Thermal conductivity of several kinds of igneous rocks containing Granite, Diorite, Gabbro, Liparite, Andesite and Basalt, 45 in all, are measured by the divided-bar method at various temperatures from 140°C upto 280°C. Measured values vary for different kinds of rocks ranging 3_??_6×10-3cal/cm. sec. and for rocks of the same kind, the conductivity seems proportional to their bulk density. Temperature coefficient of thermal conductivity is positive except for Granite and Liparite.
