Geochemistry of the Late Neoproterozoic Hadb adh Dayheen ring complex, Central Arabian Shield: Implications for the origin of rare-metal-bearing post-orogenic A-type granites

► The Hadb adh Dayheen ring complex (HDRC), comprises alkaline to peralkaline granites. ► Field and textural observations indicate that HDRC formed at different stages. ► Textural and chemical characteristics show primary and secondary metasomatic effects. ► Geochemical characteristics indicate that the HDRC granite has a post-orogenic A-type affinity. ► Magma that formed the HDRC may have originated by partial melting of underplated juvenile lower crust.
