Malolotja Geology

The geology of Malolotja is very diverse and includes some granites (Lochiel Granite, estimated to be about 3 000 million years old), but is predominantly made up of metamorphosed sedimentary rock formations of the Barberton Mountains, including the Onverwacht, Fig Tree and Moodies series of rocks. These rocks are thought to be about 3500 million years old, and are thought to contain fossils of the earth's oldest life forms - blue-green algae. It is in these mountains that the ironstones, talc schists and other metal bearing rocks are found, where the various mining activities have been carried out over the last hundred years.
