摘要
在陕西黄龙金矿发现了多粒碲铋矿物,根据电子探针分析数据,其中有几粒的成分与因硫碲铋矿相近,颗粒大小为十几到几十微米,与黄铁矿、闪锌矿、赤铁矿等共生。Au与Bi在矿石和围岩中的含量呈共消长关系,Te与Bi可能对Au的迁移富集起了重要作用。
Ingodite is a rare mineral about which there has been little information. Ingodite found for the first time in China occurs in the Huanglong gold deposit Shanxi Province. Ingodite is associated with pyrite, sphalerite and hematite. Electron microprobe analysis has proved that one is tetradymite and the other is produced in Huanglong, both being well consistent with the standard ingodite in composition. Gold increases or declines with Bi and Te in ores and wall rocks, which suggests that Bi and Te play an important role in the migration and enrichment of Au.
