拉硐超基性岩体位于青海省祁连县城东北约15 km处，面积约7．6 km2，岩性主要由蛇纹石化橄榄岩、蛇纹石化辉榄岩、蛇纹岩及纯橄岩组成，共发现157个铬铁矿小矿体，铬铁矿体成群出现，依据野外铬铁矿体分布范围，自西向东划分为10个矿带，通过对其中铬尖晶石取样分析研究，并与区内其他含矿岩体中铬尖晶石样品化验分析结果对比，确定该类岩体不同岩性组合带的找矿方向。

Ladong ultra basic rock bodies locates in about 15km from the eastnorth of Qilian county of Qinghai province.Its square is about 7.6km2 .Lithology includes peridotite to serpentine,serpentine pet-rochemical rock,serpentinite and dunite .157 small chromite ore bodies have been found,and chromium i-ron ore bodies appear in groups.According to distribution range of the chromium iron ore bodies,10 ore belts have been divided from west to east.Through analysis and study on chromium spinel samples,and compared with other ore bearing rock samples of chromium spinel,ore prospecting directions in different combinations from lithology of the rock have been determined.
