Professor Marian Holness: Under the volcano

The composition of magma erupted from volcanoes is controlled in part by crystallisation if it has been temporarily stalled in the crust before eruption, commonly giving rise to more explosive eruptions. The behaviour of stalled magma can be inferred from examination of solidified rock now exposed at the surface by erosion. In this talk Prof Holness will give a guided tour of one such body – the 55 million year old Skaergaard Intrusion of East Greenland.
