||The Silurian rocks and fossils of Indiana contain geologic patterns that can inform outstanding questions about how the ocean-atmosphere system responds to change.
||Complete a Sr-isotope curve for southern Indiana tied to previously collected geochemistry.
||Isolate conodont specimens and supporting documentation from the archived Rexroad collection. Collect additional brachiopod samples from outcrops at Sellersburg, Atkins, and Speed quarries. Review conodont materials with Bancroft at IGS before sending samples to Emsbo for analysis.
||Peer reviewed publication.
||-This project informs fundamental knowledge gaps in the response of the ocean-atmosphere system to disruption.
-The analytical and stratigraphic techniques are highly advanced and will demonstrate the capacity of the IGS to contribute/lead in these areas of research.
-This study will provide a pilot project for the utilization of archived IGS conodonts in chemostratigraphic studies.
