【摘要】 推导出计算沉积物压实量的理论公式：Δｈ＝ｈ（ｎ０－ｎ）／（１－ｎ０）．指出造成海岸堆积平原中Ｑ２３海相顶面高程常比岩岸地面上的古海面遗迹的高程低数米至数十米的主要因素：①沉积物压实；②冰期低海面流水蚀低古地面；③局部构造下沉．逐步分解出这３个因子就能较正确确定古海面高度、古地形起伏和构造下沉量更多还原

【Abstract】 Theoretical formula for sediment compaction capacity Δh=h(n 0-n)/(1-n 0) is infered. Main factors resulting in tops leight of Q 2 3 sea facies in coastal accumulation plains is lower metres to tens metres than remains leight of paleo sea level on rock coast are:1 compaction of sediments,2 paleo landform is eroded and droped by running water in low sea level in glacial epoch;3 structure dropping in some areas. The three factors have been progressively resolved,paleo sea level,rise and fall on the paleo landform and capacity of the structure dropping can right have been define.更多还原
