摘要
裂谷盆地早期构造作用强烈,充填作用发生在由构造控制的盆地内。盆地的古地形通过物源区侵蚀和沉积物流的盆内输送而影响沉积体的类型与堆积样式。断裂的生长、传播、相互作用、连接与死亡控制了古地形的周期演化,对沉积体系的演化施加了强烈的影响或控制。伸展盆地地层发育的控制与过程的研究主要反映在断层的生长过程、裂谷盆地的侵蚀、汇水和沉积物流等方面的精细研究。此方面研究面临的问题不仅包括研究的精细程度和技术,而且包括相关分支学科的合作。
Tectonic activities were violent in the early stage of rifting and the filling occurred within basins controlled by faults. The paleotopographies of basin impacted types of sedimentary body and stacking styles through the erosion of source area and sediment flux to the basin. The cyclic evolution of paleotopographies controlled by growth,propagation,interaction,linkage and death of faults impacted the evolution of sedimentary systems. The study of processing and controlling in the stratigraphic development of extensional basins are documented by the precious studies in review of fault growth, erosion, catchment and sediment flux. The study is facing some problems at present,including study precision and technology,and cooperation of related subdisciplines.
