Late Ediacaran post-collisional magmatism in the Guera Massif, South-Central Chad

J. Gregory Shellnutt et al.

Summary: The study of the Guera Massif in South-Central Chad reveals the origins, ages, and chemical characteristics of collisional and post-collisional intrusive rocks. The findings suggest that the formation of these rocks is related to crustal thinning, partial melting, and regional tectonic deformation in the area.

The formation of Neoarchean continental crust in the south-east Superior Craton by two distinct geodynamic processes

D. R. Mole et al.

Summary: This study analyzed geochemical data from the southeast Superior Craton in Canada to investigate the continental crust formation and evolution in the Neoarchean era. The findings suggest a continental-rift setting driven by plume magmatism followed by a transition to north-dipping subduction, indicating the possible onset of plate tectonics around 2.7 billion years ago.

U-Pb-Hf isotopic systematics of zircons from granites and metasediments of southern Ouaddai: (Chad), implications for crustal evolution and provenance in the Central Africa Orogenic Belt

Felix Djerossem et al.

Summary: The study presents the first combined U-Pb ages and Lu-Hf isotope data of zircon grains from the southern Ouaddai area in Eastern Chad, providing insights into the crustal accretion and reworking history. The results indicate multiple magmatic events and metamorphic processes that shaped the geological evolution of the region.

Geochemical reconnaissance of the Guera and Ouaddai Massifs in Chad: evolution of Proterozoic crust in the Central Sahara Shield

M. J. de Wit et al.

Summary: The geologic evolution of central Saharan Africa is still unclear due to the unknown ages and compositions of the crystalline basement across the region. The area is considered as a Neoproterozoic region or an older North African shield reactivated and re-stabilized during the Pan African period. The Central Sahara Belt, part of the Great Central Gondwana Arc, consists of Neoproterozoic crystalline basement and continental calc-alkaline magmatic arc, with evidence suggesting detritus from the region was widely distributed across North Africa.
