How hot is the mantle under the continents?

Does extension drive melting, or upwelling drive melting and extension?

How do we interpret seismic tomography images in terms of temperature, melt and water?

Professor Terry Plank takes seismic tomography in a new direction, and with a joint inversion with petrology, solves directly for the geotherm beneath the Basin and Range of the Western US. We find evidence for large regional mantle temperature variations, and extension where mantle is hottest and seismically slowest.

Professor Terry Plank is the Geological Society of America James B. Thompson Distinguished International Lecturer. Professor Plank is a world expert on magmatic systems and processes and her significant and lasting contributions to the field of Earth Sciences have been well recognised.

Professor Plank is a Fellow of the American Geophysical Union, The Geochemical Society, the Geological Society of America, and the Mineralogical Society of America and since 2013 a member of the National Academy of Sciences.

Don't miss Professor Plank's first talk on Thursday 27 July called "Volatiles and Volcanic Vigour”.

Book individual or group discussion time with Professor Plank.

Please contact Manuela Tost to schedule time with Professor Plank on Friday 28 July.
