FeCO₃

Siderite is a carbonate mineral of iron. It has the composition FeCO₃. The origin of this sample is Lukmanierschlucht, Grissons, Medel, Switzerland. It is on display in the Smithsonian Museum of Natural History. The sample measures about 12x12 cm.

siderite 是一种含铁的碳酸盐矿物。其化学式为 FeCO₃。该样品采自瑞士格里松斯、梅德尔的卢克曼伊施卢特。该样品陈列于史密森尼自然历史博物馆。样品尺寸约为 12 厘米×12 厘米。

Siderite is a member of the calcite group of carbonates along with rhodochrosite and Smithsonite. Siderite is a minor ore of iron. Its name derives from sideros, the Greek word for iron.

siderite 是与 rhodochrosite 和 smithsonite 同属碳酸盐类的矿物。它是一种铁的次要矿石。其名称来源于希腊语中的 'sideros'，意为铁。

Looking profoundly different from the sample above, this siderite is from Baia Sprie, Crisana-Maramures, Romania and measures about 12x14 cm. It has the appearance of a cluster of spherical shapes, each sphere containing thin petal-like structures.

与上述样本截然不同，这块 siderite 来自罗马尼亚 Crisana-Maramures 的 Baia Sprie，尺寸约为 12x14 厘米。它呈现出一簇球形结构的外观，每个球体内都包含细薄的花瓣状结构。

Another form of siderite shows thicker plate structures. This sample is from Wheal Maudlin, Cornwall, England and measures about 7x10 cm.

另一种 siderite 的形态呈现较厚的板状结构。该样本来自英格兰康沃尔郡的 Wheal Maudlin，尺寸约为7x10厘米。

The small sample above is yet another form of siderite, a solid cubical structure about 4x4 cm from Mont Saint-Hilaire, Quebec, Canada. The sample at right is siderite with quartz from Morro Vellio mine, Nova Lima, Minas Gerais, Brazil. That sample is about 8x11 cm.

上面的小样本是另一种 siderite，来自加拿大魁北克省蒙圣希拉尔，是一种约4x4厘米的立方体结构。右边的样本是来自巴西米纳斯吉拉斯州诺瓦拉维埃洛矿的 siderite 和石英，尺寸约为8x11厘米。

Another example of siderite with quartz comes from Allevard, Isere, France, measuring about 8x8 cm.

另一块 siderite 与石英共生的岩石来自法国伊泽尔省的Allevard，尺寸约为8x8厘米。

A sample from Llallagua, Potosi, Bolivia is siderite with pyrite, measuring about 12x15 cm.

玻利维亚波托西的利兰加矿石样本中含有磁铁矿和黄铁矿，尺寸约为12x15厘米。

Galena with siderite. Sample measures about 12x12 cm and is from Neudorf, Germany.

Galena与 siderite 的混合物。样品尺寸约为12x12厘米，来自德国Neudorf。

Ferberite with arsenopyrite and siderite. The black, shiny crystals are ferberite, an ore of tungsten. The silvery crystals are arsenopyrite, an ore of arsenic. The siderite crystals form the frosting. The sample size is about 14x14 cm and it is from Panasqueira, Portugal.

样品尺寸约为14x14厘米，采自葡萄牙潘纳斯奎拉。其中黑色、有光泽的晶体是ferberite，是一种钨矿石。银色的晶体是arsenopyrite，是一种砷矿石。 siderite晶体形成表面的霜状结构。
