Fieldwork in the Wind River Basin, WY

Ran, Miquela, and collaborator Brian Currie spent a week in the Wind River Basin, Wyoming to collect Paleocene Fort Union siderite nodules in outcrop. This sampling was a part of Ran's work understanding the impact of shallow, low-temperature diagenesis via meteoric water on iron carbonates. Ran will combine petrographic observations and stable isotopic compositions (C, O and ∆47) to reconstruct the diagenetic history of the outcrop siderites, and compare them to our cores of the same strata to investigate meteoric versus deep burial alteration.
