Subduction initiation during collision-induced subduction transference: Numerical modeling and implications for the Tethyan evolution

Intermittent Post‐Paleocene Continental Collision in South Asia

“…This buoyant oceanic plate does not have enough density contrast from the nearby continental terrane, leading to continuous flat subduction (Figures 2a–2c and 2) instead of a new subduction zone behind the terrane (Liu et al., 2021). This behavior is also related to the fact that we did not incorporate a weak zone between the ocean and continental portions within the incoming plate (Liu et al., 2021; Zhong & Li, 2020). Observationally, a single stable trench within South Asia as modeled here is consistent with the geologic records (Kapp & DeCelles, 2019).…”
