抄録

Diopside in olivine gabbro from Horoman area, Hokkaido, has exsolution lamellae arranged parallel to the (100) diallage partings. These (100) exsolution lamellae are composed of two different lattices, i. e., a monoclinic pyroxene with space group P21/c, and an orthorhombic pyroxene with space group Pbca. These two phases may presumably be grown sub-microscopically side by side. Estimating the chemical composition of these (100) lamellae by refractive indices and lattice constants, the monoclinic pyroxene with space group P21/c is a closer member to clinoenstatite in the compositional range from clinoenstatite to pigeonite.
