Uncovering A Missouri Meteorite Crater – The Weableau Impact Structure
by
Dr. Kevin R. Evans
Missouri State University
While many craters on the Moon are visible in even small telescopes, craters on the Earth are far fewer and much harder to see. Most of them have been covered up by erosion, movement of the Earth’s surface, and vegetation. Some ancient craters have been uncovered by geologists who have precisely mapped the surface and analyzed unusual rock formations and composition. One such crater, thought to have formed over 340 million years ago, is hidden away in Saint Clair County, Missouri. It is the Weableau Impact Structure, named for the nearby town, which is about 50 miles north-northwest of Springfield, Missouri. Dr. Evans has mapped the central crater and studied the broken and melted rocks formed in that ancient impact. He will talk about how he studies Earth’s ancient craters, and what he has discovered about the Weableau.
Kevin Evans is a professor in the Department of Geography, Geology, and Planning at Missouri State University, Springfield, MO. His research interests include meteorite impacts, carbonate depositional systems, and sequence stratigraphy.
