The "unroofed cave" near the bunker (Laški Ravnik), 1999, Gerš, L Milan, Stepiš, Nik Uroš, , Š, Uš, Terš, Ič, Simona

Situated in the Laški Ravnik, about 4 km east of Planinsko polje (Slovenia), this unroofed cave is the longest of many found in the area. More than 200m of denuded passage has been traced at the surface. The cave's general trend is north - south. Three main "passages" making up the unroofed cave have been recognised, and each has been transformed in its own way. Disintegration of parts of the former cave roof is apparent, forming "false solution dolines", between which the ceiling is partly preserved, either in-situ or as isolated blocks lying on cave sediment. In the down-dip direction, passage sides have disintegrated almost completely, and detached blocks have slid down into washed-out portions of the former cave passages. All three passages developed along bedding planes, but in different directions, such that two of them now "emerge" above the surface whereas the third plunges down and is completely choked by loam. The unroofed cave passes southwards into a "normal" underground route, where a barely accessible, low and wide passage is accompanied by two "vertical" shafts, which are presumed to be former phreatic jumps. This part of the system is not considered in this paper.


Pleistocene depositional history in a periglacial terrane: A 500ka record from Kents Cavern, Devon, United Kingdom., 2007, Lundberg, J. And Mcfarlane, D. A.
The signifi cance of the stratigraphic record in Kents Cavern, Devon, United Kingdom, to the interpretation of the British Quaternary is confi rmed on the basis of a thorough reexamination of the deposits in concert with 2 new Al-Be cosmogenic and 34 new thermal ionization mass spectrometry U-Th dates. The deposits show evidence of complex reworking in response to periglaciation, and the main fl owstone deposit is a multilayered complex spanning marine isotope stage (MIS) 11?3. The lowermost unit of fl uvial sands is Cromerian or older. The second deposit, a muddy breccia of surfi cial periglacial solifl uction material containing Acheulian artifacts, entered the cave during MIS 12 from highlevel openings to the west. Cave bears denned in the cave during MIS 11, the Hoxnian interglacial; their bones are capped by an MIS 11 calcite fl owstone layer. From MIS 11 onward, each interglacial period and the warmer interstadial periods (MIS 11, 10b, 9, 7, 6b, 5, and 3) produced calcite fl owstone deposition in the cave; MIS 9 was particularly active. Each glacial or stadial period (MIS 10c, 10a, 8, 6c, 6a, 4, and 2) caused periglacial activity in the cave, during which the thinner layers of calcite were fractured by frost heave and redistributed by solifl uction. This sequence was interrupted during MIS 3?2 with the introduction of sandy and stony clastic sediments from entrances to the east, and fi nally cemented by the uppermost layer of MIS 1 fl owstone. This is the fi rst publication of welldated and clearly documented evidence of frost heaving in interior cave passages. The Kents Cavern record of continuous, repeated sedimentation events followed by frost shattering and remobilization events over the past 500 k.y. is probably unique in the karst literature and establishes Kents Cavern as a site of international scientifi c interest.

Paleomagnetic Records in Cave Sediments, 2012, Sasowsky, Ira D.

The Earth’s magnetic field reverses polarity at irregular intervals in the range of a few hundred thousand years. Magnetic mineral grains suspended in cave waters orient themselves with respect to the prevailing field direction when they settle from the water and then become locked in place in the resulting pile of cave sediment. Because the time scale of magnetic reversals is well-established, measurement of magnetic orientation in cave sediments and the location of magnetic reversals within sediment piles can be used to date the deposits and thus provide a minimum age for the cave.
