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.
