Extended Data Fig. 1: Geological map of the southern Barberton Greenstone Belt.
From: Earth’s earliest granitoids are crystal-rich magma reservoirs tapped by silicic eruptions
Modified from published maps21,26,27 based on our own field observations and interpretations, for example the presence of diorite enclaves in the Theespruit pluton and the fact that the Doornhoek pluton is largely granitic in character. The inset shows the location of outcropping Archean crust and the study area (red frame) on a map of South Africa.
