We made 980 thermal conductivity measurements on igneous, metamorphic, sedimentary, and volcanic rock samples from Korea. The average thermal conductivity of igneous, metamorphic, sedimentary, and volcanic rocks are 3.41 W/m-K, 3.98 W/m-K, 4.10 W/m-K, and 3.21 W/m-K, respectively. Thermal conductivity values of a rock type generally have a wide range because thermal conductivity depends on various factors such as dominant mineral phase, micro-structure, anisotoropy and so on. Thermal properties (thermal conductivity, thermal diffusivity and specific heat) are important variables which are used to design a geothermal heat pump(GHP) system. Therefore, our thermal property data can contribute on a efficient design of a GHP system.
