Why is it important to know when and how plate tectonics began, and what was Earth’s tectonic style before plate tectonics?

By Lindy Elkins-Tanton, Director of the School of Earth and Space Exploration at Arizona State University This the fourth of four blogs written in advance of a meeting at the ETH conference facility in Ascona, Switzerland, to discuss four related questions about the evolution of the solid Earth: “When did Plate Tectonics Begin on Earth?”;… Read More Why is it important to know when and how plate tectonics began, and what was Earth’s tectonic style before plate tectonics?

NEW Animation of Subduction Zone Processes Developed for the Undergraduate and 2YC Audience

by Bob Stern, University of Texas at Dallas Animations are great ways to show Earth processes to students, but the quality of such animations is spotty at best (quality here refers to both the soundness of the science as well as the aesthetic quality of the animation itself). I am a university professor and I… Read More NEW Animation of Subduction Zone Processes Developed for the Undergraduate and 2YC Audience

Structural Geology and Tectonics Research for Development in Africa

by Mark Jessell 1 Introduction After a number of years working in this area, this essay summarises my thoughts on the use of research in Structural Geology and Tectonics (SGT) as a development tool, and provide links and references to projects and organisations active in this area. To be clear “development” in this case refers… Read More Structural Geology and Tectonics Research for Development in Africa
