This conversation with Guy Plint is about the Cretaceous Dunvegan Stratigraphy. It is based on Guy Plint's scientific article  titled “Nonmarine sequence stratigraphy: updip expression of sequence boundaries and systems tracts in a high-resolution framework, Cenomanian Dunvegan Formation, Alberta foreland basin, Canada."How important are Dunvegan allomembers?  Which systems tracts are significant?  What is a lemon drop?  What's next in the Dunvegan?May this exchange serve to expand your geological knowledge on the go.For more information go to www.stoneconsulting.infoCitation: Plint, McCarthy, Faccini.
