GEOCHEMICAL FEATURES OF NATURAL WATERS IN THE CENTRAL ECOLOGICAL ZONE OF THE BAIKAL NATURAL TERRITORY (BNT)

ABSTRAСT: The paper describes the composition of stable components association of the CEZ BNT thermal waters components. It includes Li, B, Na, Si, K, Rb, Sr, Mo, and W. Significant depth formation of the thermal and the pres-ence of this association or its fragments in another type natural waters (e.g. surface, ground) allows to predict that the waters have deep nutrition. A comparison of the distribution of natural waters components concentration allows to as-sume that atmospheric water supply and host rocks are the only source of the waters formation. The distribution of the composition of thermal waters components concentration is related to the temperature and duration of contact with the host rocks.
