福建连城中坪矿区铁多金属矿地质特征及成因探讨

Geological Features and Genesis of Zhongping Iron Polymetallic Deposit in Liancheng County,Fujian Province

连城中坪矿区地表以风化淋滤型铁锰矿为主,受断裂及地层控制,深部隐伏多金属矿。通过对该矿床的矿体、矿石、蚀变等特征的研究,认为该矿床深部隐伏矿成矿作用主要受晚石炭世经畲组中的层间断裂控制,碳酸盐岩是成矿的有利围岩,矽卡岩矿物及其组构特征明显,矿床成因类型属矽卡岩型。

The surface of Zhongping deposit in Liancheng county is mainly Weathering leaching i- ron manganese ore , controlled by faults and strata, the deepth concealed polymetallic ore. Study on the ore body, ore characteristics and alteration characteristics of the deposit, it is consider that deep concealed mineralization of the deposits is mainly controlled by affected by the interlayer fault in the late carbon Jingse group. Carbonate rocks are favorable to the fa- vorable surrounding rocks, and Skarn mineral and its structure characteristics are obvious. The genetic type belongs to the skarn type deposit.
