The AAG’s Distinguished Lecturer for 2015-2016 is Dr. Dan Layton-Matthews of Queen’s University, Kingston, Canada. The distinguished lectures are one of AAG’s efforts to educate the existing and young upcoming geochemists that will be tomorrow’s leaders in applied geochemistry. Geology/geochemistry professors and student groups are encouraged to contact Dan(dlayton@queensu.ca) to arrange talks at their universities and institutions worldwide.

Dr. Dan Layton-Matthews’ research has traditionally been involved in genetic models of VMS, SEDEX and magmatic Ni-Cu deposits. However since his appointment at Queen’s University in 2007, he and his research group within the Queen’s Facility for Isotope Research (QFIR) have been involved in: 1) chemical indicators of mineralization in sedimentary and magmatic rocks from ore systems, 2) post-depositional chemical modification of sulfide, silicate and oxide minerals, and the chemical dispersion and physical dispersal of these minerals as indicators of mineralization in ore systems, and 3) the development of tools and concepts to aid in the discovery and understanding of formation and redistribution of ore deposits.

Dan’s current research goals, and that of his research group, are to document the background and anomalous trace element compositions and isotopic ratios of all minerals within sedimentary and magmatic rocks related to ore systems, including the mineral, elemental and isotopic transfer to surficial media. Layton-Matthews is a young and dynamic researcher and has been awarded both the William Harvey Gross and Julian Boldy Certificate awards by the Mineral Deposits Division of the Geological Association of Canada. He has active research projects on five continents that relate to geochemical exploration and the detection of buried mineralization. Dan gave his first distinguished lecture entitled “An Applied Geochemist Convert” at the 27th IAGS in Tuscon, AZ. He is currently planning several lecturer tours starting in December 2015, which will be an excellent opportunity for the applied geochemistry community to hear his presentations.
