L ittle is known about the nature and evolution of Earth's continental crust before a few billion years ago because cratons, or stable swaths of the lithosphere more than 2–3 billion years old ...

and the geologist who ten years ago was embarrassed by the shortness of the time allowed to him for the evolution of the earth's crust is now still more embarrassed by the superabundance with ...

enormous glaciers flowed across the Earth's surface in powerful frozen rivers like "giant ice bulldozers" that pulverized our planet's crust and may have contributed to the evolution of complex ...

At CU Boulder, we use petrology to study the formation of volcanoes and their magmatic sources, the evolution of continental crust during the growth and destruction of mountain belts, the genesis of ...

We have expended a deal of effort in understanding the growth of the continental crust on Earth, notably from the in situ measurement of isotopes in single mineral grains, and as a consequence the ...

the origin and evolution of the Earth's mantle and continental crust; the generation and transport of basaltic magma; the development and evolution of volcanic systems; magma degassing; volcanic ...

What magma evolution processes generate continental crust, and over what timescales? And, how are mid-ocean ridge magmas and eruptions affected by sea level changes? I investigate these questions and ...

Continental and oceanic plates all fit together to form the outer crust of the planet. Eight major plates are named on the diagram below. Heat from the core makes magma in the mantle rise towards ...

These movements have altered the positions and topography of the continents, contributing to the current state of the planet’s crust. While certain regions of the continental crust, known as ...

Our research group uses multidisciplinary tools to address fundamental geological questions related to the origin and evolution of Earth and other planetary bodies. The main focus is on the crust ...
