Lithosphere ending depth
Web25 apr. 2024 · The density of the lithosphere varies depending on temperature, depth and age. At about 50 kilometers (30 miles) below the Earth's surface, density measurements reach 200,000 pounds per square inch (13,790 bars). Due to the pressure from the above crust and mantle, lithospheric density generally increases as both age of the surrounding … Web4 aug. 2024 · Deformation microstructures of peak metamorphic conditions in ultrahigh-pressure (UHP) metamorphic rocks constrain the rheological behavior of deeply subducted crustal material within a subduction channel. However, studies of such rocks are limited by the overprinting effects of retrograde metamorphism during exhumation. Here, we …
