Direct observation of exsolution lamellar texture with laser microscopy

Abstract

Exsolution lamellar texture of labradorite plagioclase feldspar with blue to brown-yellow iridescence can be observed directly at atmospheric condition by using laser microscopy. Shock metamorphosed texture of quartz cannot be observed as periodic and clear texture with laser microscopy.This is mainly because exsolution texture is comparatively homogeneous and smaller size with large compositional differences.
