Noel James, Professor of Geology at Queen sUniversity, Canada, has, for over 40 years focused his research oncarbonate sediments and rocks that range from the modern seafloorto the Archean, studying their origin via extensive marine andterrestrial fieldwork, petrography, and geochemistry. He has taught numerous courses on oceanography, carbonatesedimentology, petroleum geology and the evolution of North Americato undergraduates, graduate students, and professionals as well asediting or authoring nine scientific books. He has beenhonoured many times by learned societies, is a Fellow of the RoyalSociety of Canada, and a Member of the Order of Canada. Brian Jones, Distinguished University Professor (Geology) atthe University of Alberta, Canada, has, for over 40 years taughtnumerous courses at the introductory and advanced level oncarbonate sedimentology and diagenesis. His research oncarbonates has concentrated on the deposition and diagenesis ofmodern and Cenozoic deposits in the Caribbean, surface andsubsurface Paleozoic rocks in the Western Canadian SedimentaryBasin, many of which are prolific hydrocarbon reservoirs, andspring deposits worldwide. He is a Fellow of the Royal Society ofCanada, and the first Middleton Medalist of the GeologicalAssociation of Canada.
