This conversation with Dr. Nancy Chow, geologist at the University of Manitoba, is about the organics in the Duvernay and Keg River Formations.  The discussion focuses around Nancy Chow, Jack Wendte, and Lavern D. Stasiuk’s scientific research paper titled “Productivity versus preservation controls on two organic-rich carbonate facies in the Devonian of Alberta: sedimentological and organic petrological evidence”.  Some highlights include evidence for organic matter preservation due to bottom water anoxia vs high organic productivity.  May this exchange serve to expand your geological knowledge on the go.For more information go to www.stoneconsulting.infoNancy Chow, Jack Wendte, Lavern D.
