安化滑板溪—柑子园锌锑成矿区地质特征

Geological Characteristics of Zinc and Antimony Metallogenic of a rea Huabanxi—Ganziyuan,Anhua County

该成矿区位于雪峰孤形构造带东北段,赋存在两条北东向断裂夹持并具矿源层特征的下奥陶统宁国组砂页岩中。矿脉呈中一陡倾斜柱板状产出,严格受断裂构造控制。成矿作用与构造活动同步,属动力变质热液矿床类型。

Located on the NE part of Xuefeng arc-shaped structure zone, the mineralization occurs in the sandy shale of Ningguo formation of Ordovician System Which exbits some properties of mineralization source and lies between two faults with NE trend. Orebearing veins are in the forms of inclined pillar or plate, medium to steep dipping and are controlled by fractures and faults. Metallization, which took place synchronously with the tectonic activity, belongs to the hydrothermal deposit of dynamic metamorphism.
