This study looked to analyze temperature effects on thermal transport properties of dry granite, gabbro, marble, and sandstone samples. An instrument was used with a high temperature chamber to perform thermal conductivity measurements on the rock samples. The thermal conductivity of the granite, marble, and sandstone samples were found to decrease with increasing ambient temperature, while the gabbro remained almost constant....
In deep sedimentary basins, geothermal processes are significantly affected by heat transport properties. In this study, thermal properties of deep sediment core samples were measured using a thermal constant analyzer with transient plane source method. Results showed that thermal conductivity of the sediment near the seafloor was low and increased with depth. Thermal conductivity of coal was lowest of all samples, while cemented rock exhibited the highest thermal conductivity....
An investigation was undertaken to try to gain insight into altered thermal properties of the seafloor near Japan caused by the earthquake and subsequent tsunami that devastated Japan and caused the meltdown of the nuclear reactor in Fukushima in 2011. Core samples of rock were drilled by the JFAST project and these samples were analyzed using the transient plane source (TPS) technique to determine thermal conductivity, thermal diffusivity and volumetric heat ...
