Thallium Isotope Implications for the Metalliferous Source of Carlin-type Deposits in northern Nevada
… of Au. This study describes the first-ever Tl isotope data collected for ore- and late-stage mineralization from a Carlin-type system, as well as for a suite of potential source rocks, with the goal of fingerprinting Au sources for these systems in northern Nevada. Although not pointing to an …

A multiproxy investigation of oceanic redox conditions during the Cambrian SPICE event
… as the SPICE event (Steptoean Positive Carbon Isotope Excursion). Previous studies have revealed the SPICE caused large changes to the global cycles of carbon, sulfur, uranium, molybdenum and the overall trace metal content of seawater. Furthermore, the initiation of these changes appears to …

Unraveling Paleoenvironmental Stress in the Late Devonian and Mississippian: Insights into Redox Dynamics and Photosynthetic Adaptations Elucidated Through Geochemical Proxies
… on the findings of Chapter 1 and applies the thallium isotope redox proxy to track marine deoxygenation on the global scale. Specifically, this proxy is dependent on the global distribution and deposition of Mn oxides and therefore can provide further insight into the role of marine …
