Extinct Style of Plate Tectonics Explains Early Earth’s Flat Mountains
The geologic record suggests that despite Earth’s hot, thin crust during the Proterozoic, mountains were still able to form thanks to an extinct style of crustal deformation.
A Novel Thermobarometer to Infer Mantle Melting Conditions
The algorithm RevPET automatically reverses the complex multi-phase fractional crystallization path of oceanic basalts and offers new perspectives for advancing mantle thermobarometry.
Himalayan Tectonics in the Driver’s Seat, Not Climate?
Earth’s oscillating climate is a natural guess to explain cyclic patterns in erosion, but new sediment data suggests that cyclicity may emerge from tectonic processes adding material to the Himalaya.
Subduction Zone Earthquakes: Fast and Slow, Weak and Strong
What causes slow earthquakes in subduction zones? New insights from numerical models suggest that a mixture of strong and weak rocks might be the cause.
Earth’s Continents Share an Ancient Crustal Ancestor
How did today’s continents come to be? Geological sleuths found clues in grains of sand.
Swipe Left on the “Big One”: Better Dates for Cascadia Quakes
Improving our understanding of hazards posed by future large earthquakes on the Cascadia Subduction Zone requires advancements in the methods and sampling used to date and characterize past events.
Lava from Bali Volcanoes Offers Window into Earth’s Mantle
Lava from the Agung and Batur volcanoes provides a near-pristine picture of Earth’s mantle and raises questions about all volcanoes along the Indonesian Sunda Arc and beyond.
Volcano—Tectonic Interactions at Etna
Mapping of a 2018 earthquake that ruptured the eastern flank of Mount Etna shows that it occurred on a tectonic lineament that predates the volcano, and the kinematics match nearby tectonic domains.
