The Aggitis karst system, Eastern Macedonia, Greece: Hydrologic functioning and development of the karst structure, , Novel Jean Paul, Dimadi Agoro, Zervopoulou Anna, Bakalowicz Michel,
SummaryThe Aggitis karst system developed in the marbles of the Rhodope massif. The conditions of the development of its karst drainage network are determined from the geological and geomorphologic settings by means of a microstructural analysis, following Eraso's method. This analysis shows that the karst conduit network intensely developed in the western part of the mountain Falakro where the majority of the open fractures oriented in the same direction as the hydraulic gradient, while the two directions are perpendicular in its eastern part drained by the spring of Drama.The behaviour of the system was analysed by means of hydrodynamic and water geochemical techniques. Despite the extension of the cave system and of the favourable development conditions of conduits, the functioning appears complex, with a significant storage, and a slow infiltration as well as an easy drainage. On the contrary the Drama karst system, characterised by a low variability in its hydrological and geochemical characteristics does not show any karst functioning.In the Aggitis karst system the initial groundwater flow conditions in combination with the aperture planes of which the directions are in agreement with the hydraulic gradient, favoured the rapid development of a drainage network system. The recharge from a large surface catchment area on non-karstic rocks, through swallow holes in a wide polje contributed to increase the groundwater flow through the karst part of the system, facilitating the development of the conduits

Morphology of New Zealand Limestone Caves , 1963, Laird, M. G.

Limestone caves in New Zealand can be divided into two distinct groups : those developed in the nearby flat-lying limestone of Oligocene age, and those formed in the strongly folded Mt. Arthur Marble of Upper Ordovician age. Caves formed in Oligocene limestone are typically horizontal in development, often having passages at several levels, and are frequently of considerable length. Those formed in Mt. Arthur Marble have mainly vertical development, some reaching a depth of several hundred feet. Previous research into the formation and geological history of New Zealand cave systems is discussed briefly, and the need for further work is emphasised.

Hydrology of autogenic percolation systems in some tropical karst outcrops, West Malaysia, 1983, Crowther J,
This paper reports on the flow regimes of underground seepages in three tower-karst outcrops and in the Setul Boundary Range, West Malaysia. Groundwater movement in the tower-karst hills, which comprise very pure, massive marbles, is confined to vertical and subvertical joints. Although flow is primarily diffuse and the discharges of the majority of seepages correlate most closely with rainfall in antecedent periods of 1-16 days or more, some stormflow occurs along conduits in the upper parts of these aquifers. Many of these conduits appear to peter out at depth into tight rock fractures, thereby forming funnel-shaped underground reservoirs which serve to moderate discharge variations. In contrast, the limestones of the Setul Boundary Range are less pure and retain much of their original bedding. The presence of near-horizontal bedding plane fractures favours lateral groundwater movement and the development of integrated drainage networks within the rock. Compared with the tower-karst caves, seepage rates are generally higher and more responsive to short-term variations in rainfall. The marked difference in topography between the tower-karst hills and the Setul Boundary Range is largely attributable to the contrasted geohydrological properties of the limestones

Forum : The Sedimentology and Palynology of some Postglacial deposits from Marble Arch Cave - Some Comments, 1988, Gale S. J. , Hunt C. O.

Upper Ordovician Arthur Marble and Oligocene Takaka Limestone contain extensive phreatic cave systems beneath the Takaka valley and Golden Bay. Half of all water flows in the Takaka valley pass through subterranean drainage conduits in carbonate rock. New Zealand's largest freshwater springs, the Waikoropupu Springs, are one surface expression of these karst systems. Other characteristics are dolines and submarine springs. A paleocave system developed in the Arthur Marble during the formation of the northwest Nelson peneplain in the Late Cretaceous and early Tertiary. Subsequent subsidence of the peneplain, and deposition of Motupipi Coal Measures, Takaka Limestone, and Tarakohe Mudstone, was followed by folding and faulting of the sequence in the Kaikoura Orogeny. Uplift and erosion in the Pleistocene brought the two carbonate rock formations within reach of groundwater movements. The paleocave system in Arthur Marble was reactivated during periods of glacial, low sea levels, and a smaller cave system formed in the overlying Takaka Limestone. Both systems interact and extend to more than 100 m below present sea level, forming the Arthur Marble - Takaka Limestone aquifer

A geological review of Abercrombie caves, 1991, Osborne, R. A. L.

Abercrombie caves (near Jenolan, N.S.W.) have developed in metamorphosed marble forming part of the Upper Silurian Kildrummie Formation. Geological structure and changes in lithology have strongly influenced cave development with pyritic thinly bedded units in the marble being preferentially eroded. The Abercrombie Arch originated as a through cave in Pliocene times, 4-5 millions years ago.

Biogenic weathering of marble monuments in Didim, Turkey in Trajan Column, Rome, 1993, Danin A.

Hydrochemical and hydrodynamical investigations are presented to explain tufa deposition rates along the flow path of the Huanglong Ravine, located in northwestern Sichuan province, China, on an altitude of about 3400 m asl. Due to outgassing of CO2 the mainly spring-fed stream exhibits, along a valley of 3.5 km, calcite precipitation rates up to a few mm/year. We have carried out in situ experiments to measure calcite deposition rates at rimstone dams, inside of pools and in the stream-bed. Simultaneously, the downstream evolution of water chemistry was investigated at nine locations with respect to Ca2 Mg2, Na, Cl-, SO42-, and alkalinity. Temperature, pH, and conductivity were measured in situ, while total hardness, Ca-T, and alkalinity have been determined immediately after sampling, performing standard titration methods. The water turned out to be of an almost pure Ca-Mg-HCO3 type. The degassing of CO2 causes high supersaturation with respect to calcite and due to calcite precipitation the Ca2 concentration decreases from 6 . 10(-3) mole/l upstream down to 2.5 . 10(-3) mole/l at the lower course. Small rectangular shaped tablets of pure marble were mounted under different flow regimes, i.e., at the dam sites with fast water flow as well as inside pools with still water. After the substrate samples had stayed in the water for a period of a few days, the deposition rates were measured by weight increase, up to several tens of milligrams. Although there were no differences in hydrochemistry, deposition rates in fast flowing water were higher by as much as a factor of four compared to still water, indicating a strong influence of hydrodynamics. While upstream rates amounted up to 5 mm/year, lower rates of about 1 mm/year were observed downstream. Inspection of the marble substrate surfaces by EDAX and SEM (scanning electron microscope) revealed authigeneously grown calcite crystals of about 10 mu m. Their shape and habit are indicative of a chemically controlled inorganic origin. By applying a mass transfer model for calcite precipitation taking into account the reaction rates at the surface given by Plummer et al. (1978), slow conversion of CO2 into H and HCO3-, and diffusional mass transport across a diffusion boundary layer, we have calculated the deposition rates from the hydrochemistry of the corresponding locations. The calculated rates agree within a factor of two with the experimental results. Our findings confirm former conclusions with respect to fast flow conditions: reasonable rates of calcite precipitation can be estimated in reducing the PWP-rate calculated from the chemical composition of the water by a factor of about ten, thus correcting for the influence of the diffusion boundary layer

Potential construction problems for bridge foundations in areas underlain by a complex marble formation in Hong Kong, 1995, Irfan T. Y. ,
Complex and varied geological conditions were encountered during the site investigation for a number of bridge foundations along the proposed route of a trunk road between two new towns in the North West New Territories of Hong Kong. Special care is needed in the construction of the deep foundations for these bridges, particularly in areas underlain by a marble formation which has a varied karstic surface underneath a thick superficial cover and locally contains solution features, includinglarge cavities. Foundation conditions are further complicated by varying lithology, weathering, dyke intrusions and the related alterations and thrust faulting

Karst Geomorphology and Hydrology of Gunung Tempurung, Perak, Malaysia, 1995, Gilleson David , Holland Ernst , Davies Gareth

Gunung Tempurung is a 600-metre high limestone tower in the Kinta Valley located to the south of the city of Ipoh, Malaysia. The tower contains at least one extensive cave system, Gua Tempurung, which has a length of approximately 4800 metres and a vertical range of about 200 metres. The tower is an erosional remnant of a thick sequence of Silurian - Permian Limestones initially formed as a shelf deposit near an ancient coastline. The carbonate rocks lie adjacent to, and are laterally bounded by, Late Mesozoic granite plutoniic rocks emplaced by activity related to the Late Triassic uplift from plate boundary stresses along the western edge of the Malay Peninsular. The limestones have been folded and compressed between the granites and have been altered by contact metamorphism to marbles and skarn. Hydrothermal mineralisation of the limestone host rock has yeilded deposits of tin, with some tungsten minerals and other minor ores. In the central part of the karst tower a river-cave system, Gua Tempurung, developed from local damming of the north and south outlets of a small catchment derived from the granite upland area to the east. In several locations inside the dry upper chambers of the cave, vein deposits of tin (cassiterite) are evident in walls and ceilings. Additionally alluvial tin deposits derived from the Old Alluvium are present in the cave.
