【摘要】 在恢复古构造的基础之上,对比了松辽盆地南部十屋断陷营城组沉积时期的古构造格局与现今构造格局的异同。古构造对扇三角洲沉积体系的控制作用主要表现在:(1)主要基底断裂控制了扇三角洲的展布方向;(2)倾向与物源方向相反的断层和古地貌阻滞了扇三角洲的展布;(3)沉降中心控制了扇三角洲前缘的纵向叠置和发育。更多还原

【Abstract】 The ancient structural frameworks of the early deposition period of Yingcheng Formation have been compared with those at present in the Shiwu fault depression, southern Songliao basin based on the ancient structure reconstruction. The constrains of the ancient structures on the development of fan deltas of the Yingcheng Formation are represented by: (1) the extension direction of the fan deltas were controlled by the main ancient faults;(2) the development of fan deltas were blocked by the faults in which dip direction was opposite to the transportation direction of sediments and paleogeography;(3)the vertical overlap and development of fan delta front were controlled by subsidence center of the fault depression.更多还原
