The study area is situated within the complex structure and karst system of the western Taurids. Basinwide interpretation of the structural features, each of which has great importance, will enlighten many complicated hydrogeologic problems encountered in the area. Thus, considering the previous views on the structural geology of the area, an interpretation of the structural and tectonic features of the study area by means of satellite images was undertaken, and based on the data gained, new approaches were suggested to solve the hydrogeological problems, in particular, determination of the recharge-discharge mechanisms of the Olukkopru and Dumanli karst springs, which are the most important karst groundwater discharge points in the region, has been attempted. Within the framework of this study, a tectonic-lineament map of a large area covering Eqirdir, Beysehir, and Sugla lakes at the north and the basins to the south of these lakes was prepared

Geological and hydrogeological remote sensing techniques can be applied very favorably to Dinaric karst in the Balkans, a well-known reference area for studies of karst phenomena. The elements that make karst terrain of the Dinarides suitable for remote sensing are geomorphologic characteristics, in particular the specific surface drainage and karst forms, the varying vegetation that most often reflects the existence of different geologic formations on the surface, and distinct tectonic features. Some of the world's largest springs, ponors (sinks), and dolines are controlled by fractures visible on both satellite images and aerial photographs. Lineaments represent fault zones, systems of close faults with similar strike, or large individual faults which all are young or show recently renewed activity. Their neotectonic character and major importance for karst groundwater flow are confirmed by numerous field investigations including water tracing, geophysical research, and drilling

Structure of northern Mount Sedom salt diapir (Israel) from cave evidence and surface morphology, 1996, Frumkin, A.

Mount Sedom salt diapir, at the south-western edge of the Dead Sea, is covered by a residual caprock, concealing its internal structure. Internal structure observed within karstic caves is correlated here to surface lineaments on top of the caprock. The structural evidence suggests that the northern part of the diapir consists of two salt walls rising from the east and the west. The border between the two walls is observed in caves along the northwestern part of the mountain. The layers are highly deformed along this border, while on both limbs the beds are relatively undeformed, dipping in different directions. The eastern limb comprises most of the width of the elongated northern part of the diapir.

The Eastern boundary of the giant karst of Vaucluse in relation to the lineament-fault of Aix-en-Provence (Provence, Alps, Cote d'Azur Region, France), 1997, Rousset C. ,
In the Saint-Donat area, along the Mardaric stream, a tributary of the mid Durance, water losses associated with temporary springs can be observed. These springs run off overflows of the Vaucluse karstic system. Their impluvium extends over the limestones of the eastern part of the Montagne de Lure; this karstic area contributes, with the runoff entering into the losses, to the underground flows of the Fontaine de Vaucluse. As it rose eastwards, the drainage network of this giant karst was halted by the faults of the Aix-en-Provence lineament, in which very strongly deepening marls form a barrier around the aquifer. This is new evidence of the part played by the Hercynian-inherited lineament framework in limiting giant karsts of the Vaucluse-type, as is the case for the Alpine carbonate platforms in which they have developed

Gypsum karstification in the Middle Miocene Fatha Formation, Mosul area, northern Iraq, 1997, Jassim Saad Z. , Jibril Antwanet S. , Numan Nazar M. S. ,
Karstified Middle Miocene sediments are widely exposed in northern Iraq particularly in the area surrounding the city of Mosul. The unit is dominated by gypsum and exposed in thirteen anticlinal structures within the investigated area of about 1600 square kilometers. Synclines, though containing the same sequence, are not karstified due to a Quaternary cover. Karst features were located from air photos: Over 4000 were recorded, the smallest detectable being two meters in diameter. The majority are sinkholes (dolines), developed in gypsum and manifested in the overlying collapsing limestone. They are singular, in lines or clusters. Shafts and karren are fewer in number and are usually developed in uncovered gypsum. Sinkholes are visibly located along fractures and at fracture intersections over gently inclined limestone beds overlying the gypsum. Two karst systems were identified, an active and recent system characteristic of all the anticlinal structures and an older (Pleistocene) fossil karst system characteristic of Alan, Ishkaft, Albu Saif and Hammam structures. The fossil karst system is preserved on remnant elevated old land surfaces and produces characteristic tight undulations in the limestone due to collapse inwards in sinkholes and elongated tunnels formed along a series of sinkholes. The fracture study of anticlinal structures reveals that the mean fracture density per area ranges between 4 and 8 (km/km2) and shows a unimodal character for most of the structures. However the distribution of karst in relation to fractures is bimodal for at least half of the structures with mean values ranging from 4.5 to 11 (km/km2). The fractures in the anticlines are thought to have formed due to folding but some are associated with major lineaments cross cutting the structures, which is reflected in the bimodality and the crude unimodal fracture/karst distribution. Karst features are related to the general fracture pattern but are more localized in densely fractured areas. Karst areas were also found to correlate with lower slope gradient and lower drainage density

Karst terraines in Iran - Examples from Lorestan, 1999, Ahmadipour, Mohammad Reza

In Iran karst terrain covers about 13% of the total area. The carbonate rocks belong to the Eocene, Oligocene-Miocene, Miocene, Jurassic and Cretaceous. Most of the carbonate rocks are developed in the basins of Mazindaran and Zagros. The carbonate rocks in the Zone of Zagros, due to the prevailing tectonic activities, have undergone more processes of karstification. About 56 % of all the springs originated from this zone. In Lorestan the Zagros zone consists of a series of parallel anticlines in which, due to the tectonic movements, the rocks have undergone folding and fracturing. The folding and fracturing have created rich ground water reservoirs. The carbonate rocks of Lorestan show all types of karst features such as karren, dolines and caves. The most developed karstic features are seen in the Bangeston group. Most of the springs are discharged either along the lineaments or at the intersection of the lineaments. The chemical analyses of the samples show that they are of bicarbonate type. The drinking water of the city of Khorramabad (capital of Lorestan) is supplied from the karstic springs. In this paper, the karst hydrology of two important regions of Lorestan are considered.

Hydrotermalni puvod jeskyni v Ceskem krasu: nove paradigma, 1999, Suchy V. , Zeman A.

The caves developed in Lower Paleozoic carbonate rocks of the Bohemian Karst are interpreted as a result of a hydrothermal dissolution. The main evidence includes 1) a close spatial link of the caves to hydrothermal calcite veins, 2) a variety of distinctive dissolution forms indicative of non-gravitational hydrodynamics, and 3) presence of specific, exotic precipitates within the caves. Moreover, most of the features typical of the caves of the Bohemian Karst can be readily compared to those of the Zbrasov Caves of Moravia that have been known for long as a typical example of hydrothermal caves. The origin of at least some hydrothermal caves in the Bohemian Karst and elsewhere in the Czech Republic could have been tied to the circulation of warm fluids along active tectonic lineaments. A line of indirect evidence indicates that in the Bohemian Massif, transient pulses of fluid activity that were responsible for the origin of hydrothermal caves may have occurred since Tertiary period.

Geochemical study of calcite veins in the Silurian and Devonian of the Barrandian Basin (Czech Republic): evidence for widespread post-Variscan fluid flow in the central part of the Bohemian Massif, 2000, Suchy V. , Heijlen W. , Sykorova I. , Muchez Ph. , Dobes P. , Hladikova J. , Jackova I. , Safanda J. , Zeman A.

Carbonate fracture cements in limestones have been investigated by fluid inclusion and stable isotope analysis to provide insight into fluid evolution and deformation conditions of the Barrandian Basin (Silurian–Devonian) of the Czech Republic. The fractures strike generally north–south and appear to postdate major Variscan deformation. The most common fracture cement is calcite that is locally accompanied by quartz, natural bitumen, dolomite, Mn-oxides and fluorite. Three successive generations of fracture-filling calcite cements are distinguished based on their petrographical and geochemical characteristics. The oldest calcite cements (Stage 1) are moderate to dull brown cathodoluminescent, Fe-rich and exhibit intense cleavage, subgrain development and other features characteristic of tectonic deformation. Less tectonically deformed, variable luminescent Fe-poor calcite corresponds to a paragenetically younger Stage 2 cement. First melting temperatures, Te, of two-phase aqueous inclusions in Stages 1 and 2 calcites are often around 2208C, suggesting that precipitation of the cements occurred from H2O–NaCl fluids. The melting temperature, Tm, has values between 0 and 25.88C, corresponding to a low salinity between 0 and 8.9 eq. wt% NaCl. Homogenization temperatures, Th, from calcite cements are interpreted to indicate precipitation at about 708C or less. No distinction could be made between the calcite of Stages 1 and 2 based on their fluid inclusion characteristics. In some Stage 2 cements, inclusions of highly saline (up to 23 eq. wt% NaCl) brines appear to coexist with low-salinity inclusions. The low salinity fluid possibly contains Na-, K-, Mg- and Ca-chlorides. The high salinity fluid has a H2O–NaCl–CaCl2 composition. Blue-to-yellow-green fluorescing hydrocarbon inclusions composed of medium to higher API gravity oils are also identified in some Stages 1 and 2 calcite cements. Stage 1 and 2 calcites have d 18O values between 213.2‰ and 27.2‰ PDB. The lower range of the calculated d 18O values of the ambient fluids (23.5‰ to 1 2.7‰ SMOW) indicate precipitation of these cements from deeply circulating meteoric waters. The presence of petroleum hydrocarbon inclusions in some samples is interpreted to reflect partial mixing with deeper basinal fluids. The paragenetically youngest Stage 3 calcite cement has only been encountered in a fewveins.These calcites are characterised by an intensely zoned luminescence pattern, with bright yellow and non-luminescent zones. Inclusions of Mn-oxides and siliceous sinters are commonly associated with Stage 3 calcite, which is interpreted to have precipitated from shallower meteoric waters. Regional structural analysis revealed that the calcite veins of the Barrandian basin belong to a large-scale system of north–south-trending lineaments that run through the territory of the Czech Republic. The veins probably reflect episodes of fluid migration that occurred along these lineaments during late stages of the Variscan orogeny

Remote Sensing and GIS-Based Analysis of Cave Development in the Suoimuoi Catchment (Son La - NW Vietnam), 2002, Hung, L. Q. , Dinh, N. Q. , Batelaan, O. , Tam, V. T. , Lagrou, D.
Integration of remotely sensed imagery with ground surveys is a promising method in cave development studies. In this research a methodology was set up in which a variety of remote sensing and GIS techniques support cave analysis in the tropical karst area of the Suoimuoi catchment, NW Vietnam. In order to extract the maximum information from different remotely sensed data, the hue invariant IHS transformation was applied to integrate Landsat multispectral channels with the high resolution Landsat 7 ETM panchromatic channel. The resulting fused image was used, after enhancement, to visually and digitally extract lineaments. Aerial photos evaluated the extracted lineaments. Based on lineament density indices a fracture zone favorable for cave development is defined. The distance between caves and faults was investigated as well as the correspondence between the cave occurrence and the fracture zone.

Karst Springs of Alashtar, Iran, 2003, Ahmadipour, Mohamad Reza

Alashtar area is situated in the western part of Iran. The Jurassic Cretaceous dolomitic limestone covers most of the area. There are 5 karstic springs named as Amir, Chenare, Zaz, Honam and Papi. All the springs except the Papi emerge from the Jurassic-Cretaceous limestone.The Papi Spring discharges at the contact of the Jurassic-Cretaceous and the Marly limestone of Eocene age. The springs show variation of discharge during the different periods. Faults and the lineaments are the main avenues for the emergence of the springs. The springs are responsible for the rivers in the plain. The fractures are classified as thrust and normal faults. The faults are mostly formed at the junction of the surrounding carbonate rocks which give a graben structure to the plain. The springs have an important role in recharging the plain. It is due to the fractures and the springs that the plain aquifer has a high potential of water. The discharge of some of the wells is more than 60 l/s.The discharge of the springs varies considerably during the year. Out of these, the Amir , Chenare and Honam springs are considered as permanent springs. The annual discharge of the springs is 111 MCM. The hydrochemical analyses of the springs show that all of them are of carbonate type.

Intrinsic vulnerability assessment of the south-eastern Murge (Apulia, southern Italy), 2004, Marsico A. , Giuliano G. , Pennetta L. , Vurro M. ,
Maps of areas with different vulnerability degrees are an integral part of environmental protection and management policies. It is difficult to assess the intrinsic vulnerability of karst areas since the stage and type of karst structure development and its related underground discharge behaviour are not easy to determine. Therefore, some improvements, which take into account dolines, eaves and superficial lineament arrangement, have been integrated into the SIN-TACS R5 method and applied to a karst area of the southeastern Murge (Apulia, southern Italy). The proposed approach integrates the SINTACS model giving more weight to morphological and structural data; in particular the following parameters have been modified: depth to groundwater, effective infiltration action, unsaturated zone attenuation capacity and soil/overburden attenuation capacity. Effective hydro-geological and impacting situations are also arranged using superficial lineaments and karst density. In order to verify the reliability of the modified procedure, a comparison is made with the original SINTACS R5 index evaluated in the same area. The results of both SINTACS index maps are compared with karst and structural features identified in the area and with groundwater nitrate concentrations recorded in wells. The best fitting SINTACS map is then overlaid by the layout of potential pollution centres providing a complete map of the pollution risk in the area

Landform differentiation within Gunungkidul Kegel Karst, 2004, Eko Haryono And Mick Day

The Gunung Kidul karst is the western part (65%) of the larger Gunung Sewu (Thousand Hills) karst area, which is generally considered a type example of cone- or kegelkarst (Lehmann, 1936). This classification is an over-simplification, however, in that the karst landscape within the Gunung Sewu is considerably differentiated in terms of landform morphology and genesis. In the Gunung Kidul, this differentiation is evident from aerial photographs, which provide basic information about landform patterns, including lineament information. These observations were confirmed by field investigation, which incorporated landform measurement and acquisition of lithological information. These detailed studies distinguish three Gunung Kidul karst subtypes: labyrinth-cone, polygonal, and residual cone karst. The labyrinth-cone subtype occurs in the central Gunung Kidul karst where hard, thick limestones have undergone intensive deformation. Polygonal karst has developed in the western perimeter on hard but thinner limestone beds. The residual cone subtype occurs in the weaker and more porous limestones (wackestones or chalks), despite considerable bed thickness.
