Role of Periglacial Processes in Epikarst Morphogenesis: A Case Study from Chełm Chalk Quarry, Lublin Upland, Eastern Poland
Pocket forms several decimetres in diameter, 0.5–1.5 m deep and infilled mainly with glaciogenic sands, silts and clays of Saalian age are commonly developed on the top of the karstified chalk massif of the Lublin Upland, eastern Poland. Analysis of lithofacies, particle‐size distribution and microm...
