摘要
东巧西岩体位于藏北蛇绿岩带的中段,是藏北湖区中较大的移置岩体之一。铬尖晶石作为副矿物产于超基性岩中。因其化学成分受控于形成时地质条件,且铬尖晶石在变形、变质条件下为较稳定矿物。本文以地质事实为基础,研究铬尖晶石成分变化,用以探讨成岩环境、岩体含矿性等问题。
Dongqiao western rockrnass located in middle of northern Tibet ophiohte, it is one ot the olgger dislocation rock mass. Picotite as the auxiliary mineral originate in uhrabasic rocks, chemical components controlled by the geological conditions of forming time. And picotite in the condition of transformation is steady mineral, this paper on the basis of the geology fact ,research on the ophiolite compositional variation, to discuss the diagenesis condition and rock mass ore-bearing potential etc.
