| 摘 要： | 研究波痕的重要意义,在于鉴定地层是否倒转,以确定区域地层层序。大连白云山发现在同一石英岩层内,正倒波痕共存,莫衷一是。根据北戴河海滩现代波痕的观察,即棱角明显正位分明已成型的涨潮痕,但在退潮时,因水动力条件和地形关系可以被改造,从而造成混淆。本文提出了鉴定方法。

| Abstract: | The common wavemarks in strata are often deformed under theinfluence of diagenesis and its various later stage factors so that the indentiflcation of wave marks nature becomes difficult. The production of wavemark is controlled by underwater topography as well as sediments size of which argillic silt material is the best. It' s necessary to carefully recognize original wavemarks namely peaks well preserved ones while those which have been reproduced cannot be used to judge and conclude by its deformed peaks and if the base rock on which wavemarks formed is force-pressed. We should pay attation to the effects of tectonis stress exerted on wavemarks. |
