摘要
湖南连云山扁透镜状花岗岩侵位于长寿街—双牌走滑断裂带内。野外地质剖面观测结果表明 ,该岩区存在如下连续过渡的构造岩相分带 :未卷入断裂变形变质的冷家溪群 (围岩 )→含石榴子石云母石英构造片岩→混合岩化石英云母片岩→条带状、肠状混合岩夹透镜状花岗质小块岩→片麻状、块状黑云二长花岗岩 (主体 )。区域地质构造解析结果表明 ,连云山花岗岩与晚三叠世—侏罗纪 NNE向会聚走滑断层动热变质—剪切重熔型岩浆作用有关。
The lenticular granite of Lianyunshan in Hunan is located in the strike-slip fault zone of Changshoujie-Shuangpai.The field geological survey across the granite, shows that there are continuously transitional structural-lithofacie zones: Lengjiaxi Group (adjacent rock) without fault dynamic metamorphism→mica quartz tectonic schist bearing garnet→migmatitic quartz-mica schist→banded and ptygmatic migmatite including small rock masses of lenticular granite→gneissic and massive biotite monzonitic granite (hos...
