The Bajgan Complex revealed as a Cretaceous ophiolite-bearing subduction complex: A key to unravel the geodynamics of Makran (southeast Iran)

In the Makran area, a wide accretionary wedge is originated by north-dipping subduction of Neo-Tethyan oceanic lithosphere. The rear represented North Domain that consists an imbricate stack tectonic units derived from closure basin. This basin opened southward Eurasia continental margin during Early Cretaceous. Bajgan Complex interpreted as Paleozoic or older metamorphic basement representing remnants Bajgan-Durkan microplate located at southern rim plays thus key-role in so far proposed reconstructions evolution whole area. Late Jurassic to Cretaceous meta-ophiolites and related meta-sediments, both affected HP-LT metamorphism. metamorphism has been overprinted epidote amphibolite greenschist facies progressive exhumation up shallow structural levels. incompatible trace elements ratios meta-igneous rocks indicate subduction-unrelated chemical affinity for these meta-ophiolites. Our study clearly indicates cannot be considered pre-Mesozoic age. Consequently, collision between microcontinent Lut Block.
