Heat flow in the Basin and Range province and thermal effects of tectonic extension
A.H. Lachenbruch
1978, Pure and Applied Geophysics PAGEOPH (117) 34-50
In regions of tectonic extension, vertical convective transport of heat in the lithosphere is inevitable. The resulting departure of lithosphere temperature and thickness from conduction-model estimates depends upon the mechanical mode of extension and upon how rapidly extension is (and has been) taking place. Present knowledge of these processes is...
