Clay Minerals Short Course at the ISGS

Professor Steve Altaner of the University of Illinois Department of Geology presented a week-long short course on clay minerals at the Illinois State Geological Survey. The goal of this course was to summarize the mineralogy and chemistry of the most common clay minerals and the key physical properties of clay minerals, including environmental and societal applications; origin and occurrence of clay minerals in soil, sediment, and sedimentary rock, including examples from Illinois; and x-ray diffraction identification of clay minerals, including mixed-layer clay minerals. Twenty-eight people attended the course. For many it was the first time they were exposed to the topic of clay mineralogy and x-ray diffraction identification of clay minerals. The short course was excellent, and much positive feedback from the participants was received.
