四川某含硒、银砂砾岩铜矿位于康滇地轴东侧会理断陷红色盆地的西南面。矿区北部是澄江期摩挲营花岗岩及一些海西期基性、超基性岩,矿区北西是晚二叠纪龙帚山玄武岩,西侧是含铜较高的会理群地层。与上述岩体有关的铜矿点、铜镍矿点较多,它们为本矿区提供了丰富的矿质来源。该矿由三个矿段组成。铜矿体产于白垩纪上统小坝组大铜厂段底部砂砾岩中。主要有六个矿层,组成
A selenium and silty conglomerate copper deposit in Sichuan is located in the southwest of the red basin of the Huilidi earth axis eastward fault. The northern part of the mining area is the Chengjian Mabianying granite and some Hercynian basic and ultrabasic rocks. The ore-bearing northwesterly is the Late Permian Longchaoshan basalts and the western side is the high copper-bearing Huili group strata. The copper deposits associated with the above-mentioned rock mass have a large number of copper and nickel deposits, which provide abundant mineral resources for this mining area. The mine consists of three sections. Copper ore body produced in the Cretaceous Xiaobang Formation copper block at the bottom of the conglomerate. There are six main ore layers
