Global UHP metamorphism and continental subduction/collision: the Himalayan model
Continental crust (density~ 2.8 g· cm-3) resists subduction into the earth's mantle (~ 3.3 g·
cm-3) because of buoyancy. However, more than 20 recognized ultrahigh-pressure (UHP) …

Crustal structure: A key constraint on the mechanism of ultra-high-pressure rock exhumation
The distribution of ultra-high-pressure (UHP) metamorphic rocks demonstrates that burial
(to> 100 km) and rapid exhumation (> 1 cm a− 1) of continental crust is a normal part of early …
