摘要

在捷克西波西米亚Michalovy Hory矿区Grubenwall 42矿(Kramolín)的排土场材料中发现了明显的带状四面体-tennantite晶体。四面体-tennantite形成一层四面体，部分腐蚀的晶体，大小可达1毫米，在晶体石英的外壳上，与黄铜矿和铜矿相结合。振荡带状晶体中的单个带由三种四面体族矿物组成:四面体-(Zn)、tennantite-(Zn)和稀有的tennantite-(Fe)。观察到的asb -1取代范围在单晶中是不寻常的，这表明热液流体中As/Sb比具有很高的变异性。

Výrazně zonální tetraedrit-tennantit z Kramolína, rudní revír Michalovy Hory (Česká republika)

The crystals of significantly zonal tetrahedrite-tennantite were found in the mine dump material of the Grubenwall 42 mine, Kramolín, the Michalovy Hory ore district, western Bohemia (Czech Republic). Tetrahedrite-tennantite forms layer of tetrahedral, partly corroded crystals up to 1 mm in size on a crust of crystalline quartz in association with chalcopyrite and cerussite. Individual zones in oscillatory zoned crystals are represented by three members of tetrahedrite group minerals - tetrahedrite-(Zn), tennantite-(Zn) and rare tennantite-(Fe). The observed range of AsSb-1 substitution is unusual within a single crystal and indicates high variability of the As/Sb ratio in the hydrothermal fluids.
