Devonian-Carboniferous granites are widespread in Tasmania. In the east they intrude the Ordovician-Early Devonian quartzwacke turbidites of the Mathinna Supergroup, whereas the western Tasmanian granites intrude a more diverse terrane of predominantly shelf sequences, with depositional ages extending probably back to the Late Mesoproterozoic. The earliest (~400 Ma) I-type granodiorites in the east may be arc-related and pre-date the Tabberabberan Orogeny (~388 Ma), which appears to represent the juxtaposition of the two terranes. Subsequently more felsic and finally strongly fractionated I- and S-type granites were emplaced until ~373 Ma. In western Tasmania, mostly felsic and fractionated I- and S-types granites were emplaced from ~374-351 Ma, possibly in response to back-arc or post-collisional crustal extension
