The geologist's view: It could be a gold mine, but not for a long time

Afghanistan has some of the most complex and varied geology in the world. Mining companies have always known about its potential because geologically it lies in a very interesting region. And it has an undeveloped mining industry in comparison with its neighbours. It has incredibly old rocks, some of which are Archean in age (more than 2,500 million years old), and then those are overlain by rocks that are from eras right up to the present day.

The natural world: The impact of a dramatic setting in Arizona

In front of me is one of the best preserved impact craters in the world, a giant hole in the sedimentary rocks of the Colorado Plateau, near Flagstaff in Northern Arizona. About 50,000 years ago you would have been in serious trouble if you were standing where I am today; a large iron meteorite, weighing in at perhaps 500,000 tonnes slammed into the Earth's surface at speeds in excess of 11km/s. The most recent studies indicate that this colossal impact released 10-11 megatonnes of energy – over 500 times more than the atomic bomb that exploded over Nagasaki in 1945.
