Malachite

Cu₂(CO₃)(OH)₂

These samples of malachite are displayed in the Smithsonian Museum of Natural History. Malachite is a carbonate mineral of copper with the composition Cu₂(CO₃)(OH)₂. The sample at left is about 20 cm across and is from the Copper Queen mine, Bisbee, Arizona.

这些孔雀石标本陈列在史密森尼自然历史博物馆中。孔雀石是一种含铜的碳酸盐矿物，化学式为Cu₂(CO₃)(OH)₂。左侧的标本宽约20厘米，来自亚利桑那州比斯比市的铜皇后矿。

These two malachite sections are about 12 x 35 cm and are from the Copper Queen mine, Bisbee, Arizona.

这两个绿石块大约是12厘米×35厘米，来自亚利桑那州比斯比的铜王矿。

This sample shows blue azurite forming with green malachite. It is from Bisbee. It is about 9 cm high.

这个样本显示蓝色的蓝铜矿与绿色的孔雀石共同形成。它来自比斯比，高约9厘米。

This large multicolumn structure of malachite is about 35 x 50 cm and is from the Copper Queen mine, Bisbee, Arizona.

这种大型多列结构的孔雀石尺寸约为35厘米×50厘米，来自亚利桑那州比斯比的铜皇后矿。

This is a sample where malachite has overcoated a sample of cuprite, showing the geometry of the large cuprite crystals. The sample is about 20 cm across and is from Onganja mine, Seeis, Namibia. At right is an example of the cuprite crystals from the same location.

这是一个样本，其中malachite覆盖在cuprite样本上，展示了大型cuprite晶体的几何形状。该样本宽约20厘米，来自Namibia的Seeis Onganja矿。右侧是同一地点的cuprite晶体示例。

This large sample has vertical dimension probably 35 cm. It has azurite crystals on a base of malachite. It is from the Copper Queen mine, Bisbee, Arizona.

这个大样本的垂直尺寸可能为35厘米。其基质为绿铜矿，含有蓝铜矿晶体。该样本来自亚利桑那州比斯比的铜皇后矿。

This image is part of a section of a wall of a cave near Bisbee, Arizona. It is on display at Smithsonian Museum of Natural History. It shows the blue of azurite and the green of malachite.

这张图片展示的是亚利桑那州比斯比附近洞穴墙壁的一部分。该图片陈列在自然历史博物馆中。它展示了蓝绿色的蓝宝石和绿色的绿松石。

The azurite is characteristically blue. The green color is characteristic of malachite. This is another sample from the Copper Queen mine in Bisbee, Arizona. It is about 13 cm across.

蓝宝石具有典型的蓝色特征。绿色是孔雀石的典型特征。这是来自亚利桑那州比斯比的铜皇后矿的一块样本，直径约为13厘米。

This is another large multicolumn structure of malachite from the Copper Queen mine, Bisbee, Arizona. It is about 25 x 35 cm. The section shows the nature of the column growth with a small opening down the center. Note the small embedded azurite crystals.

这是来自亚利桑那州比斯比市铜王矿的另一种大型多列结构的孔雀石，尺寸约为25 x 35厘米。该截面展示了列状生长的特征，中间有一个小孔。请注意其中嵌入的细小蓝铜矿晶体。

This is malachite that has replaced azurite. It is not uncommon for one mineral to replace another and in the process take on the geometry of the other crystal. The form of azurite is clearly seen here but with the green color characteristic of malachite. This sample is from Tsuneb, Namibia and is about 20 cm across.

这是一种取代了蓝铜矿的孔雀石。一种矿物取代另一种矿物是常见的现象，在此过程中会呈现出另一种矿物的晶体形态。这里可以清楚地看到蓝铜矿的形态，但其绿色特征明显是孔雀石的。此样品来自纳米比亚的滕内布，直径约20厘米。

This sample is malachite formed after azurite with some quartz content. It is also from Tsuneb, Namibia and is about 10 cm across.

这种样本是形成于蓝铜矿之后的孔雀石，含有少量石英。它来自纳米比亚的茨内布，直径约10厘米。

This column structure of malachite appears to be a bit over 50cm high.

这种孔雀石的柱状结构似乎高达约50厘米。

The banded malachite sample above is about 20 cm wide and is from D. R. Congo.

上方带条纹的孔雀石样品宽约20厘米，来自刚果民主共和国。

Microscopic analyses of these banded malachite specimens show that they grew as layers of tiny crystals. When magnified about 70 times, it was found that the smaller crystals form light-green bands with larger crystals for the dark bands.

这些带状软玉矿石的微观分析显示，它们是分层生长的微小晶体。放大约70倍时，发现较小的晶体形成浅绿色带，而较大的晶体则形成深色带。

This sample of malachite is about 18 cm long and is from the Luiswishi mine, Elizabethville, D.R. Congo.

这种绿铜矿样本长约18厘米，来自刚果民主共和国的利斯维希矿。

This sample of malachite is about 20 cm wide. It is from Zambia.

这种绿铜矿样本宽约20厘米。它来自赞比亚。
