沉积岩铜矿主要是沉积期后成因矿床,其成矿元素及成矿流体均来自沉积盆地。较上、下岩层具有高孔隙度和渗透率的粗碎屑岩是流体运移的通道与储矿岩层。在储矿岩层之上是由泥灰岩、泥岩、粉砂岩、碳质泥岩及蒸发岩组成的约3km厚的红色细碎屑岩系作为隔水层。含铜碎屑岩中具有一系列热液蚀变现象,红色碎屑岩与灰白色岩在横向与纵向上交错出现,铜矿物主要与含铁碳酸盐胶结物或碳酸岩脉伴生。含铜流体沿着高渗透率的粗碎屑岩层运移到古陆边缘、古隆起带、喀斯特溶洞或后期褶皱断裂带沉淀成矿。
Sedimentary rock copper deposits are mainly post-depositional genetic deposits, and their metallogenic elements and ore-forming fluids come from sedimentary basins. The coarse clastic rocks, which have higher porosity and permeability than the upper and lower strata, are the channels for migration of fluids and the strata of reservoir rocks. Above the reservoir rock is a 3cm-thick red finely divided clastic rock system consisting of marl, mudstone, siltstone, carbonaceous mudstone and evaporite. There are a series of hydrothermal alteration in the copper-bearing clastic rocks. The red clastic rock and the feldspathic rock alternate in horizontal and vertical directions. The copper minerals are mainly associated with iron-bearing carbonate cements or carbonate veins. Copper-bearing fluids migrate to the margins of ancient land along the high-permeability coarse-grained lithostratigraphy, with paleo-uplift, karst caves or later fold-folding faults.
