Open-File Report 2010-1286
Erionite, a fibrous zeolite, occurs in pediment gravel deposits near Killdeer Mountain, North Dakota. Material from these pediment deposits has been excavated for use as roadbed throughout Dunn County, North Dakota. Erionite also occurs in the Cappadocian region of Turkey, where a link between malignant mesothelioma and inhalation of this mineral has been established. The U.S. Environmental Protection Agency (EPA), Region 8, requested that the U.S. Geological Survey (USGS) compare the chemistry and morphology of erionite collected from the Killdeer Mountains to those collected from villages in Turkey and from Rome, Oregon, which has also been linked to disease in animal studies.
