Abstract

ABSTRACT: : This paper analyzed the physico‐chemical characteristics of natural waters in a drainage system of the Jungar Basin, northwestern China to identify chemical evolution and recharge mechanisms of natural waters in an arid environment. The waters studied are different in mineralization, but are typically carbonate rivers and alkaline in nature. No Cl‐dominated water type occurs, indicating an early stage of water evolution. Regolith and geomorphological parameters controlling ground‐surface temperature may play a large role in the geological evolution of the water. Three main morphological and hydrological units are reflected in water physico‐chemistry. Climate influences the salinization of natural waters substantially. Direct recharge from seasonal snow and ice‐melt water and infiltration of rain to the ground are significant recharge processes for natural waters, but recharge from potential deep groundwater may be less important. The enrichment of ions in lakes has been mainly caused by evaporation rather than through the quality change of the recharged water.
