(Mg,Al)₆(Si,Al)₄O₁₀(OH)₈
This sample of clinochlore is displayed in the Smithsonian Museum of Natural History. Clinochlore is a mineral that contains four of the big 8 elements of the Earth's crust. The composition is (Mg,Al)6(Si,Al)4O10(OH)8. The sample at left is about 10 cm across and is from Kop chrome mine, Daglari, Anatolia, Turkey. This sample is described as chromian clinochlore, presumably because inclusions of chromium in the chromium mining area contribute the purple color. Other samples of clinochlore have colors from green to blue.
这种氯钠石样品陈列在史密森尼自然历史博物馆中。氯钠石是一种含有地球地壳中八大元素中四种的矿物。其化学式为(Mg,Al)6(Si,Al)4O10(OH)8。左上方的样品宽约10厘米,来自土耳其安纳托利亚达格拉里Kop铬矿。该样品被描述为含铬氯钠石,可能是因为铬矿区内含铬包裹体使样品呈现紫色。其他氯钠石样品的颜色从绿色到蓝色不等。
