| 摘 要： | 湘中龙山穹隆是一个复合成因的穹窿。加里东期表现为共轴而非等势挤压造山，印支期经历了非共轴而等势的挤压造山。早期的构造样式为北东向的紧密线性倒转褶皱，晚期的构造样式为北东向的短轴背斜。

TECTONIC EVOLUTION OF LONGSHAN DOME IN MIDDLEHUNAN |

| Abstract: | Longshan dome in middle Hunan is one with composite cause of formation.In Caledonian epoch,the dome experienced coaxial and unequal compression orogeny movement and in Indo-Chinese epoch,it shows uncoaxial and equal compression orogeny movement.Early,the tectonic style is a series of northeastern linear upset appressed fold and late the tectonic style is a northeastern brachyanticline. |
