The 18th in a series of annual conferences on the petroleum geology of Africa was held at the London Olympia, October 1-2. The series, organised by the Petroleum Exploration Society of Great Britain (PESGB) and the Geological Society of Houston, alternates between these two cities. The Olympia meeting was attended by over 500 delegates who followed two days of presentations, posters and an industry exhibition. Colin Reeves presented his most recent work on a plate-tectonic model for the dispersion of the other Gondwana continents from around Africa. A new discovery is the plate-tectonic role of a coast-to-coast Mwembishi shear zone stretching 3200 km from Namibia to Tanzania, passing through parts of seven African countries. It was active as a dextral strike-slip feature in Early Cretaceous time (135-129 Ma).
