解釋
黑鉍金礦-
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
經電子探針分析，高莊金礦有多種鉍碲化物，有三粒礦物的成分與標準葉碲鉍礦完全一致。對一較大顆粒的葉碲鉍礦做了單晶x射線衍射分析。 au與bi在礦石和圍巖中的含量呈共消長關系， te與bi可能對au ag的遷移富集起了重要作用。 -
