That fracture is 1. a break or secondary discontinuity in the rock mass, whether or not there has been relative movement across it. faults, thrusts, and joints are all fractures, but bedding planes, which are primary features, are not. in a more strictly hydrogeological context the term has been used to classify voids in the size range 0.1 to 10mm [9]. 2. breakage of rock strata [16]. 3. the general term for any mechanical discontinuity in the rock; it is, therefore, the collective term for joints, faults, cracks, etc. see also conduit; fissure.?

Detailed tectonic trends on the central part of the Hellenic Outer Ridge and in the Hellenic Trench System, 1982, Kenyon N. H. , Belderson R. H. , Stride A. H. ,
Extensive new sonograph coverage in the Eastern Mediterranean allows a re-assessment of the complex relief outside the Hellenic Arc. The trenches to the SE and SW of Crete are similar in their plan view appearance, each having predominantly sinuous or curved structures that are interpreted as the surface expression of major thrusts. Thrusting, possibly imbricate, is also suggested on the central, shallowest part of the Hellenic Outer Ridge where interlocking convex-outward, curved structures occur, along with other faults and folds. These are thought to relate to decollement-type displacement within or beneath evaporite sediments. The structural style deduced from the morphology is consistent with a continuing outward radial push of the Hellenic Arc to the SW, S and SE, rather than with a migration to the SW and strike-slip on the SE side of the arc as proposed by other workers

Problemas de Fugas a Traves dei Karst en la Presa de Tous (Espana) (Anlisis estructural, prevision del comportamiento y recomendeciones)., 1983, Bermejo Fernando, Pablo Cano Juan, Del Val Joaquin, Eraso Adolfo, Navarro Jos Vicente, Parra Felix, Ribelles Jesus, Saintaubin Julia, Valdes Consuelo
In the present work, the problems of leakages happened in Tous's dam (Valencia-Spain) are studied. Tous's dam is built on karstic terrains with the existence of caverns and strike-slip faults that at the same time become karstic. In this study the techniques of structural geology are applied, so, we deduct the karstic drainage directions, by using determined hypothesis of work. The confirmation of these hypotheses in the course of our fieldwork has permitted to quantify the probability of those leakages for each direction we found. This circumstance has permitted to foretell the places where it would be possible to expect leakages with the increase of the height of the dam foreseen for a second phase of building.

Karst development and the distribution of karst drainage systems in Dejiang, Guizhou Province, China, 1983, Song Linhua, Zhang Yaoguang, Fang Jinfu, Gu Zhongxong,
The nature of karstification of two contrasting areas on the north Guizhou Plateau (south China) is shown to be controlled by structure, lithology, geomorphic history and tectonics, and causes significant differences to arise in the subsurface drainage systems of the areas.The Shaqi area lies in a syncline of Permo-Triassic limestones underlain by an insoluble sandy shale which forms the local base level. Karst landforms are strongly influenced by the presence of four erosion levels corresponding to four periods of rejuvenation of the drainage systems. Drainage is concentrated along the syncline axis, and one system (Naoshuiyan) has been pirating another (Lengshuiyan) by headward retreat. Cave passages are typically phreatic.The Dejiang Town area lies in an anticline of Cambrian dolomite and Ordovician limestone. Three large subsurface drainage systems have developed along parallel faults, and have typically vadose cross-sections

The role of the subcutaneous zone in karst hydrology, 1983, Williams Paul W. ,
The subcutaneous zone is the upper weathered layer of rock beneath the soil, but above the permanently saturated (phreatic) zone. It is of particular hydrological importance in karst because of its high secondary permeability, arising from the considerable chemical solution in this zone. However, corrosional enlargement of fissures diminishes with depth; thus permeability decreases in the same direction with the result that percolation is inhibited, except down widened master joints and faults. Storage of water consequently occurs in this zone, particularly after storms. The upper surface of this suspended saturated layer in the subcutaneous zone is defined by a perched water table, which slopes towards points of rapid vertical percolation. The potential induces lateral water movement converging on the most permeable areas such as beneath dolines. Leakage from the subcutaneous store sustains slow percolation in the vadose zone. Cross-correlation of rainfall with percolation rates in caves in New Mexico, U.S.A., and New Zealand reveal response lags of 2-14 weeks with no apparent relationship to depth below the surface. Other percolation sites show no correlation with rainfall; interpreted as being a consequence of considerable friction in tight fissure networks. The recognition of storage and rapid as well as very slow percolation from the subcutaneous zone requires re-interpretation of the components of hydrographs from karst springs and of some conceptual models of karst aquifers. The importance of subcutaneous storage in sustaining baseflow discharge at some sites must be recognised, as must the contribution of subcutaneous water to flood hydrographs. Methods of estimating the volumes of subcutaneous and phreatic components of karst-spring flood hydrographs are presented. The paper concludes with a discussion of the significance of subcutaneous hydrologic processes for an understanding of karst geomorphology. The desirability of explaining karst landform evolution in terms of hydrologic processes is stressed

Hydrogologie karstique des Alpes-Maritimes, 1984, Baissas, P.
Karst hydrogeology in the Alpes-Maritimes - In the Marguareis, the systems penetrate very quickly by transverse faults, to reach the impermeable basement and then follow the dip. All the waters, even those on the French side, belong to the P basin. In the Roya arc, underflows are to be found going round the base of the Argentera-Mercantour. In the Nice arc, the karstification depends principally on tectonic factors and according to the places, the water follows either the overlaps or transverse faults. In the Grasse plateaus, the galleries follow at the outset the slopes and the dips of the synclinal hinges; the tectonic factors determine the location of the resurgences ; at depth, the karst is always phreatic, with relations between tectonic compartments during floods. In the cover of the Tanneron-Esterel basement and Barrot Dome, lithological factors determine flow.

Karsts alpins et notectonique, 1984, Julian, M.
ALPINE KARSTS AND NEOTECTONIC: A BRIEF OVERVIEW - Several problems are studied at the light of new investigations: 1) the deepening of the karstic network related to orogenic uplifts and the corresponding levels of the caves; 2) the tectonic deformations (faults) described upon some karstic surfaces or into some caves; 3) the pseudo-tectonic deformations like toppling failures and other tension-cracks parallel to the vertical cliff faces.

Un haut plateau jurassien : le plateau des Molunes (Jura), 1984, Neyroud, M.
LARGE KARSTIC DEPRESSIONS AND ANTICLINAL STRUCTURES ON A HIGH JURASSIC TABLE-LAND: THE SOUTH OF THE PAYS MOLUNOIS (JURA, FRANCE) - On a high Jurassic table-land, the Pays molunois, close to the Monts Jura (Crt de la Neige, 1717m), large karstic depressions are studied in connection with anticline structures. Along a single anticline crest, a great diversity of forms is explained by the character of strike-slip faults (direct tectonic control), the glacial heritage (regional ice-cap), the tardiglacial evolution (peat-bogs or molunes), the lithological context (minor morphology) and at last unequal anthropic action. The morphogenesis of an original type of small anticlinal valleys, the closed anticline valleys-poljes is considered dating from geomorphologic evolution of the area and particular tectonic context.

Le massif du Parmelan, Haute-Savoie, relations fractura-tion-karstification, 1985, Masson, M.
THE MASSIF OF PARMELAN, HAUTE-SAVOIE, FRANCE: RELATIONS BETWEEN FRACTURATION AND KARSTIFICATION - The massif of Parmelan (Haute-Savoie), encloses a well-karstified and highly organised perched aquifer. Its simple geological structure and easy-speleological penetration (more than 45km are known) have allowed a statistical study of the fracturation and karstification parameters at different scales. This study shows that the karst has developed on the most frequent fracturation directions (study of the cumulated lengths), whereas its directional distribution in frequency is relatively homogeneous; the most used fractures are the tension faults, linked with the folding of the massif.

Prsentation du Causse Comtal (Aveyron), 1987, Solier, P.
THE " CAUSSE COMTAL " (AVEYRON, FRANCE): GEOLOGY, HYDROGEOLOGY AND INVENTORY OF MAIN CAVES - The " Causse Comtal " (S = 265 km2) forms a sedimentary bridge between the " Causses du Quercy " in the west and the " Grands Causses " in the east. With a middle humid climate (P = 1000 mm/y, T = 9,4 C, Evap. = 450-500 mm/y), this plateau karst presents two aquifer levels in the Lower and Middle Jurassic separated by a marly layer. These formations cover a paleozoic basement (sandstone, argillite from Carboniferous and Permian, crystalline rocks). The hydrogeological basins are controlled by E-W reverse faults due to the N-S pyrenean compression. The main spring is near Salles-la-Source in the western part (average discharge: 840 l/s; flood : 10 m3/s); it drains a 50-55 km2 area. The morphological and speleological evolution is subordinated to an erosion surface from Upper Cretaceous - Tertiary. Often stopped up (blocking), the numerous fossil caves probably date from the end of Cenozoic era. The large subterranean passages (active or semi-actives galleries; ex.: Tindoul de la Vayssire) are plio-quaternary.

Le karst pliocne de la rgion de Safi (Maroc atlantique), 1987, Weisrock A. , Lunski S.
POST-PLIOCENE KARST OF SAFI AREA (ATLANTIC MOROCCO) - The karst of Safi area is developed in bioclastic calcarenites of Plio-Moghrebian upon Mesozoic limestones, marls and gypsum. Dolines, uvalas and poljes are found along faults N170-N195, N040-N070, N080-N115, which are mainly " Mesetian " and " Atlasic " tectonic directions of Atlantic Morocco. Two points are developed upon this karst genesis: 1/ the relations between post-pliocene karstic landforms and paleokarst in limestones and gypsum; 2/ the recent karstic developments occur during the periods wetter than today (310 mm/y), for example Upper Pleistocene, as it is showed by dating of charcoal in dolines filling.

Relationships between the internal and external evolution of the Monte Cucco Karst Complex. Umbria, Central Italy., 1987, Guzzetti Fausto
The relationships between the internal and external evolution of the Mt. Cucco karst complex are studied. A classic set of equations, involving the oxidation of hydrogen sulphide, originated at depth in an evaporitic formation, is used to explain the presence of massive gypsum deposits in the Mt. Cucco and the Faggeto Tondo caves. The distribution and the morphology of more than 30 caves in the system, the presence of gypsum, always located along faults, and the presence of broken stalactites and columns, suggest that the evolution of the karst system has been controlled by tectonic movements. Relationships between the development of the caves and the geomorphic evolution of the area are proposed.

Subsidence associated with the abstraction of fluids, 1988, Bell Fg,
Subsidence of the ground surface due to the withdrawal of groundwater, oil, gas or brine from sedimentary deposits has ccurred in many parts of the world. The abstraction of groundwater has been the principal cause of subsidence, primarily because more groundwater is abstracted than all the other liquids put together. Subsidences of several metres have been recorded, for example, in California due to the exploitation of oil, as well as groundwater. Such ground movements represent a notable problem in engineering geology. Generally these subsidences take place slowly but the occurrence at the surface of sinkholes as a result of water tables being lowered in limestone terrains is a rapid process. In the case of groundwater, gas or oil abstraction the reduction in pore pressure in the voids due to the decline in head leads to an increase in effective load on the sediments concerned, bringing about consolidation, which is reflected at the surface as subsidence. On the other hand when mineral deposits are worked by solution mining the rock material itself is removed which, if uncontrolled, resultsin subsidence. The removal of fluids from sediments frequently has resulted in the formation of fissures at the surface. Indeed there are cases on record where faults are alleged to have been formed. Such fissures often occur around the periphery of the subsidence trough
