Unusual iron cycling and clay mineralogy in Cambrian shales
Iron speciation analysis produced strange results for the green shales of the Cambrian Harkless Formation. I seek to understand how iron-rich clays affect the iron speciation paleoredox proxy.
Facies analysis of the Cambrian SPICE event in Appalachia
I seek to understand how paleoenvironmental changes may or may not have distorted the expression of the SPICE event across Appalachia.
