The influence of erosion upon the mineral facies of rocks from different metamorphic environments

Abstract:

Metamorphism of tectonically thickened continental crust or subducted sediment wedges is likely to take place in a thermal regime where temperature increases by conductive relaxation whilst concurrently pressure decreases by erosion of the pile. The mineral facies of rocks reaching the surface do not reflect any one geotherm through the pile but lie on a locus of P-T conditions, the metamorphic geotherm, which will generally be concave towards the temperature axis. Maximum pressures on the me...
