Paleoproterozoic evolution of Senegal in the Birimian Framework

, 2012
The whole of East-Senegal Birimian terrains have been investigated with a pluri-thematic approach combining airborne geophysics, field mapping, geochemical and isotopic data. Birimian Easternmost Paleoproterozoic terrains begins with the Mako Group of volcanics and metavolcanics, all assumed to have been emplaced at 2.20-2.18 Ga as a juvenile crust ...

Paleoproterozoic Reworking of Archean Crust and Extreme Back‐Arc Metamorphism in the Enigmatic Southern Trans‐Hudson Orogen

Geophysical Research Letters
The crustal evolution of the southernmost ∼2000–1800 Ma Trans‐Hudson orogen (THO) is enigmatic due to burial by Phanerozoic sediments. We provide new insights through petrochronologic analysis of a paragneiss drill core sample.

Zircon provenances of the late Paleoproterozoic metasedimentary rock in the South Yangtze Block: Implications for paleogeographic reconstruction

The zircon provenances of the late Paleoproterozoic metasedimentary rocks are important for assembling Proto-Yangtze and its reconstruction in the Nuna supercontinent.

O_2 constraints from Paleoproterozoic detrital pyrite and uraninite

, 2014
Redox-sensitive detrital grains such as pyrite and uraninite in sedimentary successions provide one of the most conspicuous geological clues to a different composition of the Archean and early Paleoproterozoic atmosphere.
