Session Description:
The Indochina peninsula offers a unique opportunity for understanding the transition from processes facilitating tectonic escape to those clearly related to subduction. The spatial and temporal evolution of these processes, in the context of India-Asia collision, include continent-continent collision, terrane mobilization and translation, oceanic basin development, and onset of subduction. Active escape of Indochina transitions to oblique subduction along Indo-Burma Arc, distally across the South China Sea, and to frontal subduction along the Luzon Arc. Comprehensive studies of Indochina may lead to a better understanding of the coupling of crustal and mantle deformation as well as the role plate boundaries play in both intra-continental orogenesis and marginal basin development. We invite contributions from different perspectives, including observations and analyses from:   seismology (seismicity, seismic imaging, attenuation and anisotropy), tectonics (tectonics, geodesy, geomorphology, stratigraphy, paleomagnetism, petrology, geochronology, geochemistry), fluvial development and dynamics, landscape development, and modelling (numerical and analogue).
