Contrasting styles of Proterozoic crustal evolution: A hot-plate tectonic model for Australian terranes

McLaren, Sandra; Sandiford, Michael. A; Powell, Roger

Description

Proterozoic terranes in Australia record complex tectonic histories in the interval 1900-1400 Ma that have previously been interpreted by means of simple intracratonic or plate-tectonic models. However, these models do not fully account for (1) repeated tectonic reactivation (both orogenesis and rifting), (2) mainly high-temperature-low-pressure metamorphism, (3) rifting and sag creating thick sedimentary basins, (4) the nature and timing of voluminous felsic magmatism, (5) relatively large...[Show more]
