Abstract


PRELIMINARY PETROGRAPHIC CHARACTERISTICS OF CRYSTALLINE COMPLEX WITH CALCIPHYRES FROM THE SLYUDYANKA VALLEY (BAIKAL LAKE, RUSSIA)

Abstract. Rocks from the Slyudyanka valley (Khamar-Daban Mountain), near the Pierieval quarry, were analysed for petrographic characteristics. Rocks samples have been investigated with the use of optical and electron microscopes as well as XRD methods. The outcrops on the valley slopes reveal the presence of crystalline schists and marbles with granitoid veins. There are also calciphyres, rich in phlogopite, apatite and diopside. This complex was metamorphosed under the cordierite-biotite-almandine facies. In this rock complex, carbonate-diopside-apatite calciphyres are also present. The complex was deformed, uplifted and intruded by numerous granitoid veins during the process of tectonic rejuvenation of this area.
