Unzipping the subduction plate boundary: a journey through rocks and rheologies
FRANCIS BIRCH LECTURE
tectonophysics | 13 december 2023
Philippe Agard
Rocks once buried deep in the crust or lithosphere are direct probes of geodynamic environments and processes. As such, fragments of ancient oceanic l...
