This thesis is a compilation of data and research on the geology, mining, and manufacturing of critical minerals and how they are contributing to the energy transition. This research follows the elements from their respective deposits, refinement facilities, and the final product production through the supply chain. The geology and formation of the minerals is prioritized to have a better understanding of the physical and chemical properties that these minerals possess and why they are considered critical. The history of energy production is included in the research to better emphasize the importance of critical minerals and to better predict how they may contribute in the future. Along with compiling data on the various steps of the life cycle of a mineral, the reserves and future resources are also taken into consideration. All gathered data is formatted into a field guide for easier accessibility.
