论地洼构造对砂岩铜矿床的控制作用
ON THE CONTROLLNG OF DIWA STRUCTURE TO SANDSTONE COPPER ORE DEPOSIT
【摘要】 本文以四川会理地洼盆地为例,论述了地洼构造对砂岩铜矿床成矿的控制作用。即地洼盆地沉积前基盘构造控制了盆地的形态及矿源层的展布方向和物质来源;沉积期构造任制了矿源层的岩相和厚度;沉积后的构造决定了储矿砂体的空间位置、铜质来源和矿体的形成;成矿后的构造对砂岩铜矿床成矿的控制有二重性:一方面可以形成新的矿体;另一方面可破坏原来已形成的矿体。
【Abstract】 This paper expounded the controlling of diwa structure to sandstone copper ore deposit.That is’ the structures before sedimenting control the shape of basin, the distributed directions of source beds and the material source;the material source;the structures after sedimenting control the space location of ore storage sandbody,thesupplying source of copper element and the forming of ore bodies;thestructures after ore deposit forming, either reformed new ore beds or destroied original industrial ore beds.
