简介：Wanan盆的延期和沉淀上的量的研究被执行基于可得到地震并且和地区性的地质的数据的地上凿穿数据。用平衡剖面图和backstripping技术，我们重建了stratigraphic免职和盆的构造进化历史。形成从的盆始新世并且除了晚中新世的本地人通常处于一个extensional/transtensional国家compressoin。在渐新世并且早的主要的盆延期ocurred中新世(在∼16.3妈前)并且处于更小的率的此后一致的段。北、中间的盆在38.6-23.3妈期间更早强烈地延长了，当南部的盆主要在23.3-16.3妈期间被拉长时。盆形成和发展与轮流出现有关对沿着Wanan差错地区的右罢工滑倒运动左首。主导的动力学可以被华南海传播的seafloor引起并且它的外部板相互作用。盆构造进化被划分成五个阶段：起始的rifting，主要rifting，裂缝飘移转变，结构的倒置，和热沉淀。

简介：北华南海架上的沙波浪被认为寡妇床形式同样稳定。为在车站LF13-2和LF13-1之间的海床的工业使用，探索的一个新回合被进行。沙波浪的间距和振幅都系统地与水深度正在改变的最新获得的数据表演。自从2003～2004证明海床当前是活跃的，重复了观察。由于表面沉积的强壮的侵蚀自从Dongsha()高举，Dongsha的架上有几乎不现代的沉积区域。在学习区域的沙材料主要从床沉积形成的侵蚀发源。水深度增长由更健全的数据主要由于侵蚀的重复回响揭示了。底部水流在Dongsha的区域是相当复杂的在水下高原。在地点9MKII，向南方退电流比强壮，向北方在地点AEM-HR充满电流，WNW病房洪水水流比ESE病房稍微强壮退当前。在地点9MKII，最大的底部水流速度是48cm/s，并且22%观察底部水流速度比20cm/s大，它遇见为沙波浪的创造要求的最小的底部水流速度。这篇文章指出今日的海洋学的状况与沙波浪形态学联合很好，并且沙飘动，这是在很大程度上在有进行中的今日的海洋学的底部水流的平衡调节并且活跃。
