摘要
The Liwu copper deposit is located in the Jianglang metamorphic core complex,western margin of the Yangtze platform.Through research of the ore-bearing rock series by petrology and geochemistry,their protoliths were reconstructed and the tectonic-sedimentary environment was analyzed.Furthermore,ore genesis and the relationship between ore-bearing rock series and mineralization were discussed.The results show that the protolith of the Liwu rock group is a set of argillaceous-arenaceous marine sedimentary rocks in the passive continental margin,containing a little volcanic rocks.Metallogenic materials mainly come from the ore-bearing rocks proper,and the mineralization is characterized by multiple phases and many genesis.It was formed during the Yanshan period (133-143 Ma) by middle to high hydrothermal fluid mineralization,.Furthermore,it is controlled by ductile shear zones and dome structure.The genesis is of a reformed marine sedimentary type.
