TS Must-Read – Platt (1986): Dynamics of orogenic wedges and the uplift of high-pressure metamorphic rocks

Orogens are the locus of intense deformation and metamorphism, mainly caused by convergent tectonics and burial. Yet, deeply buried rocks – metamorphosed at high pressure (HP) – are customarily met at the surface, even in “recent” systems such as the Alps. The long-standing question is naturally “how are these rocks brought back to the surface?” At the time John Platt wrote his manuscr ...[Read More]

TS Must-Read – Dewey and Bird (1970) Mountain belts and the new global tectonics

Long after the first attempts made by Wegener (1915)⁠, the theory of plate tectonics was progressively accepted by the Earth sciences community in the thrilling ‘60s thanks to observations from mid-ocean ridges (see TS-must-read blogpost of September 2, 2020; Dietz, 1961; Heezen and Tharp, 1965, Hess, 1962; Vine and Matthews, 1963)⁠. The question is then, what goes on at convergent boundaries, whe ...[Read More]
