Institute of applied geology. lAG bull. Oxford This richly illustrated book provides an overview of the Neoproterozoic Pan-African Belt of Egypt (PABE), which represents the northwestern continuation of the Arabian-Nubian Shield (ANS) and the East African Orogen (EAO).

The Arabian-Nubian Shield (ANS) is the northern half of a great collision zone called the East African collision zone formed near the end of Neoproterozoic time when East and West Gondwana collided to form the supercontinent East African orogeny extends southward to the Mozambique Belt, and is a subset of the overall Pan-African orogeny.

The Arabian-Nubian Shield was formed over a relatively short period, which led Reymer and Schubert () to suggest an arc-addition rate of cu km/km-arc-length/million years.

This calculation assumes an area of 6 million sq km, a volume of million cu km, a. constitute the Nubian Shield that formed a contiguous part of the Arabian shield in the Arabian Peninsula before the opening of the Red Sea.

It is generally accepted that the basement of the Nubian Shield was cratonized during the Pan-African orogeny around Ma ago (El Gaby et al., ). The term ‘‘Pan-African’’ was introduced by Ken.

The oldest rock in the eastern flank of the Arabian-Nubian Dome is the Khamis Mushayt fundamental gneiss in the southern region of the Arabian Shield which has a distinct REE pattern and a pre Pan-African age older than Ma. The age of the oldest continental rock in this sub-plate is older than Ma, comparable to similar ages in Egypt.

Johnson Electronic publication date 21/2/ [DOI: /]. Evolution of the Nubian Shield in Egypt. The gold-bearing territory of Egypt lies within the north-eastern part of the African platform. Most of the territory is composed of rocks of the Nubian-Arabian shield.

The Arabian-Nubian Shield is located at the northern end of the East African orogenic area and is an extensive Neoproterozoic. During the last stage of the evolution of the Arabian – Nubian Shield, post-orogenic granite, dated between and Ma has been intruded [24].

Pohl [25] confirmed that the post orogenic lithophile element mineralization associated with A-type magmatism as well as gold –. This book offers a concise overview of the geology of Egypt in the context of the geology of the Arab Region and Northeast Africa, discusses the Paleozoic-Mesozoic-Cenozoic tectonics and structural evolution of Egypt and highlights the Red Sea tectonics and the Gulf of Suez and Gulf of Aqaba Rifts.

Here we present geological and geochemical evidence that the northern part of the Arabian Nubian Shield (Um Zariq Formation (UZF), southeast Sinai. the emplacement of post-orogenic gabbros and granites throughout the shield and the volcanism in the south.

The last stage of evolution in the Arabian-Nubian Shield (ANS) was the Late-stage sinistral wrench faulting [9], [10], [11], [13], and [25]. Fig. 1: Geological Map of the Area (Cottard, ). The depositional age of the Wadi Zaghra metasediments (Zaghra Formation) of the Sa’al-Zaghra metamorphic complex (Sinai) in the Arabian–Nubian Shield (ANS) has been constrained by LA-ICP-MS dating of zircons from (1) metaconglomerate granitoid clasts, (2) the metaconglomerate matrix, (3) biotite-schist, and (4) diorites and granites intruding the metasediments.

The Arabian-Nubian Shield was mainly formed over a relatively short period, which led Reymer and Schubert () to suggest an arc addition rate of km3 per km arc length per Ma (assuming an area of 6 km2, a volume of 3 km3, a Ma interval and an arc length of km).

Stern, Alfred Kröner, Renate Bender, Ahmed S. Dawoud. The West African Craton (WAC) is one of the five cratons of the Precambrian basement rock of Africa that make up the African Plate, the others being the Kalahari craton, Congo craton, Saharan Metacraton and Tanzania Craton.

Cratons themselves are tectonically inactive, but can occur near active margins, with the WAC extending across 14 countries in Western African, coming together in the late. The Hamadi gold deposit is located in North Sudan, and occurs in the Neoproterozoic metamorphic strata of the Arabian–Nubian Shield.

Two types of gold mineralization can be discerned: gold-bearing quartz veins and altered rock ores near ductile shear zones.

As a result, the gold ore may be used as a key to put more constrains on the late stage evolution of the shield.
