Lecture by Matt Kohn (Boise
Lecture by Matt Kohn (Boise State University) given at the Geological Society on 20 February 2013.
As well as raising Earth's highest mountain range, the Himalaya, the collision between India and Asia has caused lively debate between geologists about how continental crust behaves during plate collisions. Matt Kohn will look at the various models for how the middle of the crust deforms. Does it 'ooze' like toothpaste, develop wedges like a snow plough, or become flattened like the collapse of a weakened pile? Each model carries with it its own implications for reconstructing how the Himalaya and the Tibetan plateau were formed.
