Joseph Armstrong

Dr. Joseph Armstrong is a Lecturer and geological researcher at the School of Geosciences, University of Aberdeen. He specializes in critical mineral deposits for the Energy Transition and serves as Programme Director for the Sustainable Energy Geoscience (SEG) MSc. His interdisciplinary research spans geochemistry, fieldwork, and collaboration across disciplines like environmental science and engineering.

Research interests include inorganic geochemistry techniques (e.g., ICP-MS, SEM, Raman spectroscopy), Paleoproterozoic to Neoproterozoic sedimentary systems, and the geochemical evolution of early terrestrial ecosystems. Key areas of focus are carbon and rare earth element cycling, fluid-rock interactions, and mineralization processes in hydrothermal systems.

Recent publications analyze Scottish geological formations (e.g., The Aird marbles, Bowland Shale), Paleoproterozoic sulfur isotope records, and lithium concentration in Caledonian magmatic systems. His work contributes to understanding mineral resource potential and environmental impacts of shale exploration.

Awarded Fellow of the Geological Society (FGS), Armstrong is active in academic collaborations and field teaching. His research integrates field data with laboratory analyses, addressing both fundamental geological questions and applied energy transition challenges.
