ATL Senior Geologist Chris Kelson, PhD, PG, gave a presentation at this years’ Geology Days Conference. The conference took place from November 11th to 13th in Saratoga Springs, NY, and consisted of presentations and a panel discussion with members of the State Board for Engineering, Land Surveying, and Geology to answer questions from attendees.

Chris presented “Pyrite and Pyrrhotite in Shale, Fill Material, and Aggregate: A Potential Geotechnical Concern.” This presentation provides an overview of the mineralogy and geological occurrences of pyrite and pyrrhotite and the geochemical and environmental factors that contribute to the deleterious effects sometimes associated with these minerals. We’re so proud that our employees are presenting at conferences all over the country. Congratulations Chris!
