Advances in deformable plate tectonic models (Part B): reconstructing the southern North Atlantic back through time

Abstract The offshore rifted margins of the North Atlantic have a spatially complex crustal structure comprised variable morphologies, continental blocks, and inherited structures. Recently, deformable plate tectonic models permitted interplay kinematics deformation to be assessed throughout Atlantic, elsewhere. In particular, ability calculate temporal variations in thickness has provided insight into kinematic role blocks their with large micro‐tectonic plates during formation margins. this study, modeling workflow introduced companion contribution study (Part 1) is used investigate previously published newly presented Newfoundland, Irish, West Iberian This approach permits subsequent evolution within recognized sedimentary basins southern Ocean visualized from 200 Ma present day. segmentation early rift thicknesses calculated by demonstrate strong correlations extension Appalachian Caledonian terrane boundaries. Thus, our observations suggest that orogenic boundaries potentially play key partitioning around blocks.
