Abstract
Summary
The method and results of modelling the hydrogeochemical spatial patterns in the Cretaceous and Jurassic sediments of the Koltogor and Tolkin troughs and surrounding areas of the West Siberian megabasin are presented. The model of hydrogeochemical conditions is constructed as series maps of the groundwater salinity in Formations, as well as NS and EW oriented cross-sections. Results indicate a significant variability of groundwater salinity both as a whole in the Jurassic-Cretaceous sediments, and within individual aquifer. The revealed substantial heterogeneity of hydrogeochemical conditions in the Jurassic-Cretaceous sediments indicates the complex genesis of the groundwater chemical composition.
