Zircon is a principal source of zirconium and hafnium, as well as a key mineral both for
petrogenetic modeling and age dating. Although zircon occurrences have been reported …

A fragment of continental crust has been postulated to underlie the young plume-related
lavas of the Indian Ocean island of Mauritius based on the recovery of Proterozoic zircons …

Madagascar occupies an important location within the East African Orogen (EAO). The EAO

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

The Neoproterozoic tectonic evolution of central Gondwana involved three successive
continental collisions, associated with the East African Orogeny (late Cryogenian), the …

Ancient orogens eroded to midcrustal levels provide insight into strain accommodation,
metamorphism and melting in Himalaya-type continent–continent collisions. This study …

The Ankaratra volcanic complex in central Madagascar consists of lava flows, domes, scoria
cones, tuff rings and maars of Cenozoic age that are scattered over 3800 km 2. The mafic …
