| 摘 要： | 闽北浦城地区广泛发育前震旦系麻源群变质岩，其内发现条带状花岗片麻岩，前人将其划归混合岩化变质地层，本文将其作为独立地质体详细论述其宏观及微观地质特征，确定其为花岗质正片麻岩，属中酸性深成岩体经受强烈变形变质作用产物，并正式命名为小串花岗片麻岩，时代属晋宁期。它为研究我省晋宁运动提供了重要资料。

| Abstract: | The pre-Sinian Mayuan Group metamorphic rocks have an extensive expeition to Pucheng area of Northern Fujian, where the banded granite-gneiss was discovered. The granite-gneiss was before grouinto the mismatized metamorphic strata, but in the poper it is taken as an independent geological body in accordance with its macroscopic and microgeological features. It is determined to a granitic orthogneiss, which results from the intensive deformaion and metamorphism of intermediate-acid plutons.Therefore, it is herein called Xiaochuan granite-gneiss, which belongs to the Jinning Period. The discov-ery of the Xiaochuan granite-gneiss will help the research of Jinning Movement in Fujian Province. |
