Cementation of Solution-Collapse Breccias in the Lower Ordovician Upper Knox Group, Central Tennessee

Thomas R. Quintero, J. Richard Kyle, Nathan Miller, Estibalitz Ukar

Studying the paragenesis and microstratigraphy of carbonate hosted “Mississippi Valley-type” solution-collapse breccia orebodies provides insight into important regional characteristics and processes: Relative age of MVT mineral precipitation with respect to its hosting mineral cements and Evolution of porosity in the Upper Knox Group reservoir. Here we use Optical Cathodoluminescence (CL) combined with LA-ICP-MS analysis, High Resolution X-ray Computed Tomography, and SEM-CL images to define zones of dolomite quantitatively in order to constrain the evolution of local and regional.

Great poster and video — thank you for sharing this work! You make the processes for “reading” rocks clear and easy to understand for a non-expert. Why did you choose your specific research site? —Jeanette Herman

Thanks for sharing this work, and especially for sharing the video — it makes the research questions (and their eventual implications) really clear! —Rob Reichle
