| Abstract: | Through the study of sedimentary petrology of the marine beachrock of Rushan, including the indoor determination of microfosssils and big fossils, it is discovered that the rock body is characterized by the typical marine beachrock. In the rock body there are cementation materials consisting of two kinds of aragonite, microfossils of the marine beach facies assemblage and tropical marine fossil. The rock body was formed mainly in optimum climatic period of Holocene, at least with three rock-forming phases. It is of important scientific significance for the study of the regularity of palaeoenvironment changes. |
