Sequence stratigraphy and tectonic framework of the Parecis Basin Mesozoic interval- a novel proposition.

This paper presents a novel Stratigraphic and Tectonic Framework for the Mesozoic Register of the Parecis Basin, using the concept of Supply Generated Sequences. The tectonic evolution of the South American Platform during the Mesozoic was utilized to establish the significance and correlations of the proposed Parecis Sequences 1 to 4 and their bounding surfaces. Parecis Sequence 1 exhibits a complete Transgressive Regressive Climatic Induced Clastic Behavior, with a depositional age from the Juro-Triassic period, related to localized deposition in an extensional regime caused by the CAMP event. A non-depositional/erosional gap of 90 million years between Parecis Sequence 1 and 2 is attributed to regional uplift associated with the Juruá Orogeny until the Late Cretaceous. Parecis Sequence 2 displays a complete Transgressive Regressive Climatic Induced Clastic Behavior and is associated with the Mochica phase of the Andean Orogen. Parecis Sequence 3 displays a complete Transgressive Regressive Climatic Induced Clastic Behavior correlated with the Peruvian phase of the Andean Orogeny. Parecis Sequence 4 considers the Rio Tapirapé Formation as a probable fourth sequence, with lake register and age defined by Coniacian notosuchian fossils. The Parecis Supersequence comprises Sequences 2 to 4, representing a trend of basin fill from Albian to Coniacian in a back-bulge foreland basin. • Supply Generated Sequences are used to explain climatic control clastic behavior in the Mesozoic register of the Parecis Basin. • The novel sequence stratigraphy framework defines four third transgressive-regressive sequences. • Parecis Sequence 1 registers the triassic-jurassic sequence related to CAMP and Penetecaua magmatism. • Parecis sequences 2 to 4 conforms the Parecis Supersequence, registering fluvial-aeolian deposits with attributed age from Albian to Coniacian.
