U–Pb zircon data from a felsic gneiss located at the contact zone with the central peridotite body of Zabargad Island (Red Sea, Egypt) provide an age of 23.2 ± 5.9 Myr consistent with the ^238^U–^206^Pb age of the youngest concordant grain (22.4 ± 1.3 Myr). Concordant grains indicate new zircon grow
