摘　　要：锂因具有“储能”、“生能”、“节能”的属性而被称作是“21世纪的能源金属”。华北地区具有相对良好的成锂条件,近些年锂矿找矿取得了一定的进展,在豫西地区发育有伟晶岩型锂矿床,在内蒙古维拉斯托外围发现了花岗岩型锂锡矿体。另外铝土矿中、煤田中也赋存有一定的锂资源,阿拉善地区盐湖卤水中也发现有锂资源的局部富集。本文概要介绍了华北地区典型锂矿床的地质特征,并对其成矿时代、成矿分布规律和矿床成因进行了总结。总体上,河南省花岗伟晶岩型锂矿的成矿时代为晚志留纪-早泥盆世,伟晶岩和成矿元素具有明显的空间分布规律,为过铝质LCT型伟晶岩,属于稀有金属(REL)类REL-Li亚类;内蒙古地区锂矿床形成于早白垩世,垂向分带明显,属于与钠质碱性花岗岩有关的稀有金属矿床。Because of its properties of"energy storage","energy generation",and"energy saving",the Lithium is called"the energy metal of the 21st century".The North China has relatively good conditions for lithium forma-tion.In recent years,some progress has been made in the prospecting of lithium deposits.Pegmatite-type lithium deposits have developed in western Henan,and granite-type lithium-tin deposits have been discovered outside the Weilasituo,Inner Mongolia.In addition,there are certain lithium resources in bauxite mines and coal fields.The salt lake brine in the Alxa area also has a local enrichment of lithium resources.This article briefly introduces the geological characteristics of typical lithium deposits in North China,and summarizes their metallogenic age,metallogenic distribution rules and genesis.In general,the metallogenic age of granitic pegmatite-type lithium de-posits in Henan Province is Late Silurian-Early Devonian.Pegmatites and ore-forming elements have obvious spatial distribution patterns.The pegmatites is peraluminous LCT pegmatites type,belonging to the REL-Li sub-category of the rare metal(REL)category.Lithium deposits in Inner Mongolia were formed in the Early Creta-ceous,with obvious vertical zoning,and belong to rare metal deposits related to albite alkaline granite.
