Part 7/11:
One of the most groundbreaking discoveries surrounding Mount Paektu is the identification of a large reservoir of molten rock and hydrated material, referred to as the "Big Mantle Wedge" (BMW). Seismic studies have revealed its unique mechanics—this molten reservoir is not connected to conventional subduction paths but instead arises from stagnant slabs of oceanic crust, providing a critical engine for volcanic activity, contrary to established tectonic paradigms.
