Energy dissipation from metamorphism http://sciencealtavista.wordpress.com/2010/02/
http://www.classroomatsea.net/general_science/plate_tectonics/cont-oc_destructive.htmlhttp://www.classroomatsea.net/general_science/plate_tectonics/cont-oc_destructive.html Results 1.3 * 10^11 Watts (every trench has sediment) 6.4 * 10^10 Watts (1/2 trenches have sediment) 3.2 * 10^10 Watts (1/4 trenches have sediment) (Plank & Langmuir, 1993; Holland & Powell, 1990)
Final Number Total Metamorphic Power ~ 2 * 10^11 Watts Subduction zones and Collisional Orogens are comparable in power. Equilibrium calculation and real metamorphic process: scenes from a troubled relationship Dave Waters - Metamorphic Studies Group Research in Progress 2010 (keynote); My daughter Helen drew this cartoon to illustrate the principle of the title. Equilibrium, on the left, believes metamorphic products should always follow ordered patterns governed by the logo on his t-shirt. He looks disgruntled because Process, on the right, is busy explaining why she won't do this metamorphism thing exactly the way he plans it. She clearly has her own style, and while her successful products may sometimes take unexpected forms, you can bet that she has found efficient ways of making them, because she wouldn't tackle any job that involved too much effort to get it started. http://www.earth.ox.ac.uk/~davewa/research/kinetics/process.html
