LiAlSi₂O₉

Spodumene is a silicate which contains lithium with composition LiAlSi₂O₉. This sample is about 35x45 cm and described as spodumene-bearing pegmatite. It is from Long Creek Church, Kings Mountain, North Carolina. These samples are on display at the Smithsonian Museum of Natural History.

斯波离石是一种含锂的硅酸盐，其化学式为LiAlSi₂O₉。这种样品尺寸约为35x45厘米，被描述为含斯波离石的伟晶岩。它来自北卡罗来纳州金斯山的朗斯克里克教堂。这些样品陈列在史密森尼自然历史博物馆中。

Spodumene is often found in pegmatites, and in fact accounts for one of the largest crystals on record. At the Etta Mine in South Dakota, a spodumene crystal was found which was 42 feet long, 5 feet in diameter and weighed 90 tons!

斯波丁矿常出现在伟晶岩中，事实上，它曾创下最大的晶体记录之一。在南达科他州的埃塔矿，发现了一块长达42英尺、直径5英尺、重90吨的斯波丁矿晶体！

The spodumene gems at left are 0.7,0.4,0.2 and 0.7 carats and are from Stony Point, North Carolina. The mineral samples are from Hiddenite mine, Alexander County, North Carolina. All these samples are of the hiddenite variety. The longest sample is about 5cm.

In order to maintain a relative scale, all the above spodumene gem images were patched from the same photograph. The two on the left are 163/9 and 77 carats and are from Nuristan, Afghanistan. The third is 287.8 carats and is from Minas Gerais, Brazil. The fourth and fifth are 60.7 and 170.6 carats and are from Pala, California.

All of these large spodumene gems are from Minas Gerais, Brazil. They are of size 62.6, 75.2, 327.8 and 255.8 carats. The largest one is maybe 10 cm across!

This large sample of spodumene is probably 18x35 cm and is from Afghanistan. It is formed with beryl and cookeite.
这种较大的spodumene样本可能尺寸为18x35厘米，来自阿富汗。它与碧玺和cookeite一起形成。

This sample of spodumene is of the variety kunzite from Nuristan, Afghanistan. It is probably 25cm high.

这种spodumene样本是来自阿富汗努里斯坦的kunzite品种，高度约为25厘米。

The sample of spodumene at left is about 12x25 cm and is from Brazil.

左边的spodumene样品尺寸约为12x25厘米，来自巴西。

This spodumene gem is 880 carats and is from Brazil.

An example of spodumene's use in jewelry.

spodumene 在珠宝中的一个应用示例。

These spodumene crystals are from the Vandenberg mine in La Pala, California and Resplender mine, Minas Gerais, Brazil. The tallest one is about 20 cm tall.

这些spodumene晶体来自加利福尼亚州La Pala的Vandenberg矿和巴西Minas Gerais的Resplender矿。最高的那块大约20厘米高。

"Spodumene is found almost exclusively in pegmatites, where it can form enormous crystals - up to 14.6 m (48 ft) long! Manganese colors the pink gem variety, kunzite."

斯波丁矿几乎只存在于伟晶岩中，在那里它可以形成巨大的晶体——长达14.6米（48英尺）！锰元素使粉色的宝石品种 Kunzite 呈现颜色。
