Brown's comment on Cutts et al. (2014) weighs in on this central controversy around the likely geodynamic environments that prevailed in the Archean Earth, and he focuses on the Barberton granite-greenstone belt as one of the type localities of Archean crustal processes in the world. In the Barberton granite-greenstone belt, 3.55–3.45 Ga trondhjemite gneisses and associated high-pressure amphibolite-facies metamafic and metasedimentary rocks are structurally juxtaposed against lower-greenschist-facies rocks of the Onverwacht Group (...
