User:Simland1993/sandbox/Transamazonian Orogeny

The Transamazonian Orogeny occurred during the Palaeoproterozoic (2.1-2.0 billion years ago) and was caused by the amalgamation of various microcontinents to form modern-day South America. Evidence for this orogenic event in the south of the Saõ Francisco Craton in the form of a fold-thrust belt and dome/keel sturctures suggesting the closure of a subduction zone, then followed by exhumation and collapse of a mountain chain.
