Overview
Dr. Kendall is a geochemist who uses the elemental concentrations and isotope compositions of geological materials to:
• Develop and use novel isotopic techniques to reconstruct the history of atmosphere and ocean oxygenation through time and its cause and effect relationships with biological evolution, seawater chemistry, biogeochemical cycles, and natural resource deposits
• Develop innovative geochemical methods that can serve as process tracers for energy and mineral resources, thereby improving genetic models of resource formation as well as exploration strategies for these important resources
Specific research themes:
• Development and application of the molybdenum, uranium, thallium, rhenium, and osmium isotope systems and redox-sensitive metal concentrations as tracers for local and global ocean redox conditions, and oxidative continental weathering and seafloor hydrothermal fluxes of metals (including bioessential metals) to the Precambrian and early Phanerozoic oceans
• Reconstruction of sedimentary environments using inorganic geochemistry (trace element concentrations and metal isotope compositions) of conventional and unconventional petroleum source rocks, and inferring the economic and environmental implications for energy resources
• Elemental geochemistry, metal isotope geochemistry, and geochronology of ore deposits and the implications for ore formation and exploration
