Tetrahedrite

四面体石

These samples of tetrahedrite are displayed in the Smithsonian Museum of Natural History. Tetrahedrite is an sulfide mineral of antimony, copper and iron with the composition (Cu,Fe)₁₂Sb₄S₁₃ . This sample is about 14x14 cm and is from Mercedes mine, Huanuco, Peru. Tetrahedrite is mined as an ore of copper. These crystals of tetrahedrite were found lining and underground cavity in the Andes Mountains.

这些四面体矿石陈列在史密森尼自然历史博物馆中。四面体矿是一种含锑、铜和铁的硫化物，化学式为(Cu,Fe)₁₂Sb₄S₁₃。这块样品大小约为14×14厘米，来自秘鲁胡安科的梅赛德斯矿。四面体矿作为铜的矿石被开采。这些四面体矿晶体发现于安第斯山脉的洞穴内壁。

This sample is described as tetrahedrite with chalcopyrite. It is about 15x8 cm and is from Herodsfoot mine, Liskeard, Cornwall, England. You can see two copper ores in this specimen - dark gray crystals of tetrahedrite, topped by brassy crystals of chalcopyrite.

这种样本被描述为四面体矿和黄铜矿。它大约15x8厘米，来自英格兰康沃尔郡利斯凯德的赫罗德斯脚矿。你可以看到这种标本中有两种铜矿——暗灰色的四面体矿晶体，顶部覆盖着黄铜矿的金黄色晶体。

This sample is described as tetradedrite with quartz. This sample is about 5x6 cm and is from Park City, Utah.
