层状铜矿床或砂岩铜矿床,从前寒武纪至新第三纪各时代均有广泛分布。矿床规模很大,有时可达巨型,矿体具简单层状,延伸很大,有用成分含量相当高且分布均匀等等,使得可将这种铜硫化物矿化类型列为主要工业类型。关于层状铜矿床的成因已争论了多年,既有原生一沉积论者,也有后成论者。砂岩铜矿床硫同位素组成的研究表明,矿石中硫化物硫的来源归因于硫酸盐的还原过程。对个别矿区 Layered copper deposits or sandstone copper deposits, from the Precambrian to the New Tertiary era are widely distributed. The deposit is large in scale, sometimes up to a giant size, with a simple layered ore body, large extensions, a very high content of useful components and even distribution, making this copper sulphide mineralization a major industrial type. The cause of stratigraphic copper deposits has been debated for many years, both as a sedimentist and as a conclusive one. Studies of the sulfur isotopic composition of the sandstone copper deposit show that the source of sulphide sulfur in the ore is attributed to the reduction of sulphate. For individual mining area
