The flysch succession consists of trench-fill turbidites and associated carbonate conglomerates and olistostromes, which, together with the ophiolites, constitute an accretionary complex formed in a trench-forearc environment over a tectonically active, north-dipping subduction zone. Structurally, the evolution of this oceanic assemblage involved south-verging thrust faulting of the accretionary-prism and abyssal-plain deposits, as well as their underlying oceanic crust, resulting in the formation of a stack of off-scraped thrust slivers that later, down in the subduction zone, underwent redeformation and greenschist metamorphism. Obduction of the accretionary assemblage over the Iranian microcontinent took place prior to Late Triassic time. This content is PDF only. Please click on the PDF icon to access.
