Temperature and bulk composition control on the growth of monazite and zircon during low-pressure anatexis (Mount Stafford, Central Australia)
The formation, age and trace element composition of zircon and monazite were investigated across the prograde, low-pressure metamorphic sequence at Mount Stafford (central Australia). Three pairs of inter-layered metapelites and metapsammites were sampled in migmatites from amphibolite-facies (T ∼600° C) to granulite-facies conditions (T ∼800° C). Sensitive high-resolution ion microprobe U-Pb dating on metamorphic zircon rims and on monazite indicates that granulite-facies metamorphism occurred...[Show more]
