Neoproterozoic crustal growth in the Arabian-Nubian Shield

Late-Precambrian volcanic rocks and dragon blood trees, Socotra Island, Yemen.

Late-Precambrian volcanic rocks and dragon blood trees, Socotra Island, Yemen.

Summary

The Arabian-Nubian Shield, which stretches from north-eastern Africa across the Arabian peninsula, represents one of the most significant volumes of Neoproterozoic crustal growth on Earth and, as such, is a key region for understanding tectonic and magmatic processes in the late Precambrian as well as the likely distribution of continents prior to the assembly of Gondwana during the so-called Pan African orogeny.

This project focusses on providing new geochronological constraints on magmatism across the shield as well as investigating the role of earlier micro-continental fragments in the assembly of the shield. Additionally, we are investigating the provenance of the Cambro-Ordivician “sand sea”, a vast fluvial deposit on the eroded Precambrian peneplane.
