摘    要：以东秦岭松树沟超镁铁岩体的产状和铬铁矿的产出特征为背景，结合铬铁矿 的组分特征, 对副矿物铬铁矿和不同矿石类型铬铁矿的穆斯堡尔谱进行成矿特征方面的 解释；并通过与铬铁矿形成有关的宏观和微观地质现象分析，指出铬铁矿体是地幔岩高度熔融形成的富铬和镁的极端部分。

Abstract: Based on the occurrence of Dongchinling-shonshugou ultramafic rock and the characteristics of the chromite mineralization as well as the mineral components, a comprehensive explanation of the mineralization characteristics of the various chromites, such as those of being as the accessory minerals and those of different types of ore, has been proposed through the analyses of Mossbaur spectra. In addition, the macroscopic and microscopic gelogical analyses of the mineralizatin of chromite leads to conclusion that the chromite ore body is actually the extreme portions of rich chrome and rich magnesium formed by the highly-melted pyrolite.
