  1. 研究区内广泛出露的太古代岩石属于迁西群麻粒岩,包括麻粒岩、紫苏花岗岩、辉石-斜长片麻岩、角闪岩等。

    The Archaean rocks widely exposed in the area studied belong to the Qian-xi Group of granulite facies , including granulite , charnockite , pyroxene ( and / or amphibole ) - plagioclase gneiss , amphibolite and so on .

  2. 主要矿石矿物为晶质铀矿、铀石,铀矿化主要富集在伟晶状花岗岩内黑云母集中区、伟晶状花岗岩脉与黑云母斜长片麻岩接触带处。

    Main ore minerals are uraninite and coffinite . Uranium mineralization is mainly present in the biotite-concentrated site within pegmatoid granite and at the contact between pegmatoid granite dykes and biotite plagiogneiss .

  3. 岩体北侧发育不完整的混合岩带。在岩体的周围常见有混合岩化的黑云斜长片麻岩残留体。

    There is a uncomplete migmatite zone in the north of rock mass and there are lots of relic body of migmatization biotite plagioclase - gneiss around it .

  4. 野外填图和室内分析表明,福建邵武南部神仙排一带存在一种条带状黑云斜长片麻岩及黑云二长片麻岩的花岗质正片麻岩。

    By afield mapping and analysis there are granitic orthogneiss composed of banded biotite plagiogneiss and biotite monzogneiss in the Shengxianpai area , southern Shaowu , Fujian Province .
