| 摘 要： | 利用水槽模拟实验定性观察和定量测量的方法探讨了断陷湖盆中沉积坡折带对于湖盆砂体沉积的影响及坡折带附近砂体的展布规律。结果表明沉积坡折带是沉积作用活跃的区带,它控制了新增沉积物在三角洲各亚相的分配,在坡折顶部和坡脚附近形成两个沉积物的富集区,形成砂体的有利发育区带;坡折角度是控制三角洲前缘滑塌的一个重要因素,三角洲中间位置向湖盆方向是三角洲前缘滑塌浊积体的有利发育区带;低水位时期坡折带控制了下切谷-低位三角洲沉积体系的发育。

| Abstract: | The effect of depositional slope-break belt on the deposition and distribution law of the sandy body in the rift basin has been researched by the method of qualitative observation and quantitative measurement in the flume simulation experiment.The result indicates that the depositional slope-break belt is the active depositional area.The depositional slope-break belt controls the distribution of the new sediment,the top and foot of the slope are two zones which are rich in new sediment.The angle of the slope is a key factor affecting the slip of the delta front,and the front zone of the middle area in the delta front is the advantaged zone of the fluxoturbidite;The depositional slope-break belt controls the development of sediment system of eroded valley-low stand delta. |
