Petrography and Geochemistry of Urf suite from Aqaba complex, Southern Jordan

The Aqaba complex located at the south-eastern of Jordan, exposes coexisting mafic–felsic association typical of synto pre-plate collision magmatism. The bulk of the pluton is made of quartz monzonite, granite and granodiorite. New U–Pb zircon dating revealed a synchronous emplacement of the granite (605 ± 4.6 and 617±3.7 Ma), granodiorite (613 ±4.4, 612 ±3.6 and 611.8±4.9 Ma) and quartz monzonite (608± 5.4 Ma). The whole-rock geochemistry indicate that the source for the quartz monzonite, granite and granodiorites could have been a continental arc-derived from mantle sources and mature metagreywackes. Melting of this crustal material was subduction related , which could have been an enriched mantle-derived melt contaminated . The Aqaba complex is a part of a the Arabian-Nubian Shield (ANS) are juvenile in character, Neoproterozoic, including in addition five large plutonic suites ; Rahma , Darba , Rumman,Urf and Yutum suite. The genesis of these suites were likely induced by mantle-derived magma in the shallow crust while their spatially and temporally discrete emplacement at shallow levels was probably related to the (extensional) of lithospheric boundaries, which represent a feasible fertile source for such granitoids.
