Question
An existing oil shale extraction company wants to extract coal from the Windy Hill region after conducting 10
exploratory bore holes. It has been discovered that there is an association between the basement geology,
intrusions and the oil shale to produce high grade coking coal – anthracite - in the Windy Hill region.
In order to extract this oil shale and coal, a rough estimate of the volume of the deposits needs to be found below
the water table.
An initial application with the government environmental department for mining the resource areas have
enforced an exclusion on mining around the following:
• Within 1km of any overland water flow;
• Within aquifers that drain directly into the overland water flow at depth.
In order to progress the mining operation, the company is seeking to identify ground water flow based on the
geology map and the drilling data.
Question: 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.
