The Precambrian high-grade gneisses of a continental terrane and the late Proterozoic (Pan-African) low-grade volcanogenic oceanic assemblage of northeastern Nuba Mountains are separated by the Kabus ophiolitic melange. This zone reflects a structural style of imbricate thrusting and strata1 disruption that is attributed to the collision of the Pan-African oceanic assemblage of the Nubian Shield against the pre-Pan-African continental crust to the west. The geological, structural, geochemical…

Late Proterozoic magmatism in the Nakasib suture, Red Sea Hills, Sudan

The south-western part of the NE-SW-trending Nakasib suture in the Red Sea Hills of Sudan is characterized by a distinct lithostratigraphic and geochemical zonation from north to south. The southern

Tectonic evolution of the Nakasib suture, Red Sea Hills, Sudan: evidence for a late Precambrian Wilson Cycle

The Nakasib suture is a late Proterozoic (Pan-African) ophiolite-decorated structural belt in the central Red Sea Hills of the Sudan. It represents one of the sutures along which the island

Tectonometamorphic evolution of the Neoproterozoic Delgo suture zone, Northern Sudan

In the area around Delgo in north-east Sudan a narrow NNE-trending Neoproterozoic belt of low grade volcanosedimentary rocks is fringed by high grade migmatitic basement blocks. The

Tectonic framework of the Precambrian of Madagascar and its Gondwana connections: a review and reappraisal

The Precambrian of Madagascar is divided into two sectors by the north-west trending sinistral Ranotsara shear zone, which continues in the Mozambique belt, probably as the Surma shear zone, and in

Discussion of ophiolites in Northeast and East Africa: implications for Proterozoic crustal growth

W. R. Church writes: In discussing the Pan-African geology of Northeast and East Africa, Berhe (1990) affirms that ophiolite decorated lineaments in the Arabian—Nubian Shield represent suture zones.

The Boundary Between the Saharan Metacraton and the Arabian Nubian Shield: Insight from Ediacaran Shoshonitic Granites of the Nuba Mountains (Sudan): U–Pb SHRIMP Zircon Dating, Geochemistry and Sr–Nd Isotope Constraints

The Saharan Metacraton (SmC) is a fascinating continental-scale entity. However, its boundaries are not all well defined, which is the case to the SE in the Nuba Mountains, Sudan, here studied.



Crustal evolution in north-east and east Africa from model Nd ages

The relationships between the various crustal provinces that comprise north-east and east Africa are far from clear and reflect diverse tectonic and magmatic processes which took place during the

Geochemical evidence for the genesis and eruptive setting of lavas from Tethyan ophiolites

Most Tethyan ophiolites in the Mediterranean region fall into two categories: 1) fragmentary sequences of late Tri-assic to early Cretaceous age; and 2) fully-developed complexes. probably of late

Pan-African (late Precambrian) tectonic terrains and the reconstruction of the Arabian-Nubian Shield

The recognition of Precambrian ophiolite suites and their dismembered remnants in association with intraoceanic island-arc volcanic and plutonic terrains across much of the Arabian-Nubian Shield of
