摘　　要：姜叶马铬铁矿产于雅鲁藏布江超镁铁质岩带的西段拉昂错岩体之中,为富铬型豆荚状铬铁矿。本文主要讨论姜叶马豆荚状铬铁矿的地质特征及找矿前景。根据对拉昂错岩体岩相特征分析、姜叶马铬铁矿区已发现的豆荚状铬铁矿带和矿点的研究、以及与西藏罗布莎和东巧铬铁矿床的对比,总结了矿体分布和赋存规律,指出该地区具有形成大型豆荚状铬铁矿床的成矿地质条件,呈示出良好的找矿前景。Jiangyema chromite deposit lies in the Laangcuo rock body of which locates in the western Yaluzangbujiang ultramafic rock belt. It is a sort of the Cr-rich podiform chromite deposit. This article mostly discuss prospect for the Jiangyema podiform chromite deposit and its gological characteristics in Pulan Country, Tibet. According to the analysis of the rockfacies characteristics of Laangcuo rock body, investigated podiform chromite belt and ore spots of which have been discovered in Jiangyema chromite mine area, compared with chromite deposits of Luobusha and Dongqiao in Tibet. In this paper summarized the rule of the ore bodies distribution and their occurrence. This area exists geological condition for forming podiform deposits on large scale and represents good prospecting potentiality.
