This session focuses on continental collision, with an aim to understand the geodynamic processes of the subduction of rocks, continent collision and exhumation of the metamorphic core of the orogen including the subduction channel. Numerous studies of colliding continental plates show the complex interaction and feedback of processes related to the thermo-mechanical history recorded in pressure-temperature-deformation-time paths of the subducted and exhumed rocks. With modern analytical techniques, important parameters such as differential stress, strain rates, exhumation rates, kinematics, rheology, temperature and pressure can be revealed from selected rock samples from ancient and modern collision orogens such as the Alpine-Zagros-Himalayan chain, Caledonides, Variscides, or Grenville. In this session, we anticipate contributions from a broad spectrum of geoscientists, which focus on geodynamics of continent collision of ancient and recent collisional orogens.
