Bathymetry of the ultraslow Southwest Indian Ridge at 9-16°E. Magma is focused to narrow seamounts like Joseph Mayes Seamount in the foreground.
Undergraduate student Dusty Aeiker takes a photo of the Loomurwak tuff ring, with Oldoinyo Lengai (the world's only active carbonatite volcano) in the background. Both the tuff ring and the sratovolcano are manifestations of the magmatism in the East African Rift. The Loomurwak tuff ring carries fragments of the deep mantle beneath this region.
The tectonics faculty and students work in numerous locations around the world (and on other planets!) and also undertake physical and computational experiments to better understand the development of the lithosphere. Here are some of our current projects.

Melt retention by strong grain boundary tension. A pulse of buoyant magma ascending through a viscous matrix with high grain boundary tension (left) loses melt to the matrix during ascent. In the absence of strong tension on grain boundaries (right) the pulse travels as an undisturbed solitary wave.
