摘　　要：通过对武山鸳鸯镇铬铁矿的地层、构造、岩浆岩、矿体特征等地质特征分析,该矿床形成于鸳鸯镇超基性杂岩体中,赋存于蛇纹石化橄榄岩岩相中,近矿围岩为橄榄岩,矿体受断裂构造控制。本文对鸳鸯镇铬铁矿地质特征及矿床成因作初步探讨。Based on the geological characteristics analysis of the formation,structure,magmatic rock and orebody characteristics of Yuanyang Town chromite in Wushan,the deposit is formed in the ultrabasic complex of Yuanyang Town and exists in the serpentinized peridotite lithofacies.The surrounding rock is peridotite and the orebody is controlled by fault structure.The geological characteristics and genesis of the chromite deposit in Yuanyang Town are discussed in this paper.
