At Hadhb't Ad-Dayheen, in the central Arabian Shield, a post-collisional igneous complex called Ad-Dayheen intrusion is exposed. It was emplaced Early Ediacaran (613–625 Ma), during final tectono-magmatic stage of Shield development. Despite limited and discontinuous ring-shaped outcrops due to alluvial cover later faulting, three pulses can be recognized field: an early pulse monzogranite; sec...

Detailed structural geological and related studies were carried out in a number of critical areas in the Proterozoic basement of eastern Egypt to resolve the structural pattern at a regional scale and to assess the general characteristics of tectonic evolution, orogeny and terrane boundaries. Following a brief account of the tectonostratigraphy and timing of the orogenic evolution, the major st...

A comprehensive remote sensing survey of AlUla County in north-west Saudi Arabia has revealed 32 examples the ancient, stone-built animal traps known as ‘kites’. Noting that most (27) are located on Ḥarrat ʿUwayriḍ, a satellite parts lavafield outside was undertaken, identifying further 175 kites. These show commonalities with ‘V-shaped’ kites previously identified mountainous areas along weste...

The Arabian Shield, which contains a group of diverse terranes accreted during the Late Proterozoic, has experienced considerable historical and recent earthquake activities. From north to south, Midyan terrane, Tabuk-Neom area, Hijaz Jeddah Asir terrane make up western section shield. In order determine occurrences recurrence characteristics in study an dataset containing 2,991 seismic events ...
