Daughter minerals in fluid inclusions of garnet and diopside from Tongguanshan Copper Deposit by SEM/EDS and LRM

Tongguanshan copper deposit of Tongling large ore belt is one of the typicalskarn copper deposits. Based on careful observation under microscope many daughter mineralsincluding transparent ones and opaque ones have been distinguished in the fluid inclusions of garnetand diopside. The results of SEM/EDS (scanning electron microscope/energy dispersive spectrometer)and LRM (laser Raman microprobe) analysis show that these daughter minerals in garnet are sylvite,halite, sphalerite, chalcopyrite and carbonate. Sylvite daughter mineral is very popular in garnetand diopside. The existence of so much sylvite daughter mineral and other daughter minerals in thefluid inclusions indicates that the ore--forming fluid is of supper-high salinity and high potassiumconcentration. High potassium concentration in the fluid inclusions agrees with K-richmesotype--acid rock and K-silicate alteration that occurred widely in this area. The daughtermineral assemblage in garnet and diopside is similar to the mineral assemblage of ore-forming stagethat followed skarn stage.

浅析罗家村矽卡岩铜矿床矿体地质研究

铜陵地处长江中下游铜铁金成矿带,成矿条件有利,矿产资源丰富,铜官山矿田就位于安徽省铜陵市东南郊,罗家村矿床位于铜官山背斜北西翼。矿体顶板地层主要为二叠系孤峰组和栖霞组,多为大理岩、含硅质碳质角岩,底板主要为石英闪长岩及矽卡岩等。
