Fig 1-5. Heat flow plotted as a function of the radiogenic heat production of surface rocks. (Philpotts, 1990) Fig 1-7. Possible temperature distributions in a stable lithosphere (far removed from spreading or convergent plate boundaries). Two oceanic (O1 & O2) and two continental (C1 & C2) geotherms are shown to cover the range of possible values. Also included are stability fields of the Al2SiO5 polymorphs and various beginning of melting curves. (Philpotts, 1990) Fig 3-1. From Philpotts (1990) Fig 3-2. From Philpotts (1990)
