Tectonic Magmatism

Investigate how plate tectonics drives magma generation and volcanic activity

Research Overview

Tectonic magmatism is a primary window into mantle–crust interactions, recording how melts ascend, react, and reshape the lithosphere. The differentiation of these magmas generates the chemical diversity of Earth’s crust and preserves vital clues about mantle source processes and tectonic environments.

Main Findings

We couple petrological–thermomechanical simulations with magmatic melting processes to examine lithospheric melting and its surface lithological expression during slab break-off. Our results indicate that in the early Earth, when mantle temperatures were relatively higher, shallow slab break-off could generate significant lithospheric melting and potentially give rise to Proterozoic massif-type anorthosites.
