  • Resumen
    • Large-scale salt dissolution is an important process affecting the sediments of many of the saline lakes in the northern Great Plains region of western Canada. The most easily recognized features of this salt karst are water-filled chimneys, vertical shafts, and collapse structures. The largest individual chimneys can be up to 20 m deep and 50 m in diameter, with volumes exceeding 25,000 m3. Large, mud-filled chimneys and cavities, and salt-filled chimneys have also been identified in both the modern lakes and in the Quaternary sediments of the basins, which can adversely affect the salt mining potential of the basins. Because these salt karst features can affect large vertical sections of the sediment fill in the lakes, their recognition is of fundamental importance in attempting to use the stratigraphic records of the basins for paleoenvironmental research.
