Web14 aug. 2009 · The thermal conductivities of the main minerals of granite are in the range of 1.6 to 7.7 W/mK at room temperature ( Horai, 1971 ), which are much larger than that of air which is 0.03 W/mK at room temperature. Therefore an increase of the porosity results in a decrease in the thermal conductivity. http://www.aqtesolv.com/aquifer-tests/aquifer_properties.htm
