  • COEXISTING 3T AND 2M<sub>1</sub> MUSCOVITES IN THE SANBAGAWA SCHISTS

Abstract

Muscovites from the Sanbagawa schists exhibit a wide range of 2Vx, from 0° to 40°, even in a hand specimen and often in a single muscovite flake. This is due to the superposition of 3T and 2M1 polytypes of muscovite, sometimes in a scale larger than the wavelength of visible light, and sometimes less than that. Chemical environments and metamorphic grade show no preference to the types of polytypes in the range of metamorphic grade covering the glaucophane schists and epidote amphibolite facies.
