Scott Miller

Ph.D. Candidate

My research spans the Archean and Proterozoic Eons to answer broad scale questions about the geophysical and geochemical evolution of Earth's continents. It focuses on the Precambrian paleomagnetism, geochronology, and geochemistry of Indian Cratons (Dharwar, Singhbhum, Bundelkhand Cratons). My paleomagnetic and geochronological investigations of Archean-Proterozoic mafic dykes constrain the paleogeographic locations of the Cratons, provide insight on the timing and location of supercontinent formation and breakup, and characterize the Earth's magnetic field in deep time. My geochronological-geochemical work involves studies on several key lithologies present in ancient cratons, including mafic dykes, granitoids, and banded iron formations (BIFs). Major/trace element compositions and Lu-Hf, Sm-Nd, and Pb-Pb isotopic analyses from these rocks help us learn more about ancient crust-mantle dynamics that were crucial in forming Earth's continents and modern style horizontal plate tectonics. It is truly exciting to work on billion-year timescales, with global datasets, and with international collaborators!

I also have an interest in geoethics and geoequity, and want to make it just as much a part of my career as paleomagnetic and geochemical research. I moderate the GeoActivists group at UF and enjoy visiting Florida's springs in my free time!
