Dr David Haig has been retired for 20 years or so, but that hasn’t stopped him from making a huge voluntary contribution to Earth and Planetary Sciences in his role as Senior Honorary Research Fellow at UWA. He started his address by announcing that since this time last year, the Bowling Club room in which we meet has moved 7 centimetres to the north! Of course, the rest of the building and indeed our whole continent has done the same thing. In contrast to this Asia is moving in an easterly direction at the rate of 3 cm per annum and this is part of the reason why the Indian Ocean is slowly closing down. David outlined the changes that have taken place during the millions of years between the Jurassic period and now, and demonstrated that the Australian shoreline is constantly changing. David then drew our attention to Timor-Leste off the northern coast of WA, and gave us a very informative description of how the island was formed some 1.6 m years ago. He focussed on the Matebian mountain which runs from north to south and has two peaks – Feto and Mane – and explained how it was formed, including by moving plates and a huge collision. David and a handful of local colleagues in Timor found out that adjacent rocks came from two distinct eras, namely early Jurassic and deep-sea crustacean. The former fell like a large pebble into the latter and this resulted in Olistolith rock sediment – a chaotic mass of materials. A little closer to home, the Batavia micro-continent used to be very close to where Perth now is, but it is now about 1,600 kms west of our coastline. David concluded by reminding us that change is continual, but the human species does what it can to conserve health, wealth and its environment.
