Project Details
Description
The Arabian-Nubian Shield (ANS) is one such tectonic collage of late Neoproterozoic (ca. 850 to 600 Ma) island arc terranes, representing the northward extension of the East African Orogen, which formed during the final amalgamation of East and West Gondwana generating the Gondwana supercontinent.
In the Arabian Shield part of the ANS, the western arc terranes, which are primarily exposed in the west of Saudi Arabia and Yemen, were formed and assembled at ca. 800-700 Ma, while the eastern arc terranes are somewhat younger at ca. 740-620 Ma. These eastern expoures occur in Oman, in the Salalah-Marbat area, Jebel Jaalan, Joba, Qalhat, and in the Hallanyat islands. In this study, we will carry geochronological and geochemical work on the rocks of the Hallanyat islands to understand the isotope character and geochemical signature of Neoproterozoic rocks exposed to better
understand assembly of the Arabian plate within the ANS context
