Paleo- to Mesoarchean polymetamorphism in the Barberton Granite-Greenstone Belt, South Africa: Constraints from U-Pb monazite and Lu-Hf garnet geochronology on the tectonic processes that shaped the belt: Discussion

Abstract

[Cutts et al. (2014)][1] combined thermodynamic modeling of compositional change in metamorphic garnet with metamorphic peak and retrograde pressure-temperature ( P - T ) data derived from quantitative P - T pseudosections to determine clockwise P - T paths for several samples from the Tjakastad
