摘　　要：为探讨丘状交错层理的成因,在室内通过涡流运动的试验,发现在水盆中心区形成微微上凸、向四周缓缓倾斜的丘状沉积体。因此,提出丘状交错层理成因的新观点;同时,还应用圆周运动理论解释了风暴岩沉积序列的形成机理。For the cause of hummocky cross-stratification,there was no experimental method to validate it by predecessors.Through a laboratory experiment of eddy current movement,it was found out that the moundy deposit slightly convexed upwards and slightly inclined around and formed in the laver center.Thus the new viewpoint of the cause of moundy cross-stratification is put forward.At the same time,the form mechanism of the storm depositional sequence is also explained by using the circle movement theory.
