lang="EN-US">Based on application of the rock assemblage and more maturely regional tectonic - magmatic evolution, and define tectonic evolution. Bimodal volcanic rocks may occur in many geochemistry, the study attempted to analyze the spatial and temporal series of the regional different geodynamic environments, and the features of petrology and geochemistry of that are reviewed in this paper. It is suggested that the Bogda rifting started in the Early Carboniferous, ended in the end of Late Carboniferous or Early Permian and has difference from the spatial and temporal boundaries. It is inferred that the Bogda rifting of western began slightly earlier than the eastern, evolution of eastern rifting stronger than the western by the regional tectonic evolution, and east rifting may be closed earlier than the western.
