Fewer then 200 impact craters are currently known on Earth but others must lie hidden beneath younger rocks. At Meteor Crater, in Arizona, the classic example of an impact crater, Mike will explain how careful detective work over many decades led to the realisation, firstly, that all is not what it seems, and ultimately gave rise to an understanding of some of the Meteor Crater enigmas.
Closer to home, Mike will describe how a chance discovery made on holiday led to the discovery (maybe) of the only impact crater known in the UK, represented by a gravity anomaly beneath the Scottish Highlands. However, reanalysis of the gravity data suggests that the crater was much larger than originally thought, indeed too big to fit in the space available. Can this problem be resolved?
Mike is an acknowledged expert on meteorites and impacts, so this promises to be a really fascinating lecture - not to be missed!
