal fluid, resulting in enriched deposit.
