A comprehensive tectonic evolution of Proterozoic to Cambrian rocks that integrate the
crystalline basement of Rio de Janeiro State, based on the new geological map, is …

In this contribution, we report new PT (pressure–temperature) and U-Pb zircon
geochronological data from the Lima Duarte Nappe and basement rocks from the …

Abstract New U–Pb and Lu–Hf zircon data for the Andrelândia Group are presented and
discussed with the previously published data to propose an evolutionary model. The …

Abstract Terranes of the Neoproterozoic Ribeira Belt record processes related to West
Gondwana assembly. However, the evolutionary history of the belt in the preceding Rodinia …

Records of Precambrian glaciation have been reported from southeastern Brazil for over a
century. We present sedimentological, stratigraphic and isotopic (U-Pb and Lu-Hf on detrital …

Collisional orogens are one of the most conspicuous features of plate tectonics on Earth.
They record the dynamics of continent-continent amalgamation, often confined to linear …

Two metasedimentary successions, the Paleoproterozoic Itapira Group and the
Neoproterozoic Andrelândia Group, are present in the southwestern extreme of the …

New data are presented related to the evolution of major shear zones in the Neoproterozoic
Southern Brasília and Ribeira orogens, considering their attitude, kinematics and …

The Neoproterozoic Brasiliano-Pan-African Orogeny led to the aglutination of blocks that
formed West Gondwana (Fig. 1a). In this context, detailed structural mapping, microtectonic …

Studying sedimentary provenance within orogenic belts provides critical insights into
continental crust evolution and tectonic models. However, the deformation and …
