Scientists Discover Hidden Mantle Layer Beneath the Himalayas Challenging Century-Old Theory

For decades, geologists believed the Himalayas were built on a double layer of continental crust. New research overturns that view, revealing that a dense slab of mantle rock actually wedges between India’s and Asia’s crusts beneath the range. This “mantle sandwich” better explains seismic data and how the mountains remain so stable while rising by about 1 cm each year.
