Erionite has been implicated as a cause of mesothelioma. It is unclear weither this is due to fibrous, prismatic, or both forms of the mineral. The evidence to date is based on a study in Turkey. Those findings have not been supported by other areas where erionite is found, such as North Dakota and Oregon in the United States.
