| Abstract: | The relation and unity of the tectonic process and sedimentation is being paid a good deal of attention. It is very obvious that the sedimentary process of the terrestrial basin is controlled by tectogenesis. The sedimentary evolution of the basin is the reflection of the tectonic evolution . The sedimentary process of the terrestrial basin has unique characteristics.(1) The scope of the terrestrial basin is mainly controlled by the fault zones.(2) The regional tectonic cycle obviously controls the sedimentary sequence boundary of the terrestrial basin. The periodicity of tectogenesis causes the periodic change of the sedimentary sequence.(3) The sedimentary model of the terrestrial basin is obviously controlled by the tectonic framework.(4) There are many surprise sedimentary events in sedimentary formation of the terrestrial basin.(5) Owing to the influence of the tectonization, the deformation frequently occurs in the sedimentary deposit.(6) Because the sediments of the terrestrial basin have the short\|distance transport, the sediments have the low mature index.(7) There are more sedimentary centres, more matter\|sources, narrow sedimentary facies\|zone and the quick facies change in the terrestrial basin.According to the background of the tectonic dynamics, the terrestrial basin can be divided into the extension basin, the compression basin and the shear basin. The three basins differ greatly in the sedimentary characteristics. The extension basin is usually directed at rift basin. The border of the extension basin is mainly the normal fault or growth fault. The plane shape of the extension is zone\|shape. The sedimentary deposit of the extension basin has not strong deformation. The thickness of the sediment on the downthrow wall is greater than that the sediment on the upcast wall. The periodic change of the tectogenesis causes the enlarging or the contract of the extension basin. |
