    Lava tubes and caves, when accessible for man, are very common in volcanic environments and poorly known to non-specialists. This short overview presents the distribution and forms of lava tubes, their speleothems and mineralogy and modes of formation. Studies of lava caves outside of Earth currently are a topic of great interest, as they may be potential locations for some life forms and future bases in space exploration. Basic features of lava tubes are illustrated with reference to the longest lava cave in the world, Kazumura Cave, in Hawaii.

    Opis:
    Czarna Cave represents phreatic cave with multiple loops. No cave level developed at the water table was detected. The cave was later modified by invasion vadose waters and breakdown processes. The phreatic paleoflow directions were analyse from the asymmetry of scallops. The paleoflow was directed from the east to the west, that is in a direction of the Kościeliska Valley. Therefore, this valley represented the main discharge zone of the region during the formation of Czarna Cave.

    Opis:
    The Hoher Göll Massif is situated 20 km south of Salzburg and belongs to the Northern Calcareous Alps (Austria). It is a ridge ca. 11 km long and 3 km wide with the highest summit Hoher Göll (2522 m a.s.l.), encircled by deeply incised valleys with bottoms ca. 2,000 m below it. Cave clastic deposits were studied in the Hochschartehöhlensystem, Dämchenhöhle and Hintere caves. The caves belong to the Giant Cave Level, with the exception of part of the Hochschartehöhlensystem, that is Der Sprechender Steine Cave, the highest parts of which belong to the Ruin Cave Level. The sources of the cave sediments have been identified from the composition of the heavy fractions. Preliminary studies of the Hoher Göll caves reveal that the cave fills were derived from the Oligocene to earliest Miocene Augenstein Formation, the deposits of the Palaeo-Inn River and the siliciclastic basal strata of the Northern Calcareous Alps. The clastic material deposited as the Augenstein Formation was transported from southern parts of the Eastern Alps and by the Palaeo-Inn river from their western part. According to heavy minerals, the sources of the clastic material were on the Palaeozoic terrains, the post-Palaeozoic sequence, and the Middle Austroalpine Unit. Later, during or after the mountain uplift, weathered materials from the Augenstein and Palaeo-Inn deposits were eroded and transported from the surface into caves by allogenic streams. Some of the sediments were likely to have been transported later to the Giant Cave Level from the southern part of the Northern Calcareous Alps.

    Opis:
    Tectonic research and morphological observations were carried out in six caves (Kalacka, Goryczkowa, Kasprowa Niżna, Kasprowa Średnia, Kasprowa Wyżnia and Magurska) in the Bystra Valley, in the Tatra Mountains. There are three cave levels, with the youngest active and the other two inactive, reflecting development partly under epiphreatic and partly under phreatic conditions. These studies demonstrate strong control of the cave pattern by tectonic features, including faults and related fractures that originated or were rejuvenated during uplift, lasting from the Late Miocene. In a few local cases, the cave passages are guided by the combined influence of bedding, joints and fractures in the hinge zone of a chevron anticline. That these cave passages are guided by tectonic structures, irrespective of lithological differences, indicates that these proto-conduits were formed by “tectonic inception”. Differences in the cave pattern between the phreatic and epiphreatic zones at a given cave level may be a result of massif relaxation. Below the bottom of the valley, the effect of stress on the rock mass is related to the regional stress field and only individual faults extend below the bottom of the valley. Thus in the phreatic zone, the flow is focused and a single conduit becomes enlarged. The local extension is more intense in the epiphreatic zone above the valley floor and more fractures have been sufficiently extended to allow water to flow. The water migrates along a network of fissures and a maze could be forming. Neotectonic displacements (of up to 15 cm), which are more recent than the passages, were also identified in the caves. Neotectonic activity is no longer believed to have as great an impact on cave morphology as previously was thought. Those faults with displacements of several metres, described as younger than the cave by other authors, should be reclassified as older faults, the surfaces of which have been exposed by speleogenesis. The possible presence of neotectonic faults with greater displacements is not excluded, but they would have had a much greater morphological impact than the observed features suggest.

    Kraków-Wieluń Upland
    Opis:
    The chemical composition of the water in Smocza Jama cave (city of Kraków, Kraków-Wieluń Upland) was studied. The cave is 276 m long and it was developed in the Upper Jurassic limestone. Nineteen water samples were collected between March 1995 and January 1998. The pool water and drip water were sampled. The former water samples represent Ca - Na - HCO3 - SO4 - Cl, while the latter ones SO4 - Ca - Na type. In pool water the concentrations of Cl are higher than in drip water, while in drip water the SO4 predominates. The chemical composition of the studied samples of both the pool and drip waters differs considerably from the composition typical of the limestone cave water. The studied water differs also in its chemical composition from the ground- water of the Kraków-Wieluń Upland. High concentrations of NO3, SO4, Cl, Na, K, and P suggest that the water in Smocza Jama is considerably affected by pollution. The chemical composition of the studied pool water can be the effect of mixing of, at least, two components. The water can: (i) filtrate from the Vistula river, (ii) percolate down from the surface of Wawel Hill, (iii) migrate from the nearby area, where the city centre is located, and (iv) ascend as artesian water from deeper confined aquifer. The former three of the four mentioned water sources may be strongly degraded due to long lasting human occupation of both Wawel Hill and the city centre, as well as pollution of the Vistula river. The high amount of SOS ions reaching 1439 mg/L in drip water results probably from leaching of litter and rubble poured over the cave in the 19th century.
    Jaskinia Smocza Jama jest usytuowana w centrum Krakowa, w południowej częoeci Wyżyny Krakowsko-Wieluńskiej (Fig. 1, 2). Powstała ona w wapieniach jury górnej budujących niewielki zrąb otoczony głównie iłami mioceńskimi znajdującymi się w sąsiednich rowach tektonicznych. W jaskini występują jeziorka (Fig. 3); ich powierzchnia położona jest w przybliżeniu na poziomie wód Wisły, która płynie w odległości ok. 50 m od jaskini. Fluktuacje poziomu wody w jaskini nawiązują do zmian poziomu wody w Wiśle (Kleczkowski, 1977). Badane było szesnaście próbek wody pobranych z jeziorek i trzy próbki wody kapiącej ze stropu jaskini (Fig. 3). Wszystkie próbki reprezentowały wody słabo alkaliczne. Mineralizacja ogólna wód z jeziorek była mniejsza niż wody kapiącej. W pierwszym przypadku wynosiła od 779,25 mg/L do 1013,01 mg/L podczas gdy w drugim od 1752 mg/L do 2841,73 mg/L (Tabela 1).

    Opis:
    Heavy, black manganese pebbles have been found in the clastic sediments of the Hochschartehöhlensystem (the Northern Calcareous Alps). Six selected pebbles were subjected to X-ray diffraction, optical microscopy and optical and electron microscopy analysis. The results reveal that the main component of the pebbles is manganese silicate, braunite, Mn2+Mn3+6(SiO4)O8. Braunite is a mineral formed at elevated temperatures, mainly through hydrothermal, metamorphic or diagenetic processes. This means that the manganese pebbles were formed outside the caves. However, manganese rock was not found in situ on the surface of the Hoher Göll Massif. This probably indicates that their origin is from eroded parts of Mesozoic rocks. The first studies of pebbles and their mineralogy, by analogy with contemporary marine sediments, indicate that their genesis is related to spreading zones and accompanies hydrothermal vents. The analysed material highlights two important issues: (1) the manganese pebbles are significant arguments for the occurrence of hydrothermal vents in the Northern Calcareous Alps; and (2) the importance of cave sediments studies, which provide relevant evidence for palaeogeographic reconstruction.

    Opis:
    Although Dobšina Ice Cave (DIC, Carpathians, Slovakia) is located outside the high-mountain area, it hosts one of the most extensive blocks of perennial subterranean ice, the volume of which is estimated at more than 110,000 m3. Frozen bat remains were found in the lowermost part of the perennial ice block. They belong to Myotis blythii (Tomes) and the M. mystacinus morpho-group. The radiocarbon dating of bat soft tissues yielded ages of 1266–1074 cal. yr BP and 1173–969 cal. yr BP. The undetermined bat, found in the same part of the ice section in 2002, was previously dated at 1178–988 cal. yr BP (Clausen et al., 2007). The dates testify that the ice crystallized at the turn of the Dark Ages Cold Period and the Medieval Warm Period. The calculated accumulation rate of cave ice varies between 0.7 cm/year and 1.4 cm/year at that time, and is similar to the present ice accumulation rate in DIC. Constant crystallization of ice during the Medieval Warm Period is hypothesized to reflect dry summer seasons since the supply of relatively warm water in the summer is one of the key factors causing the erosion of cave ice. The uppermost sample was covered with 20.6 m of ice. Between ca 1065 cal. yr BP and the present day, the ice grew faster than between ca 1210 yr BP and ca 1065 yr BP by a factor of 1.3–1.8. This may have resulted from conditions favourable for ice accumulation during the Little Ice Age.

    Opis:
    The origin and age of cave deposits, as well as palaeogeographical changes in the Bystrej catchment during the last ca. 250 ka, were reconstructed in Magurska, Kasprowa Niżnia, Goryczkowa, Kalacka and Bystrej caves (the Bystrej Valley). The reconstruction is based on the study of corrosive forms, heavy mineral analyses and U-series dating of speleothems. Two generations of palaeoflows were distinguished by observations of scallops and heavy mineral analyses. In the older stage, now abandoned caves drained massifs surrounding the Bystrej Valley and part of an adjacent valley. The direction of palaeoflow changed as a result of the water capture after Kasprowa Niżnia Cave came into being. In the later stages, the evolution of cave systems was controlled by glaciation-deglaciation cycles. Probably at this time, some caves located in the lowest parts of the massifs also started to be formed. U-series speleothem dating allows the determination of five phases of speleothem deposition: ca. 220–150 ka, ca. 135–105 ka, ca. 95–70 ka, ca. 40–23 ka and during the Holocene.
