Proterozoic-Cambrian detrital zircon and monazite ages from the Anakie Inlier, central Queensland: Grenville and Pacific-Gondwana signatures

Fergusson, Christopher Lloyd; Carr, Paul Francis; Fanning, Christopher; Green, Tracey

Description

The Anakie Metamorphic Group is a complexly deformed, dominantly metasedimentary succession in central Queensland. Metamorphic cooling is constrained to ca 500 Ma by previously published K-Ar ages. Detrital-zircon SHRIMP U-Pb ages from three samples of greenschist facies quartz-rich psammites (Bathampton Metamorphics), west of Clermont, are predominantly in the age range 1300-1000 Ma (65-75%). They show that a Grenville-aged orogenic belt must have existed in northeastern Australia, which is...[Show more]
