Abstract
The Kettle Point Formation is an Upper Devonian black shale that preserves the Frasnian-Famennian boundary, which marks the most extreme of the three extinction events that comprise the Late Devonian mass extinction. The purpose of this study is to determine a high resolution location of the boundary within the Gore of Chatham core from Ontario, Canada. This determination will improve the understanding of the environmental conditions leading up to the Kellwasser event of the Late Devonian mass extinction. The specific location of the boundary will also improve the ability to correlate this rock unit to others that were deposited during the same time period in different locations. The Frasnian-Famennian boundary was determined to be located at a depth of 134.59 meters in the core. The boundary is observed to have taken place during a magnetic susceptibility decrease, and therefore indicates a sea level rise.
