The tectonic evolution of the Neoproterozoic Arabian-Nubian Shield (ANS) is widely held as
an example of crustal growth processes. The ANS consists of continental crust formed prior …

The growth of continental crust through melt extraction from the mantle is a critical
component of the chemical evolution of the Earth and the development of plate tectonics …

Abstract The Neoproterozoic Arabian-Nubian Shield (ANS) consists of continental crust
formed prior to and during the collision between East and West Gondwana. The Eastern …

Abstract The late Neoproterozoic–Cambrian interval is characterized by global-scale
orogenesis, rapid continental growth and profound changes in Earth systems. Orogenic …

The Paleozoic tectonic evolution of the northern margin of Gondwana is inferred to comprise
several episodes of continental breakup and ocean opening. However, the timing and …

Ophiolite nappes, encompassing dismembered oceanic lithosphere sections, in the Eastern
Desert of Egypt are mainly confined to Tonian-Cryogenian inter-terrane sutures. A cohesive …

Constraining the processes associated with the formation of new (juvenile) continental crust
from mantle-derived (basaltic) sources is key to understanding the origin and evolution of …

Abstract The Arabian Nubian Shield (ANS) is one of the largest juvenile continental crusts
formed after the Archean. To determine the timing and understand the mechanism of its …

The reworking of continental crust in collision zones is a key process in the chemical
maturation of crustal rocks. However, the mechanisms that cause crustal reworking remain …

The Khashir gabbro-granitoid suite represents a bimodal intrusive complex exposed in the
northern part of the Arabian-Nubian accretionary orogen. The gabbro is composed mainly of …
