Syn-rift magmatic characteristics and evolution at a sediment-rich margin: Insights from high-resolution seismic data from the South China Sea

The interaction between magmatic and extensional processes related to the formation of rifted margins has been and still is highly debated. The interpretation of magmatic additions, timing of onset and budget of magma during rifting remains controversial and poorly constrained. In this study we explore the emplacement of magmatic additions in a rift system with high sedimentation rates and a well-established stratigraphic framework and discuss the perspectives toward resolving some of these problems.
