The Burren: a glacial, karstic and biokarstic expression of a limestone plateau in western Ireland
Abstract The term glaciokarst describes a landscape where both glacial and karstic processes have contributed to geomorphological evolution and has been applied to a range of environments from the high arctic to the alpine Mediterranean. Nevertheless, glaciokarstic environments globally often exhibi...
