Magnetic fabric and mineralogy of cave deposits in Botovskaya Cave (Eastern Siberia, Russian Federation)
Kadlec, Jaroslav; Hercman, H.; Chadima, Martin; Lisá, Lenka; Oberhänsli, H.; Osintsev, A.
2013 - English The Botovskaya Cave is a typical example of a two-dimensional maze with a total length of explored passages exceeding 60 km, which represents the longest limestone cave system in the Russian Federation. The clastic cave sediments filling the cave passages differ in both mineral and mineral magnetic properties and were deposited under different hydrological conditions. The older portion of the clastic cave fills was derived from overlying sandstones, whereas the properties of younger cave sediments show closer affinity to the soils and weathering products originating on the sandstone plateau above the cave. The cave sediments underwent repeated periods of deposition and erosion during the Tertiary and Pleistocene. Keywords: caves; magnetic fabric; mineralogy; cave deposits Available at various institutes of the ASCR Magnetic fabric and mineralogy of cave deposits in Botovskaya Cave (Eastern Siberia, Russian Federation)

Výzkum sedimentů a speleotém ve Zbrašovských aragonitových jeskyních
Bosák, Pavel; Šlechta, Stanislav; Hercman, H.; Pruner, Petr
2013 - Czech Numerické datování termominerálních speleotém (koblih) z okolí lokality U krokodýla poskytlo poněkud starší data než dosud udávaná v literatuře: 123 až 127 tisíc let (s rozptylem 108 až 144 tisíc let). Speleotémy se tvořily v průběhu klimatického optima vrcholné poslední doby meziledové (eem), tj. v mořském izotopovém stupni (MIS) 5e. Jemnozrnné klastické sedimenty z výkopu U Krokodýla mají normální paleomagnetickou polaritu vzorků s téměř současnými paleomagnetickými směry. S ohledem na skutečnost, že sedimenty leží na bloku ze stěny utržených termominerálních speleotém, jsou pak jistě mladší než 108 tisíc let. The numerical dating of hydrothemal speleothems (doughnuts) from locality At Crocodile gave older data than was published in the literature: 123 to 127 thousand years (with range 108 to 144 thousand years). Speleothems crystallized in the time of climatic optimum of the last interglacial period (Eemian) corresponding to the marine isotope stage (MIS) 5e. Clastic sediments from excavations in the area At Crocodile show normal paleomagnetic polarity in all samples with nearly recent magnetic field directions. Studied sediments cover block of hydrothermal speleothems fallen from the wall and therefore they must be younger than 108 thousand years.

Cave formation initiated by dissolution of carbonate cement in qartzose sandstones
Adamovič, Jiří; Mikuláš, Radek; Navrátil, Tomáš; Mertlík, J.
2013 - English Besides cavities of irregular shape, European sandstones also feature symmetrical cavities of spherical, ellipsoidal or teardrop shapes. Most of them are tens of centimetres across but some reach as much as 2–3 m in diameter and may coalesce into large caves tens of metres in length. Their origin has not been clearly explained yet. Based on the field comparison between such cavities in quartzose sandstones and incompletely developed cavities in carbonate-cemented sandstones, it can be demonstrated that the symmetrical cavities form by carbonate dissolution within the limits of former carbonate concretions. The diagnostic features of post-concretionary cavities include their circular or elliptical cross-section, a uniform orientation of their long axes across the region, and the presence of a set of parallel vertical joints or grooves/ribs on their inner walls. In some sandstone areas (e.g., Petite Suisse area in Luxembourg, Kokořín area in the Czech Republic), a wide variety of transitional forms can be found between the cavities and concretions forming positive relief on a vertical cliff face, depending on the position of the carbonate dissolution front in the present landscape.

Project Namak: some of the most spectacular findings in the Iranian salt karst
Filippi, Michal; Bruthans, J.; Jager, O.; Zare, M.; Asadi, N.
2013 - English Project (“namak” means salt in Persian language) is an informal association of geologists and speleologists who cooperate on exploration and scientific research of the salt karst in southern and southwestern Iran. During the Project(from 1998 until 2013) about 16 salt diapirs were visited and more than 60 caves were discovered, 30 of which were mapped. The most exciting scientific and speleological discoveries were made in the Namakdan, Hormoz and Jahani salt diapirs; however, many other remarkable discoveries have been made on other several Iranian salt diapirs. This contribution summarizes the most interesting findings achieved during the ten expeditions carried out by the NAMAK team.

Valley incision in the Nízké Tatry Mts. (Slovakia) estimated based on paleomagnetic and radiometric cave sediment datings
Kadlec, Jaroslav; Bella, P.; Čížková, Kristýna; Granger, D. E.; Hercman, H.; Holúbek, P.; Chadima, Martin; Orvošová, M.; Pruner, Petr; Schnabl, Petr; Šlechta, Stanislav
2013 - English Up to eleven horizontal cave levels occur at different altitudes in Jánska, Demänovská and Mošnická karst valleys in the Nízke Tatry Mts. Most of the caves are filled with allochthonous sediments transported from the area formed mostly by granite. The cave levels were filled with fluvial sediments in dependence on the valleys incision caused by Neogene and Pleistocene uplift of the mountain range. The fluvial sediments are intercalated with, or capped, by flowstone layers in the caves. The paleomagnetic polarities measured both in clastic and chemogenic sediments indicate the age of deposition. Based on obtained polarity data we are able to distinguish cave sediments deposited during the Brunhes, Matuyama and Gauss chrons. The paleomagnetic interpretation was partly verified by U-series datings of flowstones preserved in the sedimentary sections. Except for the horizontal cave levels located in the karst valleys, additional large cave systems were found at extremely high altitudes in the Nízke Tatry Mts. 600–700 m above the lowest horizontal cave level.
