SHRIMP U-Pb monazite dating of 1600-1580 Ma amphibolite facies metamorphism in the southeastern Mt Isa Block, Australia

Giles, D; Nutman, Allen

Description

SHRIMP U-Pb monazite dates of ca 1600-1580 Ma are reported from three samples taken from the southeastern margin of the Proterozoic Mt Isa Block. The samples include an upper amphibolite facies paragneiss and a pegmatite from the host sequence of the Cannington Ag-Pb-Zn deposit and a middle amphibolite facies metasediment from the Soldiers Cap Group near Maronan station. These dates are interpreted to represent the timing of amphibolite facies metamorphism at the southeastern margin of the Mt...[Show more]
