摘　　要：万家岭锂矿是近年来鄂南地区发现的一处小型锂矿床。基于矿区普查工作,总结矿床地质特征并浅析矿床成因,指出下步找矿方向。结果表明,该矿床位于幕阜山岩体北缘、方山背斜核部,矿体呈脉状产出于近EW向F 9断裂破碎带中,含矿岩性为构造碎裂岩、碎裂板岩、变质粉砂岩和煌斑岩等,伴随硅化、褪色化等蚀变,矿石矿物为锂绿泥石。初步分析认为该矿床主要受近EW向断裂带控制,可能与南部的幕阜山岩体及区内冷家溪群变质岩存在成因联系,成因类型属构造蚀变岩型。指出已发现矿体的深部及西部走向方向、F 9断裂的次级平行断裂分布区是成矿有利地段,建议在这些地段部署进一步的勘查工作。Wanjialing lithium deposit is a small lithium deposit discovered in southern Hubei Province in recent years.Based on the survey work of the mining area,the geological characteristics of the deposit are summarized and the genesis of the deposit is analyzed,and the next prospecting direction is pointed out.The results show that the deposit is located in the northern margin of the Mufushan rock mass and the core of the Fangshan anticline.The ore body is veined in the nearly EW-trending F 9 fault zone.The ore-bearing lithology is tectonic cataclastic rock,cataclastic slate,metamorphic siltstone and lamprophyre.With silicification,bleaching and other alterations,the ore mineral is lithium chlorite.The preliminary analysis shows that the deposit is mainly controlled by the near EW fault zone,which may be genetically related to the Mufushan rock mass in the south and the metamorphic rock of the Lengjiaxi Group.The genetic type belongs to the tectonic altered rock type.It is pointed out that the deep and western strike direction of the discovered ore body and the distribution area of the secondary parallel faults of F 9 fault are the favorable areas for mineralization.It is suggested that further exploration project should be deployed in these areas.
