Many new high quality and high resolution geophysical and geological data have been acquired in recent years that enable us to up-date, re-analyze and re-interpret the subduction processes in the light of our present knowledge. Moreover we need to better clarify the Time and Space evolution of those processes to better precise our ideas on geodynamics of inversion tectonics, relations between Thick and Thin-skin tectonics processes (TTST), etc. that are important in a mountains building system.
Among many places, Taiwan is a key area to study such subduction to collision transition due to the rapid Eurasian to Philippine Sea Plates convergence. In Taiwan, the east dipping Manila oceanic subduction, that evolves northward, first, into a continental subduction (or called collision) onshore Taiwan, then into the north dipping Ryukyu subduction east of Taiwan. Due to the fast Plates shortening rate (10 cm/y), the active Oceanic to Continental Subductions processes in Taiwan create 1/8 of the annual seismicity in the World.
Other places in the world, active or not, should also be taken into consideration herein in order to reveal and lead us to better understand those tectonic processes (e.g. Alpes, Pyrénées, Cascades and so on).
In summary, we welcome contributions that could update the existing geodynamic concepts of the oceanic to continental subductions processes from new data collected recently and all the work that had been done on this subject to provide a better understanding on the processes of subduction to collision transition.
