This magnificent fit, however, has since then proven problematic and later reconstructions have introduced various deformation zones along the shorelines to accommodate the northward-propagating break-up. Intra-continental rifts and deformations have also been introduced to subdivide both continental plates into sub-plates.
This impressive fit, however, has proven to be problematic over time, and later reconstructions have included various deformation zones along the shorelines to account for the northward-propagating break-up. Additionally, intra-continental rifts and deformations have been introduced to divide the continental plates into smaller sub-plates.
