Stratigraphic records of the dynamic uplift of the Emeishan large igneous province

摘要: AbstractFluid dynamical and numerical modelling predicts a large-scale regional domal uplift prior to basalt eruptions in large igneous provinces, which can be readily measured when plume head rises below shallow marine sedimentary basin. Research on the sedimentology, biostratigraphy, isotopic chronology of Emeishan province demonstrates that environment Maokou stage is not uniform carbonate platform facies, but rather facies with north–south linear alignment west–east different distribution controlled by syn-depositional normal faulting Changhai Xiaojiang faults, are result underwater dynamic induced deep mantle activity. The started stage. Thus, thinning limestone was product difference initial depositional thickness caused post-depositional surface erosion, much less...
