沉积构造是非常重要的一种岩石成因标志。它可以反映岩石形成时期水介质搬运能力和搬运状态,物源成分的变化和古水流方向,甚至还可以间接地反映出沉积时期古气候变化,后期生物扰动和种种非构造运动的状况等等。然而,由于各种原因,有不少沉积岩没有直接显示形成时的上述种种烙印,因此,常使研究者感到困惑。基于这个原因,已有人试用各种研究手段对那些在沉积物的颜色、精度、 Sedimentary structure is a very important rock genetic marker. It can reflect the transportability and handling status of aquatic media during the rock formation, the change of provenance composition and paleocurrents, and even indirectly reflect the paleoclimatic changes during sedimentation, the late bioturbation and various non-tectonic movements. However, for a variety of reasons, many of the sedimentary rocks did not directly show the formation of these various imprinting, therefore, often confusing researchers. For this reason, a variety of research methods have been tried out to test the color, accuracy,
