- The system is a uniform overburden of thickness h, thermal The system considered k1, and diffusivity α1 overlying a semi‐infinite substratum (conductivity K2, diffusivity α2). It is shown that if the temperature of the surface varies with time t as T0 sin ωt, the temperatures v1, v2 in the overburden and the substratum respectively are given by: (Formula Presented.) The apparently simple boundary value problem has thus a surprisingly involved solution. The solution is of considerable importance in shallow geothermal measurements in, for example, moraine‐covered areas such as the Swedish Precambrian or in areas of uniform in situ weathering.
