Appendix 1: Outcrop Rock Units & Geotechnical Summary Rock Type Red Sandstone Volcanic Group Massive Limestone Shale Porphyrite Description Poorly sorted clast supported quartz sandstone with a range of rounded to angular lithic fragments contained within the matrix. Andesite tuffs and flows formed in a phreatic environment. Rhyolite tuffs formed in a phreatic environment associated with plagioclase phenocrysts. Massive basaltic pillow lavas flows associated with chlorite alteration and intensely weathered at surface. Limestone containing calcite crystals in void space. Inter-bedded impermeable shale containing occasional calcite crystals derived from fossiliferous material. Phenocrysts of 17% Orthoclase, 33% Quartz, 30% Plagioclase, 10% Hornblende, 5% Biotite, 5% Muscovite, tr. Sulphides Poorly sorted quartz-lithic conglomerate with some metamorphic fragments of various natures contained within the Conglomerate matrix and clasts of shale, sandstone and limestone.

Task C) Basement Geology Map
It has been found that there is a higher heat transfer to the oil shale from the sediments that are directly under the
gneiss thus allowing maturation of the shale to allow extraction of the oil.
Construct a basement geological map that shows the underlying regional metamorphic geology of the entire
region. Use the drilling logs in Appendix 2 to help identify areas of oil shale thus constraining the size of the
geological resource associated with Task D.
Along with the geological base map prior to the deposition of the sediments, the following is required:
• Infer the geological boundaries, including fault zones and folding for the region.
• Identify the igneous rock types listed within the Porphyrite and Volcanic Group drilling (Appendix 2)
according to the International Union of Geological Sciences use of the Streckeisen international
classification system and provide an image of the rock that you have identified.
• Compare geophysical techniques that could be used to confirm the volume of the oil shale/ coal
resources and where there could be potential igneous intrusions.
