Metamorphic and geochronological evolution in the Musgrave Ranges, Central Australia
Contrasting PTt paths obtained from high grade metamorphic rocks in Musgrave Ranges of Central Australia near Amata, indicate that Gneiss Terrane north of the Woodroffe Thrust and the granulites which outcrop south of the thrust represent two distinct crustal blocks whose tectonothermal histories only converged 1n the Middle Cambrian. The granulites record a complex, well preserved metamorphic history which is characterised by a sigmoidal PTt path consisting of an initial phase of near...[Show more]
