An existing mining company wants to a build a dam for their processing facilities and is seeking a suitable site that will ensure a permanent water supply of about 10000 ML. Their choice of locations is limited to roughly a 28km x 19km region, the visible area of the regional Geology Map. A) Regional Geology Task: You are required to establish a geological column and determine the geology history of the region in order to help identify 3 potential dam sites to ensure a permanent water supply (Regional Geology Map; Topographic Map; Appendix 1). Therefore, a brief summary (2 pages) of the geological history of the region should be discussed, including a note on the tectonic setting. The brief summary includes a geological column that has the oldest unit at the base and the youngest at the top. It may be helpful to also identify structural features, such as the thrust fault on the western side, within this column. Factors that should be identified within the geological history include aspects such as unconformities, igneous events, deformational events and metamorphic grade. Faults should be identified along with the movement along these faults. The plate tectonic settings need to be identified, where possible, and placed within the geological history. Evidence needs to be included regarding the principle of superposition for the geological history and appendices may be used.
