Tasmanian Cave Fauna: Character and Distribution, 1967, Goede, A.

The geology and nature of the caves is discussed. Cave development has been affected by glacial outwash and periglacial conditions which must be taken into account when considering the development and distribution of cave fauna. The food supply in the caves is limited by the absence of cave-inhabiting bats. Floods while adding to the food supply must be destructive to some forms of terrestrial cave life. The cave fauna consists entirely of invertebrates. The carab genus Idacarabus Lea contains the only troglobites found in Tasmania. A common troglophile throughout the island is Hickmania troglodytes (Higgins and Petterd) which belongs to a very small group of relict spiders. Five species of cave crickets are known from Tasmania and Flinders Island. Three species belong to the genus Micropathus Richards and show an interesting distribution pattern. A single species of glow-worm, Arachnocampa (Arachnocampa) tasmaniensis Ferguson occurs in a number of Tasmanian caves. It is more closely related to the New Zealand species than to glow worms found on the Australian mainland. Other terrestrial cave life is briefly discussed. Aquatic cave life is poorly known. The syncarid Anaspides tasmaniae (Thomson) has been recorded from several caves. It differs from epigean forms in reduction of pigment.

THE PART OF THE QUATERNARY INHERITED FEATURES IN THE ALPINE KARSTS: THE EXAMPLE OF THE SOUTHERN ALPS - The periglacial past-processes influenced karst landforms. 1) the paleoclimatical change (Wrm) related to the present climatical parameters; 2) the impact of periglacial processes on the superficial karst; 3) the internal evolution of the karst during the cold phases.

Un karst subalpin mditerranen : la rgion Audibergue-Mons (Alpes-Maritimes et Var), 1984, Julian M. , Nicod J.
THE KARSTIC AREA AUDIBERGUE-MONS (Prealps of Grasse, Maritime Alps and Var departments) - This area, very important for the karstic superficial features and the caves, is formed by the proximity of plateaus belonging to the structural system of Provence and the higher main subalpine unit of Audibergue. Three fields of sinkholes are especially characteristic: 1/ central Audibergue, controlled by shear fractures and under the influence of nival phenomena; 2/ Fort d'Esclapon, with more various forms and perhaps an older karstic evolution that explains the large inheritance of terra rossa; 3/ Biron that shows deep furrows and sinkholes. The study of the poljes, fluvio-karstic (Caille) or half-opened (Canaux), introduces the problem of the underground karstic hydrology. The dynamics of neotectonics and morphoclimatic systems, specially the old periglacial processes, is considered with reference to the main forms and deposits shown on the map.

Les massifs karstiques des Alpes occidentales, trame structurale et bioclimatique, 1984, Nicod, J.
THE KARSTIC MASSIFS OF WESTERN ALPS: structural and bioclimatic framework - The structural conditions determine several types of karst units: the northern Prealps (thrusts), the southern Jura (folded or tabular), the southern Prealps (faulted and folded plateaus), the complex land of Low Provence, and the high karsts of Inner Alps. The bioclimatic framework explains the altitudinal sequence of current processes. The value of the runoff, the part of the snow, and the biochemical parameters (vegetation, CO2), have particularly holded the attention. The specific dissolution reaches its maximum in the wooded mountain karsts. Heritages also determine the landforms (glacial, periglacial, terra-rossa).

Quaternary engineering geology, 1991, Fookes Pg,
The geological and geomorphological effects on the Earth's surface during the Quaternary have been both extensive and profound. An attempt has been made to simplify and summarize these effects by considering the principal agencies at work during the Quaternary: plate tectonics, rapidly rising sea levels, rapidly falling sea levels, rapidly cooling climates and rapidly warming climates. The resulting series of major glacial and interglacial episodes have had far-reaching consequences for the engineering characteristics of the Earth's surface. In attempting to summarize these major omissions will have been inevitable and errors will have occurred due to compression of the subject and its interpretation in a simplified manner. Table 2 summarizes the approach of the paper in itemising the principal Quaternary events, causes and effects, consequences to landscape and inferences to engineering. Each of the six events has been developed into larger tables and accompanied by some discussion and examples. The principal consequences of the events for engineering have been the production of glacial and periglacial soils,over large areas of the northern and southern hemispheres; changes in the sediment patterns on the coasts, the continental shelves and in river systems; and the development of weathering profiles of very variable type and distribution leading to development of in situ residual soils of many different engineering characteristics. The major shifts in climate associated with these events have led to migration of various surface forms which are now being exposed or covered by the present regime, leading to many active slope processes with potential instability for engineering projects and unexpected distribution of materials. The continuing events of plate tectonics which precedes the Quaternary by a long period of geological time explain the distribution of earthquake systems, growing coastlines and mountains, and the pattern of volcanic areas with their own suites of rock and soil of significance for the engineer. ...

Signification des remplissages des karsts de montagne, quelques cls lusage des splologues, 1995, Audra, P.
This paper is intended to cavers in order to help them identify the most significant mountain karst infillings. Carbonated varves sedimentation occurs during floodings in glacial environment. The varves block the deep parts of the networks. Pebbles sealings show a powerful erosion in the vadose zone, near glacial sinkholes. Gelifract spreadings are indicators of frost and snow action in periglacial environment. Reworked weathered rocks are the most ancient deposits, inherited from tertiary warm phases when karstification occurred under regolith covers. Their clearing is partly simultaneous with cave systems elaboration, in relation to the alpine uplift, during Pliocene. Speleothems are also warm or temperate climate indicators. Crystalline morphology reflects environmental characteristics, while their surface sight could have been smoothed during discharge reactivations. Finally, some infillings could have recorded neotectonic movements: broken speleothems, deformed clastic sediments, etc.

Observations sur le karst de Bardas Blancas-Malarge (Andes de Mendoza, Argentine), 1995, Mikkan, R. A.
The karst of Bardas Blancas, situated south of Mendoza province, deve-lops in Jurassic and Cretaceous limes-tones. The continental and semi-arid climate (300 mm/year) is characterized by temperate summers and cold winters. The periglacial processes are actives. The relief presents a semi-karstic morphology: structural landforms ("Schichttreppenkarst" with cuestas) and afew dolines, swallow-holes and pavements. The Los Brujas cave, about 1 000 m long, shows a labyrinthic network (3 siaged levels) with phreatic passages. The impor-tant gypsum speleothems (crusts, flowers) in the lower level and the calcite-opale speleothems indicate an hydrothermal speleogenesis (dissolution by sulfuric acid and gypsum deposit). The actual and active tectogenesis of this region (uphft, hydrothermalism, volcanism) plays an important part in the geomorphological evolution.

A morphological analysis of Tibetan limestone pinnacles: Are they remnants of tropical karst towers and cones?, 1996, Zhang D. A. ,
Limestone pinnacles on mountain slopes in Tibet were measured for morphological analysis and the results were compared with those from tropical towers and cones on karst mountain slopes of Shuicheng, southwest China. In the form analyses, the symmetric products (P) of Tibetan pinnacles present large differences between individual pinnacles. The plan forms, represented by long/short axes ratios (R(L/S)), are mostly irregular and scattered and the diameter/height ratios (R(dfh)) reveal that the Tibetan I features could belong to any three cone or tower karat types, according to Balaze's classification of karst towers. The direction of pinnacle development seems to be primarily related to slope aspect and to geological structure. The morphological structure and orientation analyses show that pinnacle development is largely controlled by lithological and stratigraphic conditions. The closed water catchment structure, which is a basic feature in karat areas, has not been found in the limestone pinnacle areas of Tibet. The results of the form and structure analyses for the Tibetan pinnacles differ from those for tropical and subtropical karst areas. Further analysis indicates that Tibetan limestone pinnacles were formed by strong physical weathering under periglacial conditions. Four kinds of morphogenesis of the pinnacles are suggested

Aufeis of the Firth River basin, Northern Yukon Canada: Insights into permafrost hydrogeology and Karst, 1997, Clark Id, Lauriol B,
The 31-km(2) aufeis ice sheet of the upper Firth River holds a wealth of information on groundwater hydrology in periglacial environments. Baseflow recession calculations, corrected for aufeis storage (12% of basin discharge), indicate specific groundwater recharge rates of up to 100 mm yr(-1) (up to 50% of runoff), suggesting a significant proportion of drainage from karst. The upper Firth River aufeis is a composite aufeis, with discrete baseflow contributions from different watersheds. Since the late Pleistocene, annual growth of the aufeis has exerted a strong control on lateral erosion and the local river channel geomorphology. Two groundwater recharge processes are distinguished on the basis of carbonate geochemistry and 8(13)C: (1) Methanogenic groundwaters, with C-13(DIC) up to -3.3 parts per thousand, are recharged through saturated soils underlain by permafrost; conditions which support anaerobic consumption of dissolved organic carbon (DOC) and produce up to 700 mu g-CH4 L-1 (calculated), and (2) Karst groundwaters, with C-13-depleted DIC, recharged through unsaturated soils and circulate through fissured talik in the carbonate bedrock. Most drainage from the region shows varying contributions of these two groundwaters, although a greater contribution from the methanogenic groundwaters occurs in north-facing watersheds. The 8(13)C values far cryogenic calcite precipitates in the ice indicate that the karst groundwaters are the major contribution to aufeis growth. The combined use of 8(13)C(DIC) and geochemistry may be a useful tool to quantify methanogenesis in northern watersheds

Contemporary karst solution processes on the Tibetan Plateau, 1997, Zhang D. ,
The Tibetan Plateau, with an average elevation of 4,000-5,000 m a.s.l., is cold and arid, and geomorphologic processes are dominated by periglacial, glacial, and aeolian agents. Here, the highest known, currently-developing karst features were found during the Sino-British Expedition of 1987. Measurements of CO2 partial pressure were taken in air, soil, sediments, and caves. Also measured were the solubility of Tibetan limestones, the dissolved CaCO3 in water, and the electrical conductivity of karst waters. Field solution experiments show that CO2 partial pressure is one of the lowest in the world. Dissolved limestone content in fresh karst water is lower than in other karst areas. The solubility of the major Tibetan limestones varies little, but field experiments indicate that karst solution rates are affected by geomorphologic and climatic conditions. The formation and distribution of the present-day karst features correspond with the results of field and laboratory solution experiments. They are mainly small surface features in relatively wet and warm locations, especially where soil is in direct contact with limestone. Measurements of solution rates and CO2 content indicate that biologically stimulated solution plays an important role in karst development on this cold and arid plateau

Rapport entre karst et glaciers durant les glaciations dans les valles pralpines du sud des Alpes, 1998, Bini Alfredo, Tognini Paola, Zuccoli Luisa
At least 13 glaciations occurred during the last 2.6Ma in the Southern pre_alpine valleys. The glaciers scouring alpine and pre-alpine valleys had all the same feature, being valley temperated glaciers. Their tracks and feeding areas were always the same, just like the petrological contents of their deposits. Contrary to previous assumptions until a few years ago, the origin of these valleys and of the lakes occupying the floor of some of them (Orta, Maggiore, Como, Iseo, Garda Lakes) is due to fluvial erosion related to Messinian marine regression. The valley slopes modelling is Messinian in age, too, while most caves are older. As a general rule, glaciers worked on valley slopes just as a re_modelling agent, while their effects were greater on valley floors. The karstic evolution began as soon as the area was lifted above sea level (upper Oligocene - lower Miocene), in a palaeogeographical environment quite different from the present one, although the main valley floors were already working as a base level. During Messinian age, the excavation of deep canyons along pre-existing valleys caused a dramatic lowering of the base level, followed by a complete re-arrangement of the karstic networks, which got deeper and deeper. The Pliocene marine transgression caused a new re-arrangement, the karst network getting mostly drowned under sea level. During these periods, the climate was hot-wet tropical, characterised by a great amount of water circulating during the wet season. At the same time tectonic upliftings were at work, causing breaking up of the karst networks and a continuous rearrangement of the underground drainage system. In any case, karstic networks were already well developed long before the beginning of Plio-Quaternary glaciations. During glaciations, karst systems in pre-alpine valleys could have been submitted to different drainage conditions, being: a) isolated, without any glacial water flowing; b) flooded, connected to the glacier water-filled zone; c) active, scoured by a stream sinking at glacier sides or in a sub glacial position. The stream could flow to the flooded zone (b), or scour all the unflooded system long down to the resurgence zone, the latter being generally located in a sub glacier position. The glacier/karst system is a very dynamic one: it could get active, flooded or isolated depending on endo- and sub-glacial drainage variations. Furthermore, glaciers show different influences on karstic networks, thus working with a different effect during their advance, fluctuations, covering and recession phases. Many authors believe, or believed, the development of most surface and underground karst in the Alps is due to glaciations, with the last one held to be mostly responsible for this. Whatever the role of glaciers on karstic systems, in pre-alpine valleys caves, we do not have evidence either of development of new caves or of remarkable changes in their features during glaciations. It is of course possible some pits or galleries could have developed during Plio-Quaternary glaciations, but as a general rule glaciers do not seem to have affected karstic systems in the Southern pre-alpine valleys with any remarkable speleogenetic effects: the glaciers effects on them is generally restricted to the transport of great amounts of debris and sediments into caves. The spotting of boulders and pebbles trapped between roof stalactites shows that several phases of in- and out-filling of galleries occurred with no remarkable changing in pre-dating features, including cave decorations. The presence of suspended karst systems does not prove a glacial origin of the valleys, since most of them pre-date any Plio-Quaternary glaciation, as shown by calcite cave deposits older than 1,5Ma. The sediments driven into caves might have caused a partial or total occlusion of most galleries, with a remarkable re-arrangement of the underground drainage system. In caves submitted to periglacial conditions all glaciations long, we can find deposits coming from weathered surface sediments, sharp-edged gelifraction debris and, more rarely, alluvial deposits whose origin is not related to the circulation of the glacial meltwater. In caves lower than or close to the glaciers limit we generally find large amounts of glacier-related deposits, often partly or totally occluding cave galleries. These sediments may be directly related to glaciers, i.e. carried into caves by glacial meltwaters, resulting from surface glacial deposit erosion. They generally show 3 dominant facies: A) lacustrine deposits; B) alluvial deposits and C) debris flow deposits facies. The only way of testing the soundness of the forementioned hypothesis is to study the main characters and spreading of cave sediments, since they are the only real data on connection of glaciers to endokarst networks.
