New research from Abati et al. regarding the Spanish Central System batholith reveals “the presence of discrete Andean-type plutons within the dominant post-collisional batholith.” The authors “propose that back-arc basin closure and the subduction of hyperextended segments of

New research suggests that huge asteroid impacts on early Earth might've actually benefited primitive life instead of hurt it! ☄️ Dr. Nadja Drabon of Harvard University brings early Earth to life with her research on giant impacts and the clues they leave behind in ancient

Ever wonder how we know what's going on below Earth's crust? 🌎 Brett Carpenter, representing GSA’s Continental Scientific Drilling Division, discusses how drilling deep into the Earth reveals the processes that shape continents, faults, and the subsurface environment. This

What controls rifted margin symmetry? New geodynamic models reveal that mechanical anisotropy alone can drive the transition from symmetric to asymmetric rifting—without needing changes in rheology. By simulating inherited fabric using a transversely isotropic visco-plastic

Ever wonder how we study Earth's ancient history? Mark Schmitz, leader within GSA’s Geochronology Division, explains how time itself is measured in the geological record. Using cutting-edge isotopic and analytical techniques, geochronologists are rewriting the timelines of

Ever wonder how GPS can pinpoint your location so accurately? In the latest episode of Geology Bites, MIT’s Tom Herring explains how high-precision geodesy—once costing tens of thousands of dollars—is becoming so affordable that your phone might soon know your position down to
