北祁连拉硐超基性岩体铬尖晶石特征研究及找矿意义
摘要
Abstract
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.关键词
