前发风暴液化沉积的概念,做稍许的改动:
风暴液化沉积(Storm liquefaction deposits):是指在浅海区,海床土体由于风暴浪的作用而形成液化,液化土体随风暴浪波动而出现颗粒分选,从而在土体液化区的原地形成具有递变层理和旋卷层理等沉积构造的重构地层的一种风暴沉积模式。该模式区别于以水平风暴流携带泥沙具有异地搬运特点的风暴沉积模式,是风暴沉积模式的补充。

Storm liquefaction deposits is a kind of stormdeposits model which occurs in coastal areas. Storm wave-induced liquefaction ofseabed soil leads to its fluctuation and grain-separation along with waves,thus a reconstructed stratum of sedimentary structure such as graded bedding andconvolute bedding is developed in the original liquefied position. This isdifferent from the model of storm flow transporting sediments at a longdistance.(References: WANG Xin;XU Guohui;SUN Yongfu;HU Guanghai;YU Yueqian;LINLin.

2015年申请的国家自然科学基金项目,承蒙各位评审专家厚爱,获批立项执行,感谢各位同行的鼓励支持!在后续的研究工作中,一定把“风暴液化沉积”这个小文章做得精细、精致!
