Situated in north-eastern South Africa, the Barberton Makhonjwa Mountains comprises 40% of the Barberton Greenstone Belt, one of the world‘s oldest geological structures. The property represents the best-preserved succession of volcanic and sedimentary rock dating back 3.6 to 3.25 billion years and forms a diverse repository of information on surface conditions, meteorite impacts, volcanism, continent-building processes and the environment of early life.
