德兴矿田朱砂红铜多金属矿床地质构造特征

Geological Structural Characteristics of the Cinnabar Red Copper Polymetallic Deposit in Dexing Ore Field

德兴铜矿田大地构造位置为扬子地块与华夏地块碰撞的华南造山带中,区内褶皱、断裂构造发育,矿产与岩浆岩及构造关系密切。朱砂红矿床位于矿田的西北部,通过详查地质工作资料,基本查明了矿区地质和矿床特征。从含矿斑岩、围岩蚀变、控矿构造、矿体特征及矿石质量等方面初步总结了朱砂红铜多金属矿床地质构造特征和矿床成因。认为该矿床具有典型的岩控矿床特征,进一步丰富了斑岩型铜矿床找矿模型。

The geotectonic location of the Dexing copper ore field is located in the South China oro⁃genic belt where the Yangtze block and the Cathaysia block collide.Folds and faults are developed in the area,and minerals are closely related to magmatic rocks and structures.From the aspects of ore-bearing porphyry,wall rock alteration,ore-controlling structure,ore body characteristics and ore quality,the geo⁃logical structure characteristics and the genesis of the cinnabar red copper polymetallic deposit are prelimi⁃narily summarized.It is believed that the deposit has typical characteristics of rock-controlled deposits,which further enriches the prospecting model of porphyry copper deposits.
