Francois, C; Philippot, P; Rey, Patrice; Rubatto, Daniela

Description

Archean granitic domes and intervening volcano-sedimentary basins are commonly interpreted as the product of "sagduction", a process involving the gravitational sinking of surficial greenstone cover sequences into narrow belts and the coeval exhumation of deeper granitic crust into broad domes. Alternatives to the sagduction model that can account for the regional dome and basin pattern include fold interferences and extensional metamorphic core complexes. In order to provide quantitative...[Show more]
