Continental reworking during overprinting orogenic events, Southern Prince Charles Mountains, East Antarctica
In situ electron microprobe monazite dating and mineral equilibria modelling of amphibolite—granulite-facies metapelites from the southern Prince Charles Mountains, East Antarctica has been carried out to unravel the P—T conditions, spatial extent and structural style of two overprinting orogenic re...

In situ electron microprobe monazite dating and mineral equilibria modelling of amphibolite—granulite-facies metapelites from the southern Prince Charles Mountains, East Antarctica has been carried out to unravel the P—T conditions, spatial extent and structural style of two overprinting orogenic records.
