Bill Collins (Curtin University) on: The critical role for water in the formation of continental crust

By Denis Fougerouse 15 November 2019 Applied Geology Comments Off on Bill Collins (Curtin University) on: The critical role for water in the formation of continental crust

Wed 20th November @ 11 am, Rm 312.222

Abstract:

The talk discusses how water modulates crustal temperatures during continental arc magmatism. It proceeds to show the role that hydrous basaltic arc magmas have in exsolving water during fractionation and underplating at the Moho, and consequently on melting the overlying crust.  A holistic petrological model is presented that focusses on the role of water through the subduction factory, from slab to surface, and how it facilitates the formation of continental crust.

 

Short bio:

Professor WJ Collins began his work on A-type granites at ANU with Bruce Chappell, before moving to La Trobe University for a PhD on Archean granites with Prof Allan White. A post-doc on high-grade Proterozoic terranes in central Australia ensued with Prof. Ron Vernon at Macquarie University before moving to the University of Newcastle as a lecturer. He moved to James Cook University as a Professor before returning to Newcastle as Director of the NSW Institute for Frontiers Geoscience. He became a Curtin Professorial Fellow last year.
