Director: Patrick McLaughlin
Other Researchers: Thijs Vandenbroucke Ghent University Belgium Matthias Sinnesael University of Brussels (PhD student)
Funding: Indiana University - Indiana Geological & Water Survey
Issue: The study of ancient mass extinctions is hindered by our ability to date the rocks that preserve extinction record. This technique has been used in the Cenozoic and there is theoretically no reason why it should not work here.
Objective: Lots of pXRF analysis and mentoring of two undergraduates.
Approach: Photograph the core and then analyze it with the pXRF at 3" intervals through the full ~1000' of the Upper Ordovician.
Products: NSF proposal and professional journal article. 90 day after end of project final report due to OVPR
Benefits: Demonstration of the incredible value of IGS collections to answer pertinent questions about Earth history. Use of a new technology to generate a very detailed analysis of Upper Ordovician shale composition--the source rocks of the Trenton Field and a major regional aquitard.
