Structural and geophysical signature of the Northern Portion (Ceará-Piauí border) of the Transbrasiliano Lineament: reactivation in the Parnaíba Basin

Geologia USP. Série Científica, 2015
The Transbrasiliano Lineament is a major shear zone trending NE-SW, related to the Brasiliano orogeny and evolved through high to low temperature stages.

The tectonic evolution of the Transbrasiliano Lineament in northern Paraná Basin, Brazil, as inferred from aeromagnetic data [PDF]

Journal of Geophysical Research: Solid Earth, 2014
AbstractData from six airborne magnetic surveys were compiled and analyzed to develop a structural interpretation for the Transbrasiliano Lineament in northern Paraná Basin, Brazil. Magnetic lineaments, interpreted to reflect geologic contacts and structures at different depths, were illuminated using the matched‐filter technique applied to ...

Tectonic Framework of the Arenópolis and Anicuns‐Itaberaí Segments of the Goiás Magmatic Arc Based on 3D Magnetotelluric Inversion

Geochemistry, Geophysics, Geosystems
The Goiás Magmatic Arc (GMA) is a Neoproterozoic juvenile terrain formed through oceanic‐oceanic and oceanic‐continental subduction. It comprises three main segments: Mara Rosa, Anicuns‐Itaberaí (GMAAI), and Arenópolis (GMAA), whose tectonic evolution ...

Magnetotelluric evidence of the tectonic boundary between the Río de La Plata Craton and the Pampean terrane (Chaco-Pampean Plain, Argentina): The extension of the Transbrasiliano Lineament

Tectonophysics, 2013
Abstract The Transbrasiliano Lineament represents a continental shear belt that transversely intersects the South American Platform from NNE to SSW. Much evidence of this lineament exists to the north, but it remains uncharacterized in the distal Andean foreland to the south, where it is associated with the tectonic boundary between the Rio de la ...

Thermal And Magnetic Context of Central Brazil Structures: A Study of Magnetic Lineaments in The Central Portion of The Transbrasiliano Lineament And Adjacent Regions

Brazilian Journal of Geophysics, 2022
ABSTRACT. Analysis of thermomagnetic features of the region in central Brazil based on aeromagnetic data. Edge enhancement techniques of anomalous magnetic field (AMF) were employed for this purpose. This approach has allowed the identification of magnetic lineaments in subsurface associated with structural features like the Transbraziliano lineament ...

Detrital zircon provenance and paleogeography implications for Furnas Formation in the northwest of Paraná Basin [PDF]

Geologia USP. Série Científica, 2015
In the northwest of the Paraná Basin, between the states of Mato Grosso and Goiás, there are exposures of the Furnas Formation, where the Transbrasiliano Lineament is also recognized.

Evaluation of the hydrocarbon generation potential of the Pimenteiras Formation, Parnaiba Basin (Brazil) based on total organic carbon content and Rock-Eval pyrolysis data

Energy Exploration & Exploitation, 2021
The Parnaiba Basin is a Paleozoic to Mesozoic intraplate volcano-sedimentary basin where the Pimenteiras Formation (Devonian) is the main sequence with potential of hydrocarbon generation, mostly natural gas.

Thermo‐Compositional Structure of the South American Platform Lithosphere: Evidence of Stability, Modification, and Erosion

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 11, November 2022., 2022
Abstract Constraints on the structure of cratonic lithosphere are essential to improve our understanding of craton formation, evolution and long‐term stability. Here, we perform a joint inversion for the thermal and compositional structure of the mantle lithosphere below the South America Platform, using Rayleigh wave group velocities, elevation, and ...

Geophysical evidence of pre-sag rifting and post-rifting fault reactivation in the Parnaíba basin, Brazil [PDF]

Solid Earth, 2016
This study investigated the rifting mechanism that preceded the prolonged subsidence of the Paleozoic Parnaíba basin in Brazil and shed light on the tectonic evolution of this large cratonic basin in the South American platform.
