METAMORPHIC PRESSURE ESTIMATES AND SEDIMENT VOLUMES FOR THE ALPINE OROGENY - AN INDEPENDENT CONTROL ON GEOBAROMETERS

Theories which regard the deep erosion (20-30 km) of orogenic belts as an important factor in the thermal development of the continents rely on pressure estimates from metamorphic geobarometers to give an estimate of the depth scale for this process. The imprecision of geobarometers, and the apparen...
