Features of the thermal water phenomena in the Khangai arch uplift (Mongolia)

Abstract

The article presents the study on the features of the thermal water phenomena in the Khangai consolidated uplift and the issues related to the conditions of their distribution. The data from the previous studies on the geological, hydrological, and hydrogeochemical aspects of the Khangai thermal waters have been collected. In accordance with to the geological-structural principle, hydrogeological zoning of Central Mongolia has been conducted and hydrogeological districts have been defined. Structural-tectonic, hydrogeological, geothermal, and gas conditions of the Khangai hydrothermal system have been studied. Thermal water reserves of certain hydrothermal deposits have been estimated. The research results on the main hydrogeological structures of Khangai and the conditions for the formation of the thermal water sources and deposits form the basis for assessing the country’s heat-and-power resources. The assessment performed for the first time, is essential for the national economy. The study has substantiated the prospects for the use of the fissure-vein waters.
