【摘要】 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。本文以其产状、成分、所含包体、岩体变形特点及侵入关系为依据，论证它们是以片麻岩形式存在的古老花岗质深成岩体。神仙排花岗质正片麻岩的确认对闽西北乃至全省的早期地壳演化的探讨具有重要的意义。更多还原

【Abstract】 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. On the basis of the occurrence, composition, enclave-bearing, deformation freatare of rock mass, and intrusive relations, it is demonstrated that the granitic orthogneiss is the granitic plutonic palaeomass in the form of the gneiss. It has important significance of the affirmation of the granitic orthogneiss from Shengxianpai for inquiring into the early-crust ev0lution in the northwestern and even the whole Fujian Province.更多还原
