solution channel An elongate void within a rock, which has been enlarged by the solution action of moving ground-water on the rock itself. Solution channels are most commonly associated with carbonate rocks, and groundwater in them can flow as fast as in a river on the ground surface. See KARSTIC AQUIFER.
