The rates at which fault zones “heal” through secondary mineralization have been elusive, but uranium-thorium dating of calcite growth in fault-zone fractures may provide the answer.
As the geologist’s beloved guidebook gets a digital makeover, his personal contributions to the field shed light on who he was as a scientist.
Fifty years after the birth of modern plate tectonics theory, a group of researchers highlights three key examples of how our planet’s shape-shifting outer layer has altered our climate.
Living in Geologic Time: Rafting through the past, present, and future of the Colorado River and the Grand Canyon.
Many tools of chemical analysis, experimentation, modeling, and theory have the potential to increase our understanding of how fracture patterns develop at different geological time scales.
New tools to model and visualize subduction zones in 3-D are providing researchers with insights into the gaps inherent in the theory of plate tectonics.
Third Pod from the Sun talks with pioneering geophysicist Xavier Le Pichon about what it was like to be a young scientist challenging deeply held theories.
Numerical simulations of earthquake cycle deformation reveal that co-seismic and interseismic fault propagation can produce distinct propagation angles that may be recorded in the crust.
In October, we celebrate AGU’s Centennial by looking under our feet, where the relatively new study of plate tectonics is evolving rapidly.
Though coastal plutons spew greenhouse gases into the atmosphere as they form, they also pull some of those gases back out of the atmosphere as they break down over time.
