Helvite (or Helvine)

Helvite (或 Helvine)

Mn4Be3(S(SiO4)3)

Mn₄Be₃(S(SiO₄)₃)

This sample containing helvite is displayed in the Smithsonian Museum of Natural History. The sample is described as spessartine with helvite, quartz, and microcline. Helvite is a silicate mineral of beryllium, sulfur and manganese with the composition Mn4Be3(S(SiO4)3). The sample at left is about 20 cm long and is from Tongbei, Fujian Province, China. The black crystals are taken to be microcline, the orange spessartine, and the tan helvite. The typical color for helvite is golden yellow to brown.

这个含有 helvite 的样本陈列在史密森尼自然历史博物馆。该样本被描述为含有 spessartine、helvite、石英和 microcline。Helvite 是一种成分包含铍、硫和锰的硅酸盐矿物,其化学式为 Mn₄Be₃(S(SiO₄)₃)。左下方的样本长约20厘米,来自中国福建省 Tongbei 地区。黑色的晶体被认为是 microcline,橙色的是 spessartine,而棕色的是 helvite。helvite 典型的颜色为金黄色至棕色。

This sample is described as helvite with quartz and pyrite. You can see three generations of growth in this speciment. Clear quartz formed first. The yellow crystal of helvite grew on top, and flecks of brassy pyrite crystallized later. The sample is about 5x5 cm and is from Pachapaqui mine, Huanuco, Peru.

这个样本被描述为含有石英和黄铁矿的 helvite。你可以看到这个样本中有三个世代的生长。透明的石英最先形成。黄铁矿的黄色晶体随后生长在上面,而后来又出现了黄铜色的黄铁矿结晶。这个样本大约5x5厘米,来自秘鲁胡安库乔矿。
