| 摘 要： | 大巴山造山带及其前陆盆地的构造特征具有显著的分带性，按不同褶皱型式和变形强度可划分为若干构造带。逆冲推覆和褶皱作用均从大巴山外侧向前陆盆地方面呈递进运移扩展。根据对沉积充填与相邻大巴山造山带隆升之间的关系，重建了前陆盆地的构造演化。大巴山造山带及其前陆盆地具有广阔的含气远景。

| Abstract: | The tectonic features of Dabashan orogenic belt and its foreland basin slow obvious zonation.They can be divided into some tectonic zones based on different fold patterns and the deformation intensity.Both of the thrustings and the foldings progressively transferred form the outside of Daba Mts.towards the foreland basin.The tectonic evolution of Dabashan foreland basin is reconstructed by studying the relationship between the sedimentary fill sequence and the uplift of adjacent Dabashan orogenic belt.There is a broad prospect for natural gas in the area. |
