During the Late Cretaceous to middle Paleocene (90 to 60 Ma), a 750-kilometer-long suture zone developed between the Apulian and the Rhodopian plates of Eastern Europe. The suture zone is located in present-day Romania, Serbia, and Bulgaria. This suture zone was developed as a result of B-type subduction. Thrusting was followed by strike-slip faulting with local extension. Dimitrijevic & Grubic (1977) and Popov (1987) postulated a continental rift setting in which andesitic lava flows and associated intrusions were emplaced in the zones of extension. We interpret that magmatism was focused at shallow crustal levels through the development of a series of extensional strike-slip fault duplexes that accommodated strain at many locations along the length of the suture zone
