Paleozoic intraplate escape tectonics in Gondwanaland and major strike-slip duplication in the Lachlan orogen of Southeastern Australia

Intraplate tectonic escape along the eastern margin of Gondwanaland in Late Silurian to Middle Devonian time was caused by the eastward movement of Antarctica along a major intraplate tear. Resulting collisions caused a crustal block from the southern part of the Lachlan orogen of southeastern Australia to become detached from its lower lithosphere and escape to the northwest as a crustal flake. This escaping block then became incorporated into the western part of the Lachlan orogen as a separate terrane. -Authors
