Dangerous dust: Erionite - an asbestos-like mineral causing a cancer epidemic in Turkey - is found in at least 13 states

As North Dakota’s state geologist, Ed Murphy has spent a fair amount of time mapping the geology of the Killdeer Mountains in the western part of the state, hiking up and down buttes of the White River Group and the Arikaree Formation. In the 1980s, he and colleagues mapped large deposits of rocks bearing erionite — a zeolite mineral formed when volcanic ash is altered by water — that may have had some commercial use.
