Subduction System Response to Ribbon Collision: Implications on the Intra‐Plate Force Balance and the Style of Slab Deformation

by
Figure 3 from Rodriguez‐Corcho et al. (2026)

Using three-dimensional numerical models, the authors investigate how a buoyant ribbon of thickened oceanic crust colliding with a subduction zone disturbs stress and strain within the subducting slab and the surrounding plates. They find that the angle of collision creates compartmentalised zones of high and low strain rate around a region of strong vorticity, and … Read more…

Tectonics: Modeling Lithospheric Thickness Along the Conjugate South Atlantic Passive Margins Implies Asymmetric Rift Initiation

by

The lithospheric architecture of passive margins is crucial for understanding the tectonic processes that caused the breakup of Gondwana. We highlight the evolution of the South Atlantic passive margins by a simple thermal lithosphere-asthenosphere boundary (LAB) model based on onset and cessation of rifting, crustal thickness, and stretching factors. We simulate lithospheric thinning and select … Read more…
