Many subsurface studies are focused on rocks below on Sedimentary Cover below a specific surface area where lateral
variation of Geothermal Temperature Field LaTeX Math Inline body --uriencoded--\%7B x, \, y \%7D
maybe insignificant comparing to variation along the true vertical direction LaTeX Math Inline body T_G(x, \, y, \, z)
