Mineral Properties of Ruby Deposit in Monghsu, Myanmar

Abstract

Monghsu has been very plentiful and well-known source of the high grade ruby, However it’s mineral properties has never been systematically described in the field. This work is aimed to understanding clearly the mineral properties of Monghsu ruby deposit. Six rock specimens were collected from a mine of ruby deposit in Monghsu for study through XRD and observation of hand specimens and thin sections. The ruby orebody is mainly composed of dolomite and minor calcite, phlogopite. The country rock is mainly muscovite, calcite and minor albite. Outside of calcite is consisting of albite, phlogopite and quartz. The specimens of ruby deposit show mainly following texture types: inequigranular crystalloblastic texture, mylonitic texture.
