Conceptual 2-D models (uppermost 10 km) a of a magmatic and metamorphic crust (vertical exaggeration approx. fourfold) and b of a sedimentary crust (vertical exaggeration approx. threefold). The model rock units (bold capital letters) and the corresponding thermal conductivity under ambient conditions (in italics, given in W m−1K−1) are denoted (see Table 2)
