On Minerals Associated with Ultrabasic Rocks, Found in the Vicinity of Commom Boundaries of Shimane, Tottori, Okayama, and Hiroshima Prefectures(VIII) : Ca-montmorillonite from the Hirose Mine, Tottori Prefecture
Description
A Ca-montmorillonite has been altered from pyroxenite. The Ca-montmorillonite described in the paper is associated with a smal amount of diopside. X-ray, differential thermal and chemical data of the Ca-montmorillonite are presented. A part of Ca occupies octahedral site replacing Mg^<+2>, and the exchangeable capacity of Ca presented in inter-layer is lrage.
