一透视石透视石(CuSiO_3·H_2O)又称绿铜矿、翠铜矿,呈绿色,莫氏硬度5,是宝石矿物和观赏矿物标本之一,国内产地目前很少报道。1971年我们在滇东北金沙铅锌矿床炎山矿段的氧化带中曾发现有极少量透视石产出。简要报道如下:该铅锌矿呈层状、透镜状及脈状,赋存于上震旦统灯影组含燧石条带白云岩的上部及下寒武系筑竹寺阶底部的白云岩、硅质白云岩、白云质板岩及磷质岩地层中。由于地形的强烈切割,背斜穹窿构造和地层出露清楚。矿床的矿物成分复杂,硫化物有:方铅矿、闪锌矿、黝铜矿、砷黝铜矿、车轮矿、黄铁
A perspective stone (Shiqiao) (CuSiO_3 · H_2O), also known as chalcopyrite, Cu Cu, green, Mohs hardness of 5, is one of the gem mineral and ornamental mineral specimens, the domestic production is rarely reported at present. In 1971, we found a very small amount of see-through stone in the oxidation zone of the Yan Shan section of the Jinsha lead-zinc deposit in northeastern Yunnan. A brief report is as follows: The lead-zinc deposits are stratiform, lenticular and vein-shaped, occurring in the Upper Sinian Dengying Formation containing chert-bearing dolomite and dolomite at the bottom of the Cambrian Lower Cambrian dolomite, silicon Dolomite, dolomitic slate and phosphate rock strata. Due to the intense cutting of the terrain, the anticline domes and strata are clearly exposed. The mineral composition of the deposit is complex. Sulphides are: galena, sphalerite, tetrahedrite, arsenic tetrahedrite, wheel ore, yellow iron
