Drilling 2008

Summer 2008, CGB researchers travelled to the Barberton Mountain Land in South Africa to carry out scientific drilling in some of the oldest rocks on Earth. Working with colleagues from the Africa Earth Observatory Network, University of Cape Town they drilled into rock that is c. 3.4-3.5 billion years old to investigate early life and environments on ancient earth.

Professor Harald Furnes from Bergen and colleagues have discovered some of the world's oldest microbial fossils in these rocks, as reported in Science Magazine in 2004. In the 2008 field season researchers hoped to obtain a more complete understanding of these ancient fossils by collecting pristine drill core from the same rocks. They worked with scientists from AEON (Africa Earth Observatory Network) at the University of Cape Town and an experienced drilling team from DiT (drillers in training).
