Another paper on modelling of subsurface water. Again, Elsevier wants you to pay for it, and the pdf is too large to post here (1.5 MB).
QUOTE The thickness of the liquid subsurface layer depends primarily on the crustal heat flux, the thermal conductivity of the overburden sediments, and the surface temperature. A subsurface liquid water layer of 1 to 2 km can be achieved under present day surface temperature conditions and a crustal heat flux of 15–30 mW m− 2 With some simplifications (steady state, no hydrostatic pressure... ) one can calculate temperature and pressure at a given depth as follows. Density and thermal conductivity for some materials is here. Then look up p and T in the phase diagram of your favourite substance |
