Perturbation of Homogeneous Thermal Conductivity Distribution in Some Carbonates by Stylolites

Stylolites are partings within rocks that exhibit complex mutual column and socket interdigitization. These features can exhibit<br>pronounced roughness on several scales. Stylolites, under deep-burial conditions, could permit circulation of undersaturated<br>fluids and become reservoirs allowing also deep commercial gas production. However, the impact of stylolites on variations in<br>thermal conductivity in carbonates is not well-known. This study was undertaken to investigate the heterogeneity in thermal<br>conductivity in a variety of carbonate specimens containing different types of stylolites.
