Fig. 1From: The Makkah–Madinah Transform Zone: a relic rift-to-rift continental transform formed during early Arabia–Nubia plate separationPresent-day tectonic setting of the Arabian margin (modified after Aldaajani et al. (2021a, b)). This map shows the changes extensional style along the Red Sea. The region of diffuse extension, and the MMTZ, which bounds the diffuse grabens and dike intrusions to the south is shown. The MMN volcanics are outlined in dark green. The central Red Sea transforms and curvature region show potential spatial correlation with the MMN volcanics regionBack to article page
