A study by Tulane University and international partners reveals that parts of Earth's crust in the East African Rift are stronger and more resistant to breaking apart than previously thought, due to dehydration from a heating event 80 million years ago, which removed water and CO2, making the plates more rigid and less prone to deformation.
Deep beneath East Africa, rhythmic mantle pulses are causing the continent to split, with multiple mantle plumes fueling volcanic activity and shaping the region's geological evolution, ultimately leading to the formation of a new ocean.
Scientists have discovered rhythmic pulses of molten mantle rock beneath Ethiopia's Afar Rift, which influence the stretching and cracking of Earth's crust, potentially leading to the formation of a new ocean basin, and revealing a dynamic connection between deep Earth processes and surface geological activity.
Scientists have discovered rhythmic pulses in Earth's mantle beneath Africa's Afar region, driven by molten magma, which influence tectonic plate movement, volcanic activity, and the formation of a new ocean basin, providing new insights into Earth's dynamic interior and surface interactions.
Scientists have discovered rhythmic pulses in the mantle beneath the Afar region in Africa, where tectonic plates are rifting apart, leading to the formation of a new ocean basin. These pulses, detected through chemical analysis of volcanic rocks, suggest that mantle upwelling is influenced by plate dynamics, providing new insights into Earth's surface and interior interactions.
A recent study published in the Journal of Geophysical Research: Solid Earth explores the formation of the East Coast of the United States during the breakup of the supercontinent Pangea. The study analyzes the structure of rocks and the presence of magma-derived rocks along the East Coast, shedding light on how the continent was pulled apart during Pangea's fragmentation. The research provides insights into the formation of passive margins, which are stable regions with minimal faulting or magmatism, and their vulnerability to geohazards such as earthquakes and erosion.
