Apparent Glacially Induced Structural Controls On Limestone Conduit Development In Ohio Caverns, United States, Adrienne M. Watts, Ira D. Sasowsky
Apparent Glacially Induced Structural Controls On Limestone Conduit Development In Ohio Caverns, United States, Adrienne M. Watts, Ira D. Sasowsky
International Journal of Speleology
Rock discontinuities such as bedding planes and joints are important controls on the form that caves take. We examined structural controls on the development of Ohio Caverns. The cave formed in Devonian limestone underlying a small bedrock knob (Mt. Tabor) within the Interior Lowland province, United States. The area has been overridden by continental glaciation multiple times. The bedrock is pervasively fractured, with many curved and wavy near-vertical fractures showing many different orientations. In the case of Ohio Caverns, it appears that the controlling fractures in map view may not be joints sensu stricto, but rather some combination of …

International Journal of Speleology
Lava tubes and channels forming lava distributaries have been recognized from different parts of western Deccan Volcanic Province (DVP). Openings of smaller dimension have been documented from the pāhoehoe flows around Pune, in the western DVP. A small lava cave is exposed in Ghoradeshwar hill, near Pune. Detailed field studies of the physical characteristics, structure and morphology of the flows hosting the lava tube has been carried out. This is the first detailed documentation of a lava cave from the DVP. The lava cave occurs in a compound pāhoehoe flow of Karla Formation, characterized by the presence of lobes, toes …
Hydrothermal Speleogenesis In Carbonates And Metasomatic Silicites Induced By Subvolcanic Intrusions: A Case Study From The Štiavnické Vrchy Mountains, Slovakia, Pavel Bella, Ľudovít Gaál, Vladimír Šucha, Peter Koděra, Rastislav Milovský
Hydrothermal Speleogenesis In Carbonates And Metasomatic Silicites Induced By Subvolcanic Intrusions: A Case Study From The Štiavnické Vrchy Mountains, Slovakia, Pavel Bella, Ľudovít Gaál, Vladimír Šucha, Peter Koděra, Rastislav Milovský
International Journal of Speleology
Several caves of hydrothermal origin in crystalline limestones and metasomatic silicites were investigated in the central zone of the Štiavnica stratovolcano, Štiavnické vrchy Mountains, central Slovakia. Evidence of hydrothermal origin includes irregular spherical cave morphology sculptured by ascending thermal water, occurrence of large calcite crystals and hydrothermal alteration of host rocks, including hydrothermal clays. The early phases of speleogenesis in the crystalline limestone near Sklené Teplice Spa were caused by post-magmatic dissolution linked either to the emplacement of subvolcanic granodiorite intrusions during Late Badenian time or to the spatially associated Late Sarmatian epithermal system. Speleogenesis in metasomatic silicites in the …
Cave Monitoring And The Potential For Palaeoclimate Reconstruction From Cueva De Asiul, Cantabria (N. Spain), Andrew C. Smith, Peter M. Wynn, Philip A. Barker, Melanie J. Leng, Steve R. Noble, Andrew Stott
Cave Monitoring And The Potential For Palaeoclimate Reconstruction From Cueva De Asiul, Cantabria (N. Spain), Andrew C. Smith, Peter M. Wynn, Philip A. Barker, Melanie J. Leng, Steve R. Noble, Andrew Stott
International Journal of Speleology
Palaeoclimate records from northern Iberia are becoming increasingly sought after as this region is one of the most southerly terrestrial locations in Europe to have its climate dictated principally by the North Atlantic. Terrestrial records therefore have the potential to offer insights into changing oceanic and atmospheric circulation in the wider North Atlantic region. Cave speleothems offer one of the most promising archives from northern Iberia due to their wide geographic distribution and potential for accurately dated climate reconstruction. Cueva de Asiul, situated in Cantabria (N. Iberia; 43°19'0.63''N, 3°35'28.32''W; 285 m.a.s.l) within the Matienzo karst depression is one such site …
Cave Development In An Uplifting Fold-And-Thrust Belt Of The Tatra Mountains, Poland, Jacek Szczygieł
Cave Development In An Uplifting Fold-And-Thrust Belt Of The Tatra Mountains, Poland, Jacek Szczygieł
International Journal of Speleology
Detailed structural analysis and geomorphological observations supplemented by the analysis of the distribution of karst conduit directions have been performed in 23 morphologically diverse caves in the Tatra Mountains. Based on these studies, a development scheme of vadose cave passages has been proposed for the most common geological settings in the fold-and-thrust-belt: (1) single-plain faults, (2) multiple fault cores, (3) bedding plane fractures and (4) hinge zones of recumbent folds. Results indicate that the dynamics of the massif (local gravity sliding in the nearby slope zone and regional stress fields), along with the structural pattern, influences the predisposition of structural …
A New Microenvironment For The Formation Of Clay Minerals: The Example Of Authigenic Halloysite-7Å And Gibbsite In A Stalactite From Agios Georgios Cave, Kilkis, North Greece, Elena Ifandi, Basilios Tsikouras, Dimitrios Papoulis, Konstantin Hatzipanagiotou, Aspasia Antonelou
A New Microenvironment For The Formation Of Clay Minerals: The Example Of Authigenic Halloysite-7Å And Gibbsite In A Stalactite From Agios Georgios Cave, Kilkis, North Greece, Elena Ifandi, Basilios Tsikouras, Dimitrios Papoulis, Konstantin Hatzipanagiotou, Aspasia Antonelou
International Journal of Speleology
An unusual authigenic origin for halloysite and gibbsite is reported in a stalactite from Agios Georgios Cave, Kilkis. This speleothem includes mostly pure calcite whereas minor areas of Mg-rich calcite and scarce dolomite are present in four growth phases. Abundant pores are created due to imperfect coalescence of the calcite crystals. Several of them contain detrital muscovite, which was presumably transferred from the dripping water, during the formation of speleothem and has been variably altered to halloysite. Several pores in the stalactite contain different mineral assemblages that we interpret as in situ: halloysite-7Å, halloysite + silica, gibbsite + silica and …
Speleogenesis Of The Hermannshöhle Cave System (Austria): Constraints From 230Th/U-Dating And Palaeomagnetic Analysis, Lukas Plan, Andrea Schober, Denis Scholz, Christoph Spötl, Petr Pruner, Pavel Bosák
Speleogenesis Of The Hermannshöhle Cave System (Austria): Constraints From 230Th/U-Dating And Palaeomagnetic Analysis, Lukas Plan, Andrea Schober, Denis Scholz, Christoph Spötl, Petr Pruner, Pavel Bosák
International Journal of Speleology
Hermannshöhle is a show cave located near Kirchberg/Wechsel in Lower Austria. Together with three nearby and genetically connected caves, it forms the Hermannshöhlen cave system (HHS). With a length of 5 km, the HHS is the longest cave in the Lower Austroalpine unit. It is arranged as an extreme three-dimensional maze on a ground area of 200 x 200 x 82 m. Speleothems are abundant in this cave and represent the focus of this study. Low carbon isotope values indicate the presence of a soil-covered catchment above the HHS during times of speleothem deposition. 28 samples were dated by the …
Late Quaternary Speleogenesis And Landscape Evolution In A Tropical Carbonate Island: Pango La Kuumbi (Kuumbi Cave), Zanzibar, Nikos Kourampas, Ceri Shipton, William Mills, Ruth Tibesasa, Henrietta Horton, Mark Horton, Mary Prendergast, Alison Crowther, Katerina Douka, Patrick Faulkner, Llorenç Picornell, Nicole Boivin
Late Quaternary Speleogenesis And Landscape Evolution In A Tropical Carbonate Island: Pango La Kuumbi (Kuumbi Cave), Zanzibar, Nikos Kourampas, Ceri Shipton, William Mills, Ruth Tibesasa, Henrietta Horton, Mark Horton, Mary Prendergast, Alison Crowther, Katerina Douka, Patrick Faulkner, Llorenç Picornell, Nicole Boivin
International Journal of Speleology
Kuumbi Cave is one of a group of caves that underlie a flight of marine terraces in Pleistocene limestone in eastern Zanzibar (Indian Ocean). Drawing on the findings of geoarchaeological field survey and archaeological excavation, we discuss the formation and evolution of Kuumbi Cave and its wider littoral landscape. In the later part of the Quaternary (last ca. 250,000 years?), speleogenesis and terrace formation were driven by the interplay between glacioeustatic sea level change and crustal uplift at rates of ca. 0.10-0.20 mm/yr. Two units of backreef/reef limestone were deposited during ‘optimal’ (highest) highstands, tentatively correlated with MIS 7 and …

Large-Scale And High-Resolution 3-D Cave Mapping By Terrestrial Laser Scanning: A Case Study Of The Domica Cave, Slovakia, Michal Gallay, Ján Kaňuk, Zdenko Hochmuth, John D. Meneely, Jaroslav Hofierka, Vladimír Sedlák
Large-Scale And High-Resolution 3-D Cave Mapping By Terrestrial Laser Scanning: A Case Study Of The Domica Cave, Slovakia, Michal Gallay, Ján Kaňuk, Zdenko Hochmuth, John D. Meneely, Jaroslav Hofierka, Vladimír Sedlák
International Journal of Speleology
Mapping and modelling the complicated geometry of caves is a challenging task that has traditionally been undertaken by tacheometric surveying methods. These methods are excellent for capturing the general shape of a cave system but they are not suitable for high-speed, high-resolution mapping of complex surfaces found in this environment. Terrestrial laser scanning (TLS) technologies can acquire millions of points represented by 3-D coordinates, at very high spatial densities on complex multifaceted surfaces within minutes. In the last few years, advances in measurement speed, reduction in size / cost and increased portability of this technology has revolutionised the collection of …
Underground Fieldwork – A Cultural And Social History Of Cave Cartography And Surveying Instruments In The 19th And At The Beginning Of The 20th Century, Johannes Mattes
Underground Fieldwork – A Cultural And Social History Of Cave Cartography And Surveying Instruments In The 19th And At The Beginning Of The 20th Century, Johannes Mattes
International Journal of Speleology
At the turn of the 20th century, the practical examination of caves went through a radical change. Governmental organizations and private clubs were founded in an attempt to establish speleology as an independent academic subject. In contrast to earlier cave visitors, travelers began entering underground areas and attributing the names of “explorers” or “researchers” to themselves. Fieldwork—especially cave surveying and cartography—became common practice in speleology and such work provided important clues on speleogenesis, which was a controversial issue in the first half of the 20th century. Due to the fact that speleologists began separating themselves from ordinary …
Quantitative Hermeneutics: Counting Forestructures On A Path From W.M. Davis To The Concept Of Multiple-Permeability Karst Aquifers, H. L. Vacher, Lee J. Florea
Quantitative Hermeneutics: Counting Forestructures On A Path From W.M. Davis To The Concept Of Multiple-Permeability Karst Aquifers, H. L. Vacher, Lee J. Florea
International Journal of Speleology
Hermeneutics is the theory of interpretation. One of its major components is recognizing prejudgments, or forestructures, that we bring to our objects of study. In this paper, we construct a historical narrative of the evolution of thinking about the role of caves in relation to groundwater flow in limestone, and we tabulate forestructures as they appear in the story. This account consists of three overlapping time periods: the before and after of an incident that repelled hydrogeologists and students of karst from each other in the middle of the 20th century; a period, up to around the turn of …
Longitudinal Profile And Sediment Mobility As Geomorphic Tools To Interpret The History Of A Fluviokarst Stream System, John Woodside, Eric Wade Peterson, Toby Dogwiler
Longitudinal Profile And Sediment Mobility As Geomorphic Tools To Interpret The History Of A Fluviokarst Stream System, John Woodside, Eric Wade Peterson, Toby Dogwiler
International Journal of Speleology
The complex drainage systems within karst settings can result in atypical longitudinal profiles. Features, such as cave entrances, can be expressed as anomalous ‘bumps’ in the longitudinal profile of a stream if downcutting has continued upstream of the area in which the water is pirated to the subsurface. Horn Hollow, a fluviokarst valley located in Carter Caves State Park Resort in northeastern Kentucky, was examined for these types of features. The objectives of this study were to determine if sediment mobility can be used as a proxy for anomalous areas along the profile of the valley and if detailed cross-sections …
The Relationship Between Carbon Dioxide Concentration And Visitor Numbers In The Homothermic Zone Of The Balcarka Cave (Moravian Karst) During A Period Of Limited Ventilation, Marek Lang, Jiří Faimon, Camille Ek
The Relationship Between Carbon Dioxide Concentration And Visitor Numbers In The Homothermic Zone Of The Balcarka Cave (Moravian Karst) During A Period Of Limited Ventilation, Marek Lang, Jiří Faimon, Camille Ek
International Journal of Speleology
The evolution of CO2 levels with and without human presence was studied in a selected site (Gallery Chamber) of the homothermic zone of the Balcarka Cave (Moravian Karst, Czech Republic) during the fall, a period of limited ventilation. There were recognized various factors controlling the cave CO2 levels under different conditions in the exterior and interior. When visitors were absent, CO2 levels were controlled by the advective CO2 fluxes linked to cave airflows and reaching up to ~1.5x10-3 mol s-1. These fluxes exceed by orders of magnitude the exchanged diffusive fluxes (up to …

Karst Porosity Estimations From Archive Cave Surveys - Studies In The Buda Thermal Karst System (Hungary), Gáspár Albert, Magdolna Virág, Anita Erőss
International Journal of Speleology
The Buda Thermal Karst System is located under the densely populated hills of Budapest. One of its caves (Pál-völgy Cave System) is the longest cave of Hungary with 30.1 km. The research was done in this area as a methodological study to estimate karst porosity parameters of aquifers or hydrocarbon reservoirs. In this study two modeling methods are demonstrated. The volumetric modeling method was primarily aimed to determine the macro-scale (>0.5 m) conduit porosity (referred as macroporosity) of the study area as percentage of the incorporating limestone and marl. This method is based on archive survey data (maps and …
Comparing Flow-Through And Static Ice Cave Models For Shoshone Ice Cave, Kaj E. Williams, Christopher Mckay
Comparing Flow-Through And Static Ice Cave Models For Shoshone Ice Cave, Kaj E. Williams, Christopher Mckay
International Journal of Speleology
In this paper we suggest a new ice cave type: the “flow-through” ice cave. In a flow-through ice cave external winds blow into the cave and wet cave walls chill the incoming air to the wet-bulb temperature, thereby achieving extra cooling of the cave air. We have investigated an ice cave in Idaho, located in a lava tube that is reported to have airflow through porous wet end-walls and could therefore be a flow-through cave. We have instrumented the site and collected data for one year. In order to determine the actual ice cave type present at Shoshone, we have …
