BMM-WHS

The Barberton Makhonjwa Mountain Land (BMML) contains the oldest well-preserved sequence of volcanic and sedimentary rocks on Earth. These highly accessible Archaean outcrops present a continuous 350 million year geological sequence, from 3 600 million years ago. The physical and chemical characteristics of these rocks are so remarkably well preserved that they provide a globally unparalleled history of the early Earth. In particular, they provide unique evidence of the formation of the earliest oceanic and continental crusts and of the initial phase of the evolution of our biosphere. The Barberton Makhonjwa Geotrail is the principal geoheritage product within the BMML
