Fig. 4From: Geothermal energy from the Main Karoo Basin? New insights from borehole KWV-1 (Eastern Cape, South Africa)Stratigraphic log of the Ripon Formation intersected in borehole KWV-1 and trends of thermophysical properties on a reservoir scale. Intervals without measurements (dolerites) are grey shaded. Scale bars 100 m, Fm Formation. All lithologies are classified as impermeable. Fine-grained sandstones, the dominant lithology, show the highest thermal conductivity. Specific heat capacity reveals the highest values in siltstones and fine-grained sandstonesBack to article page
