Paleohydrogeology of the Anabar-Khatanga Basin

Abstract

The hydrogeological history of the Anabar-Khatanga basin covers the period from the Archaean to the Quaternary and includes 12 hydrogeological cycles. The Jurassic-Eopleistocene cycle is the longest during which there were continental conditions of sedimentation with the longest infiltration stage (from the Lower Cretaceous to the Neo-Pleistocene). The salts of the Devonian salt basin play a key role in the formation of the groundwater and brines composition within the following structures: Nordvik, Southern Tigyan, Ilya Kozhevnikova, Ledovka and Belaya.
