Present-Day Cave Beetle Fauna in Australia A Pointer to Past Climatic Change, 1965, Moore, B. P.

Beetles form an important element of life in caves, where they provide some of the most spectacular examples of adaptation to the environment. The troglobic forms are of greatest interest from the zoogeographical point of view and their present distributions, which are largely limited to the temperate regions of the world, appear to have been determined by the glaciations and later climatic changes of the Quaternary. Troglophiles, which are much more widespread, show little adaptation and are almost certainly recently evolved cavernicoles.

Cockroaches (Blattodea) From Australian Caves, 1967, Richards, Aola M.

Ten species of Australian cockroaches are recorded from Australian caves and mines. Most are troglophiles or guanobia. Only one troglobitic species is known. The distribution of these species is given, and attention is drawn to their absence from south-eastern Australia and Tasmania. It is suggested that climatic changes in the Pleistocene and early Recent may have been responsible for this, and that the fauna found in many cave areas may be of comparatively recent origin.

Messinian event in the black sea, 1979, Hsu Kenneth J. , Giovanoli Federico,
Three holes were drilled during the 1975 DSDP Leg 42B drilling the Black Sea. A section from Hole 380, at 2107 m water depth on the western edge of the abyssal plain, is 1074 m thick, and provides the most complete stratigraphic section. Dating of the sediments is based upon (1) fossil evidence from pollen, crustaceans, benthic foraminifera, and diatoms, (2) correlation with climatic changes and with unusual isochronous events that have been dated elsewhere, (3) paleomagnetic data, and (4) estimates of sedimentation rate.The history of Black Sea sedimentation recorded by the DSDP cores includes black shale sedimentation during the Late Miocene, followed by periodic chemical sedimentation from Late Miocene to Early Quaternary, and a change to dominantly terrigenous sedimentation from the Middle Quaternary. These hemipelagic and turbiditic sediments were deposited in lacustrine and brackish marine environments. The Messinian sediments, however, consist of stromatolitic dolomite, oolitic sands, and coarse gravels, deposited in supratidal and intertidal environments. The intercalation of the shallow-water sediments in a deep-water sequence suggests a drastic lowering of the water-level within the Black Sea basin during the Messinian so that the edge of the present abyssal plain was then the edge of a shallow lake.The Messinian draw-down phase of the Black Sea was in existence for about 100,000 years during the Lago-Mare stage of the salinity crisis. The evaporated waters formed an alkaline lake before it was drowned by a brackish marine transgression correlative to the Trubi transgression of the Mediterranean

Une morphologie karstique typique en zone intertropicale : les karsts du Bas Zare, 1985, Quinif, Y.
A TYPICAL MORPHOLOGY OF TROPICAL KARSTS: THE KWILU BASIN IN THE LOWER-ZAIRE - The Kwilu basin, in the region of Bas-Zaire, shows typical landscapes of tropical karsts: cone and tower karsts shaped in precambrian limestones of the "Groupe schisto-calcaire". These precambrian series are little tectonised. They are covered with cenozoic formations which are important in the evolution of the karst. Different types of cavities are studied and replaced in the morphostructural context: old caves, originating in phreatic zone and now cut by the erosion, river streams in tunnel-caves, network under the water table. The superficial forms are interpreted as successive evolutive steps: dissection of a surface (morphological or structural) by a dendritic hydrographic network, birth of a cone-karst being transformed in tower-karst overlooking a new surface. We insist on the morphogenetic importance of the paleoclimatic changes and on the existence of an intertropical karstic morphology in stable craton.

Quelques aspects du karst en Chine, 1985, Tricart, J.
Some characteristic features of karst in China Karst terrain is widespread in China: some 2,000,000km2, corresponding to 20-25% of the whole surface of the country. It occurs at very different altitudes and under quite different climates, from the region of Zhoukoudian, where has been found the skull of the Pekin Man, to the Tibet Plateau, where there is presently permafrost conditions, and up to southern tropical moist China, near Canton and Guilin. Recent chinese investigations have proved that most karst features are old. In Southern China a tropical karst (tower-karst or "mogotes" karst) is associated with lacustrine deposits containing the well-known Hipparion Fauna, of Miocene age. Its predates the intensive uplift of the Himalaya and of the Tibet, which has begun during the Pliocene and has continued during all the Pleistocene. The same fossils have been found in this tropical karst in present permafrost areas, above 5,000m. In the region of Guilin (Guangxi Province), this tropical karst has been described. There is evidence for the former existence of a covered karst, where limestones and dolomitic limestones were covered by a thick layer of reddish residual clays, with limonite. This mantle has been stripped during different periods of drier and probably cooler climate, has suggested by pollen spectra. In some places, these residual products have been trapped into pits, cracks, and caves. We have observed a small quantity of red clay painting limestone stalactites and sinters (Chuanshan and Leng Yin Yen Caves, in the surroundings of Guilin). They present sometimes a mining interest and some extractive industries are presently active (limonite, cassierite, etc.). Many caves have been surveyed by the Institute of Karst geology, in Guilin. Some have been equiped for tourism, around Guilin. All these caves are old. Some radiocarbon dating of speleothems yield ages of 33,000 year BP. The famous carving of the Leng Yen Cave have not been affected by calcite deposition from dripping since at least 500 years. The large caves that have been surveyed should correspond to a long evolution span. Along the Lijiang River, at least two terraces can be observed. They are built with gravels and pebbles, covered with thinner sand and loam, suggesting climatic changes, also attested by the changes of fauna and vegetation. These past cooler periods are characterised by an opened vegetation, with the striping of the old weathering cover of the former tropical karst. These karst terrains have been investigated in China for management purposes. Groundwater oscillations have frequently resulted in land subsidences damaging buildings, and in dramatic collapses destroying fields, roads. Sometimes, underground collapse plugged caves and dammed underground rivers, resulting in floodings. The caves are frequently used as reservoirs for irrigation and power plants.

Observations morphologiques sur le gosystme karstique du Rupt du Puits (Meuse, Lorraine), 1995, Jaillet S. , Gamez P.
The karst system of Rupt-du-Puits is situated east of the Paris basin (Barrois and Perthois), in the Portlandian limestones covered by sands and clays of Lower Cretaceous. It presents 21 km of surveyed passages in several networks (catchment = 13 km2). In this typical covered karst (cryptokarst), we observe two kinds of alimentation: rapid (swallow holes) and slow (wet soils). On the exokarst, the valleys move by retreat of swallow holes and karst stepping. In the endokarst, the variations of the base level determine several stages of stream piracy (elbows of capture). The karst morphology depends on climatic changes and the evolution of the drainage pattern during the Upper Pleistocene.

Signification chrono-climatique de splothmes lamins de Chine du nord, 1998, Ming Tan, Tungsheng Liu, Xiaoguang Qin, Xianfeng Wang
Speleothems from North China show that many of them have very fine microlayer growth. Most of these layers have bi-optical characters that can be observed under fluorescent and transmitted light. Hydrological analysis and radio-isotopic dating demonstrate that those layers are annually laminated. A Holocene stalagmite from Shihua Cave in Southwest Beijing presents thousands of micro-layers which are very similar to tree rings. Based on the measurements of the thickness of annual layers, short-term climatic changes over the last 1,130 years in the Beijing area are discussed.

A mineralogical analysis of karst sediments and its implications to the middle-late Pleistocene climatic changes on the Tibetan Plateau, 1998, Zhang D. D. ,
The minerals in various categories of Tibetan karst sediments were divided into three groups: carbonate, iron and silicate. The carbonate minerals, including calcite, aragonite and dolomite, consist mainly of speleothem, tufa and sinter. Most of the speleothems indicates wetter and warmer periods in early and middle Pleistocene, the youngest being 194,000 years old. The second formation of carbonate mineral, tufa, implies an arid period starting 91,000 years BP. The iron minerals, goethite and hematite, are often mixed up with cave alluvial sediments that are interbedded with flowstones, and the depression sediments. They indicate strong oxidizing environments during their deposition, which is absent at present. The clay minerals, specially kaolinite, were contained in cave alluvial, flowstone and the depression sediments as well. Combined with stratigraphic study and U-series dating, the mineral analysis shows that warmer and wetter climates, which were suitable for speleothem development, probably disappeared 200 ka ago, and drier and colder climates dominated this plateau since then

Spectral analysis of a 1000-year stalagmite lamina-thickness record from Shihua Cavern, Beijing, China, and its climatic significance, 1999, Qin Xiaoguang, Tan Ming, Liu Tungsheng, Wang Xianfeng, Li Tieying, Lu Jinpo,
Stalagmite laminae provide a high-resolution geological record of climate change. In this paper, moving spectral analysis is used to analyse a stalagmite lamina thickness record to study climatic variability. It was found that the dominant cycles of the lamina thickness sequence are 2, 3.3, 5-6, 10-12, 14-18, 133 and 194 years. Some of the cycles are the same as the cycles of modern climatic indices, such as the QBO (Quasi Biennial Oscillation) of 2 years, the QTO (Quasi Triple-year Oscillation) cycle of about 3.5 years, the QFO (Quasi Five-year Oscillation) cycle of 5-6 years and the QEO (Quasi Eleven-year Oscillation) cycle of 11 years. It was also found that there are different dominant cycles in different time periods. Usually, the dominant cycles are stronger in wet periods when the microlaminae are thicker. In dry periods, the microlaminae are thinner and the power of the dominant cycles is also weaker. Another feature is that the power of the dominant cycles and their long-term periods and frequencies appear to change. These phenomena are important for understanding the climatic changes in Beijing area over the last 1 ka

Paleokarst features and other climatic relics in Hungarian caves, 1999, Bolnertaká, Cs Katalin

Relics of climatic changes during the modern phase of karstic development have been preserved in the morphology, sediments and speleothems of several caves in Hungary; and there are examples of real paleokarst features exposed by modern caves as well. The unique sandstone morphology of Cserszegtomaj Well Cave (Keszthely Mts., Transdanubian Mountain Range), developed along the contact of Triassic dolomite and Pannonian sandstone, displays the relief of a karst surface formed probably under the subtropical conditions of the Early Miocene. The uppermost parts of Beremend Crystal Cave (Villány Mts., South Transdanubia) exposes also from below the clastic fill of an ancient karst shaft that, according to its rich vertebrate remains, dates back at least to the Lower Pleistocene. With their Late Eocene marine sediment fill, the small paleokarst cavities exposed in the Eocene bedrock of Mátyás-hegy and Pál-völgy Caves (Buda Hills) are interpreted as salt-fresh water mixing zone cavities formed during a short immersion of a tropical reef.

Role of mixing corrosion in calcite-aggressive H2O-CO2-CaCO3 solutions in the early evolution of karst aquifers in limestone, 2000, Gabrovsek F, Dreybrodt W,
Two cave-forming mechanisms in limestone are discussed currently. First, when two H2O-CO2-CaCO3 solutions, saturated with respect to calcite but with different chemical compositions mix, renewed aggressiveness to limestone dissolution occurs. This process called mixing corrosion [Bogli, 1964, 1980], in combination with linear dissolution kinetics, has been suggested as cave forming. Second, it has been shown that solely the action of nonlinear dissolution kinetics can generate extended karst conduits. This paper combines both mechanisms. By digital modeling of the evolution of the aperture widths of a confluence of two fractures into a third one it is shown that the first mechanism does not create large cave conduits. The combination of mixing corrosion and nonlinear kinetics, however, considerably intensifies karstification, compared to that of nonlinear kinetics solely. The times to terminate early evolution of karst are significantly reduced when the CO2 concentrations of the inflowing solutions differ by no more than 30%. We discuss the underlying mechanisms by inspection of the time dependence of the evolution of aperture widths, flow rates through them, and of the renewed undersaturation of the mixed solution at the confluence of two fractures. Finally, the evolution of a karst aquifer on a two-dimensional percolation network is modeled when mixing corrosion is present, and compared to that on an identical net with identical nonlinear dissolution kinetics, but mixing corrosion excluded. Large differences in the morphology of the net of cave conduits are found and also a reduction of the time of their evolution. From these findings we conclude that climatic changes, which influence the p(CO2) in the soil, can divert the evolving cave patterns

Etude du fonctionnement dune cavit englace durant un cycle climatique : site de la glacire dAutrans (Vercors), premiers rsultats, 2001, Perroux, Annesophie
This underground ice work comes in the framework of high-resolution environmental records in underground deposits researches. With this aim, we have chosen the Autrans ice cave to analyse an ice core. In a preliminary research about the ice cave and its working in comparison to climatic variations, we have two informations: there's two types of working, of dynamic from season to season, and the cave morphology is very important for draughts.

Karst lakes of the Protected Landscape Area - Biosphere Reserve Slovensky kras karst and Aggtelek National Park, 2001, Barancok P,
In the extent karst area belonging to the Protected Landscape Area - Biosphere Reserve Slovensky kras karst and Aggtelck National Park arc several lakes. They arc very significant biotopes. At present they arc extincted rapidly, their water surface is reduced, they are silted relatively quickly and they arc overgrown by wetland vegetation. In order to clarify the causes of their extinction the development of 3 takes of the area Slovensky kras karst - lakes Jastericicic jazero lake, Smradrave jazierko lake and Fardrova jama lake and 3 lakes of the area Aggtelck Karst - lakes Aggtelcki-to, voros-to and Kardos-to were evaluated. From the area Slovensky kras karst are well known 2 further lakes - Lucanske jazierko lake and Cierne jazero lake. Climatic changes and prevailingly negative impact of man have decisive influence on the development of all lakes in the mentioned area

Failure of an industrial wastewater lagoon in a karst terrain and remedial action, 2001, Memon B. A. , Azmeh M. M. ,
Failure of a wastewater lagoon, caused by development of a sinkhole underneath the lagoon at a site in the Lehigh River Valley near Allentown, Pennsylvania, allowed waste water to enter into the underlying karstified carbonate aquifer, a source of public water supply in the area. Identification of the contamination and development of an appropriate site-specific remediation plan required understanding of site geology, stratigraphy, hydrogeologic setting and aquifer characteristics. Information on site geology and hydrogeology, including aquifer geometry and matrix, occurrence and flow of groundwater were collected and evaluated. Core holes were drilled, geophysically logged, and correlated to define stratigraphy and structural controls to the movement of groundwater and pollutants. Monitoring wells were installed. Water level data collected on a continuous basis were used to determine the direction and gradient and also correlated with climatic changes to define amplitude of fluctuations of groundwater. Correlation of lithologic logs and interpretation of geophysical logs identified five water-producing zones separated by semi-confined layers within the carbonate aquifer. Water samples were collected from different water producing zones and analyzed to delineate vertical and horizontal extent of contamination. Pentaerythritol (PE), which was directly linked with the failure of lagoon, was identified as a pollutant in groundwater. PE was found to be present in the lower water-producing zones. Based on a geologic and hydrogeologic model of the site and understanding of flow regime and presence of PE in the lower water producing zones, a remedial plan (a pump-and-treat system) was developed and implemented to remediate the aquifer. This remedial action has reduced the PE level in groundwater and also created a pressure trough as a barrier to off-site migration
