Tectono‐stratigraphic evolution of the rift and post‐rift systems in the Northern Campos Basin, offshore Brazil

open access: yesBasin Research, Volume 34, Issue 5, Page 1655-1687, October 2022., 2022
The rift system of in the North of Campos Basin records two distinct rift phases (RP1 and RP2). The RP1 and therefore the onset of rifting is interpreted to have occurred in the Berriasian. Abstract The Campos and Santos Basins have been a focus of subsurface studies since the discovery in 2006 of large accumulations of hydrocarbons in the Early ...

Paleomagnetic Constraints From 925 Ma Mafic Dykes in North China and Brazil: Implications for the Paleogeography of Rodinia

open access: yesJournal of Geophysical Research: Solid Earth, Volume 127, Issue 9, September 2022., 2022
Abstract Coeval Neoproterozoic mafic dykes with a well‐constrained isotopic age of 925 Ma are distributed in the North China Craton (NCC) of China and São Francisco Craton (SFC) of Brazil. Several recent studies favor the hypothesis that these two cratons were connected during 925 Ma and constituted building cratons for the supercontinent Rodinia ...

Transition from contractional to transpressive tectonics: evidence from the Feira Nova Region, Rio Capibaribe Domain, Borborema Province, NE Brazil

open access: yesBrazilian Journal of Geology, 2021
Differences in tectonic style and kinematics in orogenic belts can result from either multiphase or progressive deformation. In eastern Borborema Province, a regional shallow dipping foliation is multiply folded and crosscut by transcurrent shear zones ...
