On the pre-cambrian stratigraphy of Eastern Asia

Summarizing the past and recent data on pre-Cambrian System in Eastern Asia, it can be concluded that the pre-Cambrian System are composed of the sediments of having four cycles of sedimentation. It is also known that most of pre-Cambrian Systems known so far belong to either one of transgression facies or regression facies in the four sedimentation cycles. The pre-Cambrian Systems can be divided into four stages, that is, Sinian, Hutoan, Liahoan, and Taishanian stage. It is supposed that all pre-Cambrian Systems in Korea will belong to one of these four cycle sedimentations. Therefore, the reasonable way of study of Korean pre-Cambrian Systems is to investigate which stage they belong to.
