“The role of subduction in the formation and evolution of continental slivers and microcontinents” and aims to identify how subduction-related processes affect continental margins, and how feedbacks between inherited structures and subduction may lead to microcontinent formation (ESR9)
Classical scenarios of microcontinent formation refer to continental rifting followed by seafloor spreading and subsequent mid-ocean-ridge relocation that results in the detachment and isolation of continental blocks. However, several generations of microcontinents have been formed in the Iapetus and Tethys domains in the Palaeozoic and Mesozoic, and in the Mediterranean more recently (e.g. Corsica and Sardinia since the Miocene), due to slab pull and rollback, trench relocation and subduction polarity changes. To unravel the dynamic relationship between microcontinents and subduction dynamics the project will examine two cases: (1) one from an ancient margin that preserves microcontinents as accreted terranes and (2) a modern oceanic basin that preserves microcontinents formed by subduction. The project will combine field observations with plate kinematic models and dynamic forward models.
