Abstract: Pilsenite is a rare mineral and its information is deficient. The first found pilsenite in China is in Gaozhuang, Henan province. Pilsenite, associated with pyrrhotite, pyrite, hessite, gold, produced in pyrrhotite-polymetallic stage. Three bismuth-tellurides produced in Gaozhuang are well concordant with the standard pilsenite in composition, and other three are different from any of known bismuth-tellurium minerals. Single crystal diffraction were made on a larger mineral grain of pilsenite. Au growth and decline together with Bi and Te in ores and wall-rocks, which suggests that Bi and Te play a important role in migration and enrichment of Au.

Key words: Gaozhuang gold deposit, pilsenite, single crystal diffraction

摘要： 叶碲铋矿极为罕见，矿物学资料匮乏。高庄金矿的叶碲铋矿为中国首次发现，它主要产于磁黄铁矿-多金属阶段，与磁黄铁矿、黄铁矿、黄铜矿、碲银矿、自然金等共生。经电子探针分析，高庄金矿有多种铋碲化物，有三粒矿物的成分与标准叶碲铋矿完全一致。对一较大颗粒的叶碲铋矿做了单晶X射线衍射分析。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、Ag的迁移富集起了重要作用。
