Abstract

Small–scale isoclinal folds in Pre–Cambrian schists and quartzites near Frenchmans Cap, Tasmania, were formed during the Pre–Cambrian Frenchman Orogeny but the large open folds were produced during the Devonian Tabberabberan Orogeny. The Mary Antiform (Devonian) at the Raglan Range can be “unrolled” to leave the foliations almost horizontal, indicating that the isoclinal folds were recumbent prior to the Palaeozoic.
