| 摘 要： | "金钱石"作为观赏石中的珍品,倍受人们的青睐。岩石自然类型为超基性岩(超镁铁质岩),色暗,密度大,富含铁镁矿物。主要矿物成分为橄榄石、辉石,少量角闪石。岩石成因为幔源岩浆沿构造裂隙或古薄弱带扩张充填的产物。其精美的花纹图案与岩浆自身的结晶分异和后期变质作用等有关。

| Abstract: | As ornamental stones treasures, "Jinqian stone" has been enjoyed by many people. Its natural type is ultrabasic rocks (ultramafic rocks), dark color, density, and rich in mafic minerals. Main compositions of minerals are olivine, pyroxene and little hornblende. Rocks are formed by the products of mantlederived magma upwelling along the tectonic fissures and expansion and filling products in ancient weak belts. Its exquisite patterns have close relation with magma crystallization fractionation and late metamorphism. |
