Mineral-scale trace element and U-Th-Pb Age Constraints on Metamorphism and Melting during the Petermann Orogeny (Central Australia)
High-pressure amphibolite-facies migmatitic orthogneisses from the Cockburn Shear Zone (CSZ), northern Musgrave Block in central Australia, were formed during the 580-520 Ma intraplate Petermann Orogeny. The shear-zone hosted orthogneisses are of an intermediate bulk composition that promoted the growth of rare earth element (REE)-bearing major phases (garne and hornblende), as well as numerous accessory phases (zircon, titanite, apatite, epidote and allanite), all of which are potential...[Show more]
