Dear colleagues,
We would like to draw your attention to the following session at the next AGU Joint Assembly in Montreal (3 - 7 May 2015).
Crustal evolution in large hot orogens from pre-collisional continental margin through the collision and collapse stages: evidence from field, analytical and numerical studies
Large hot orogens (LHOs) are major sites of heat loss and recycling of continental crust. The tectonic evolution of LHOs has traditionally been considered in terms of processes during the formation of double thickness crust under an orogenic plateau, but recent work suggests it is also influenced by the pre-collisional history of the margins. In addition, gravitationally driven collapse and associated magmatism and fluid influx may exert important controls on the final crustal architecture. With respect to thermal structure, the origin and duration of the peak granulite-facies temperatures in the middle and lower crust of LHOs and their link to syn-orogenic magmatism remain incompletely understood.
This special session will feature contributions on recent modeling and field-based studies of the Grenville Province, an example of the exhumed roots of an LHO, but contributions from other LHOs such as the Variscan Belt and the Himalaya-Tibet Orogen are strongly encouraged.
