Abstract

A new Cr-dominant calcic amphibole with NaCa2Mg4CrSi6Al2O22(OH)2 composition from Akaishi mine was named as ehimeite for the locality, Ehime. The mineral data and the name have been approved by the Commission on New Minerals and Mineral Names of the International Mineralogical Association (no. 2011-023). The type specimen is deposited at the National Science Museum, Tokyo, under the registered number NSM-M 41160. Here, we describe a new Cr-dominant member amphibole, ehimeite.
