河南卢氏西南部花岗伟晶岩脉成矿特征

通过对河南省卢氏县西南部410 km2范围内的花岗伟晶岩脉群进行系统的大比例尺矿脉调查，初步掌握了该区域内矿脉体的分布特征及成矿特性，总结了花岗伟晶岩型稀有金属、铀、非金属矿产的成矿特征及成矿规律。结果表明，加里东末期岩浆活动形成的灰池子黑云母花岗岩体为该区域内花岗伟晶岩脉群的母岩，伟晶岩脉群因岩浆结晶分异及交代作用富集形成了稀有金属、铀、非金属矿产。

Mineralization Characteristics of the Granite Pegmatite Dyke in Southwest Lushi of Henan Province

The dyke distribution characteristics and metallogenics features of the research area are obtained and the mineralization characteristics and metallogenic regularities of the granite pegmatite type rare metals,uranium,non-metallic minerals of the research area are discussed based on conducting the large scale investation on the granite pegmatite dyke within the scope of 410 km2 in the southwest of Lushi county in Henan province.The research results show that,the ash pound biotite granite rock mass formed in the late caledonian magmatic activity is the parent rock of granite pegmatite dyke groups in the research area,the rare metals,uranium,non-metallic minerals are formed by the granite pegmatite dyke groups under the conditions of magmatic crystallization differentiation and metasomatism.
