Dr. Shelton’s recent and ongoing research addresses basic scientific questions regarding transport and deposition of metals in a wide variety of hydrothermal systems. In many cases, economic geologists perform detailed studies of individual ore deposits and extrapolate their results regionally, without ever looking at the large volumes of unmineralized rocks through which the ore fluids flowed. To provide a context within which to place studies of individual ore deposits/ore districts, Dr. Shelton and his students use geochemical and stable isotopic tools to
- define fluid source regions,
- identify fluid flow pathways,
- reconstruct fluid-rock reactions along pathways, and
- determine mechanisms of ore precipitation, with the goal of developing predictive models for ore deposit formation.
Dr. Shelton applies stable isotope geochemistry to a wide variety of problems, many of which involve sedimentology and diagenesis of Paleozoic carbonate rocks. Kevin’s interests are eclectic and over the years have ranged from studies of Cretaceous ammonoids to gold formation in Archean greenstone belts. With the recent arrivals of Jim Schiffbauer and John Huntley at MU, he has rekindled a decades-long fascination with the Upper Cambrian rocks of Missouri. Together they hope to understand the global and local contributions to carbon isotope signals preserved in these rocks in order to determine what effects the processes leading to C isotope variability had on biota.
