Large explosive eruptions occur in Yellowstone around once every 700,000 years, according to the U.S. Geological Survey.

As well as offering new insights into mantle composition, the drill core gives us other glimpses into Earth's deep geology and the conditions that could have been involved in the origins of life.

This is a 3D view of the top 1,000 kilometers of the earth's mantle beneath the central Pacific showing the relationship between seismically-slow "plumes" and channels imaged in the study.

The study of Structural Geology and Tectonics concerns the deformation of the Earth's crust and mantle. The scale of observation can be from the submicroscopic level to a mountain chain like the Rocky ...

By dragging huge chunks of crust into the mantle, Earth's middle layer ... But it shows the diversity of planetary geology that could lurk elsewhere in the cosmos. "In the end, understanding ...

We are also studying komatiites, the hottest lavas that ever erupted on the Earth's surface and what they tell us about the temperature of the Archaean mantle. The Origin of Granites - We have used ...

My research focuses on crystal structures and elastic properties of silicate and oxide minerals of the deep mantle. Initially, I did this by theoretical calculation and prediction of hydration sites, ...
