flag Scientists discover two large, ancient "islands" in Earth's mantle, challenging views on geological processes.

flag A new study from Utrecht University, published in Nature, has found two large, ancient "islands" in Earth's mantle that are much hotter and more rigid than surrounding areas. flag These "Large Low Seismic Velocity Provinces" (LLSVPs) challenge the idea of a well-mixed and fast-flowing mantle, suggesting it may be less active than previously thought. flag The discovery could change our understanding of geological processes like volcanism and mountain formation.
