摘要

Abstract

The deep structure

material circulation

and dynamic processes in the Southeast Asia have long been an elusive scientific puzzle due to the lack of systematic scientific observations and recognized theoretical models. Based on the deep seismic tomography using long-period natural earthquake data

in this study

the deep structure and material circulation of the curved subduction system in Southeast Asia was studied

and the dynamic processes since 100 million years ago was reconstructed. It is pointed out that challenges still exist in the precise reconstruction of deep mantle structures of the study area

the influence of multi-stage subduction on deep material exchange and shallow magma activity

as well as the spatiotemporal evolution and coupling mechanism of multi-plate convergence. Future work should focus on high-resolution land-sea joint 3-D seismic tomography imaging of the curved subduction system in the Southeast Asia

combined with geochemical analysis and geodynamic modelling works.
