Regional Setting of Lachalan Fold Belt: Palaemagnetism and the Structural History of the Lachlan Orogenic Zone

Abstract

Comparison of palaeomagnetic and geological tectonic models of the Lachlan orogenic zone shows that modifications must be made to each in order for them to be consistent. The palaeomagnetic data resolve the geological problem of the situation of Tasmania in the Lachlan orogenic zone, while geological considerations show that a plate tectonic model is not a necessary explanation of the palaeomagnetic data and the rotations can be explained by internal deformation rather than block rotation.
