摘要
The different understanding of the definition of Kedao Group, strata position, and forming environment is the focus of debate over the past 10 years. Through the unit stratotype (section), standard facies model method, walter law, principle of overlap, principle of inclusions, principle of metamorphism, principle of stratigraphy, sedimentology, combining with recognized actual data about Kedao Group, discussed the focus of the debate. The conclusion is that Kedao Group is mainly composed of redeposit volcanic fragmental deposit and a little epicoutinental fragmental deposit, and with siliceous limestone and siliceous mass. In this paper, the authors studied stratigraphy by theoretical stratigraphy and principle of sedimentology in the study area.
