Palaeoproterozoic evolution of the Challenger Au deposit, South Australia, from monazite geochronology

McFarlane, Christopher

Description

Monazite in granulite facies metatexite migmatites (Christie Gneiss) hosting the Challenger Au deposit, South Australia, records a series of growth and resorption stages over a c. 60 Myr period between 2470 and 2410 Ma. A combination of electron microprobe X-ray mapping and in situ ion-microprobe dating was used to delineate and date five compositional domains. The oldest prograde metamorphic components are preserved in granoblastic gneisses surrounding the deposit, and as small high-Y cores in...[Show more]
