| 摘 要： | 南祁连盆地石炭系海陆相沉积频繁交替出现,浅海相沉积突然大面积覆盖在下伏陆相沉积物之上,两者之间有明显的相序缺失,而且海相层在很大范围内具有明显的可追踪性与对比性,在横向上并无明显的相变关系,这样一种盆地充填特点,很难用经典的渐进型的海侵与海退模式来解释,似乎用快速“倒灌式”的海侵模式来解释比较合理。

| Abstract: | Marine sediment and land sediment alternately appeared frequently in Carboniferous of the South Qinlian basin The shallow marine sediment suddently covered the underlying land sediment in large range Facies sequence is obviously absent between them,and the marine bed is able to be tracted and compared obviously in large range,and the facies change is not obvious on horizon It is difficult to explain the filling characteristics with the classic gradual transgressive and regressive mode,while it seems more reasonable to explain it with the mode of fast"inverse-irrigation |
