РАДОНОВЫЕ ВОДЫ БОЛЬШОЙ БЕЛОКУРИХИ: СОВРЕМЕННОЕ ИСПОЛЬЗОВАНИЕ И ПЕРСПЕКТИВНЫЕ УЧАСТКИ РАЗВИТИЯ КУРОРТА

Abstract

At present, a tourist and recreational cluster is being formed around the federal resort of Belokurikha, which includes the adjacent territories of the Smolensk, Altai and Soloneshensky municipal districts of the Altai Territory. To determine the directions of spatial development in the cluster, information is needed on the prospects for discovering new sources of radon waters. The purpose of the study is to assess the current level of use of radon waters by the resort of Belokurikha, to identify geological and geochemical prospecting indicators of radon waters and to assess the prospects for their detection within the tourist cluster "Bolshaya Belokurikha". A field study of the territory and sampling of granitoids from the Belokurikhinsky pluton were carried out. The analysis of isotopes of uranium and thorium from granitoids was carried out according to the classical method at the Center for Isotope Research of the Russian Geological Research Institute (St. Petersburg). The analysis of the current water use was carried out based on the data of the Hydroservice of the resort of Belokurikha on water consumption for 2019. The volume of radon water consumption by the sanatoriums of the Belokurikha resort in 2019 varied throughout the year from 435.1 m3 / day in August to 282.1 m3 / day in December. This does not exceed the operational reserves of the Belokurikhinskoye deposit, which are 600 m3 / day. Potential areas for the detection of radon waters are confined to the deep sub-latitudinal Belokurikha fault, which runs along the border of the Pre-Altai plain and the Altai Mountains, and especially to the zones of intersection of faults of different directions. This is the main geological prospecting indicator. The geochemical prospecting indicator is the increased content of uranium in rocks. The highest concentrations of 238U and 232Th isotopes in the granitoids of the Belokurikhinsky pluton were found for aplites and pegmatites. Thus, the entire strip of the transition zone from the Biysk-Barnaul depression to the mountain-folded structure of Altai has prospects for radon waters, due to a complex of features for prospecting and factors of water formation with the participation of the vadose component and of deep waters leaching minerals with increased radioactivity from aplites and pegmatites. Prospective sites for carrying out detailed prospecting for radon waters are located in Belokurikha-2 in the area of the village Ulyanovka and near the village of Danilovka. Here, in addition to indirect prospecting indicators, there are also direct ones (radon content in waters).
