.... Amphibolites were derived from the metamorphism of tholeiitic basalts characterized by geochemical signatures similar to those of volcanic rocks of the nearby Pongola Supergroup. Quartzites are compositionally similar to sandstones from the Mozaan Group. LA-ICP-MS U-Pb analysis of zircon grains from grey...
