Geological structures exposed - for iPod/iPhone

By The Open University

What's Geological structures exposed - for iPod/iPhone about?

Understanding mountain building involves unraveling how and why rocks deform. Geologists Nigel Harris and John Whalley tour the Scottish segment of the Caledonian orogenic Belt to untangle the kinematics and the chronology of deformation. This material forms part of The Open University course S339, Understanding the continents.
