| 中文摘要: |
| 山西省茶坊金矿床产于新太古代奥长花岗岩(黑云斜长片麻岩)缓倾斜构造破碎带中。该矿区内断裂发育,其周边有燕山晚期石英斑岩、花岗闪长斑岩和辉石闪长岩呈脉状和小岩株状侵入。通过对茶坊金矿的矿床地质特征和矿床地球化学特征进行综合研究,认为茶坊金矿属于与燕山晚期次火山岩浆活动有关的中低温热液型金矿。 |
| 英文摘要: |
| Chafang gold deposit in Shanxi Province occurs in a gently inclined tectonic fracture zone of Neoarchean trondjemite (biotite plagioclase gneiss) with faults, dykes and small stocks of Late Yanshanian quartz porphyry, granodiorite porphyry and pyroxene diorite developed. This paper deals with geological and geochemical characteristics of the gold deposit and genesis on basis of geollogical and geochemical data available now. It is considered that the deposit is a meso-epithermal gold deposit related to Late Yanshan subvolcanic magmatic activity. |
