Lithosphere strength
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 … Web18 aug. 2013 · In the case of young lithosphere, the low ductile strength is consistent with the low bulk differential stress <300 MPa measured in the middle crust, as in Taiwan 24. This view reflects the...
