Description

Devonian-Carboniferous granites are widespread in Tasmania. In eastern Tasmania, Devonian granites intrude Ordovician-Early Devonian quartz-rich turbidites of the Mathinna Supergroup. The earliest (~400 Ma) I-type granodiorites may be arc-related. Following the Tabberabberan Orogeny (~389 Ma), more felsic and, finally, strongly fractionated I- and S-type granites were emplaced until ~373 Ma. In contrast, western Tasmania granites intrude a more diverse terrane of predominantly marine shelf...[Show more]
