Magmatism and continental crust evolution in collisional zones

Session ID#: 75561

Session Description:
The Earth’s continental crust is on average of andesitic composition and formed as a result of multiple processes in magmatic arcs. Continental collisional zones preserve a secular magmatic record during and after continental collision in addition to arc magmatism generated during subduction of oceanic plates. Collisional processes not only expose the deep roots of the old magmatic arcs but also cause reworking and recycling of these rocks in the form of new magmatism, resulting in the stabilization of the continental crust. Collisional zones are therefore ideal regions to understanding of the fundamental problem in Earth Sciences — how does the continental crust evolve from a mafic to andesitic average composition and become stable as the collisional process evolves? We invite a broad range of field, petrological, geochemical, experimental, geophysical, and modeling studies related to the magmatic processes and crustal evolution in collisional zones.
