Karst structures in metamorphed limestone inside the xenolith of sedimentary rocks into larvikite at lake Flekkeren, Skien. Taking samples from such nice morphological outcrops should not be done! Karst is rare in Norway and destroying such nice outcrops wuold be pure vandalism. There are a lot of loose debris to collect from. Lens cap is 58 mm in diameter. Photo by Peter Andresen, 5.
