A multidisciplinary understanding of the formation and evolution of the continental lithosphere in collisional orogens
Session ID#: 83516
Session Description:
Continent-continent convergence is one of the most fundamental tectonic processes that has led to the growth and modification of the crust and mantle lithosphere on Earth. Continental collision creates the world’s major mountain ranges, such as the Appalachians, Alps, Himalayas, and Urals. The goal of this session is to advance our understanding of continental accretion and lithospheric evolution through geologic timeby bringing together geological and geophysical studies from a diversity of collisional environments. We invite contributions focusing on but not limited to the seismic characteristics of the crust and upper mantle, the identification and evolution of exotic terranes, the linkage of surface geology or magmatism with crustal/lithospheric structure, and deep mantle dynamics. We particularly encourage the contributions with integrative datasets, new methods, new models, and new ideas from multidisciplinary studies.
