With the rich sediments supplied by the Pearl River, under the paleogeography sedimentary background of Baiyun Sag continuously subsiding, with sedimentary sequences related to relative transgressive sea level change ,contrary to regressive eustasy, the Pearl River Deepwater Fan System has specific evolution characteristics, which left the sedimentary record controlled by peripherical significant geological events. The sharp change of deposition rate and lithologic geochemical characteristics about 23.8Ma sequence boundary demonstratesd that sediment source had changed, perhaps related to the uplift of Tibet plateau and spreading of the South China Sea, which led the paleoPearl River drainage to expand to western China plateau , maybe much broader than present.

珠江深水扇系统以珠江为沉积物源、以持续深沉降的白云凹陷为沉积古地理背景、以与全球海退型海平面相反的相对海侵型海平面变化的沉积层序构成了其发育演化的特殊性，并留下了控制沉积的周边重要事件的记录。23.8 Ma等界面沉积速率和岩石地球化学特征均有突变，反映出物源区的变化，可能折射出与青藏高原隆升、南海扩张有关的重要事件，使得古珠江骤然向西部高原拓展，甚至较今天的珠江流域范围还广阔；承载珠江深水扇系统的白云凹陷持续沉降形成了陆坡内盆地，导致21~10.5 Ma BP多个层序深水扇垂向叠置充填的特殊沉积建造；根据60多口井资料建立的相对海平面变化曲线，具有与全球海平面变化相一致的三级旋回和不一致的二级旋回。

The eustasy explanation put forward by Rona is also possible .

罗纳提出的海面升降也是可能的。

Lithology changes of Qom formation were controlled by eustasy change.

海平面升降旋回变化控制着Qom组内部各段岩性变化。

It is proposed that clear definition and discrimination of some relevant concepts and relationships on sea level and sea level change, eustasy and relative sea level, high frequency sea level and composite sea level, sea level rising falling, sea level fluctuation and sea level oscillation, sea level change and transgressive ...

对利用沉积记录来研究海平面变化的重视程度很高，但对海平面变化对沉积盆地的影响注意甚少。建议关注海平面升降变化对盆地充填物的作用，对沉积型矿床的控制和对大陆边缘地壳变形的反弹作用过程的研究及定量模拟是一个重要方向，它可能为大陆边缘动力学研究提供一方面的思路。

eustasy：海面升降

1906年 休斯(E.Suess)提出(全球)海面升降(eustasy)理论 认为沉积物增加会引起全球性海面上升;地壳沉降形成洋盆时 则引起海面下降. 意指 海进和海退是洋盆容积变化的结果 全球性海面变化并不包括海水量的增减.
