That fault is 1. a fracture in the earth's crust, across which relative rock movement has taken place, or continues to take place. fault planes commonly guide vertical or sub-vertical shafts in caves, as well as guiding sub-horizontal or oblique passages within the confines of the fault plane [9]. 2. a fracture or fracture zone along which there has been displacement of the two sides relative to one another parallel to the fracture [6]. this displacement may be of a few centimeters or many kilometers. see also joint fault set; joint fault system.?

Bullita cave system, Judbarra / Gregory Karst, tropical Australia, 2016, Grimes K. G. , Martini J. E. J.

In the monsoon tropics of northern Australia, Bullita Cave is the largest (123 km) of a group of extensive, horizontal, joint-controlled, dense network maze caves which are epikarst systems lying at shallow depth beneath a well-developed karrenfield. The Judbarra / Gregory Karst and its caves are restricted to the outcrop belt of the thin, sub-horizontal, Proterozoic Supplejack Dolostone. Karst is further restricted to those parts of the Supplejack that have escaped a secondary dolomitisation event. The karrenfield and underlying cave system are intimately related and have developed in step as the Supplejack surface was exposed by slope retreat. Both show a lateral zonation of development grading from youth to old age. Small cave passages originate under the recently exposed surface, and the older passages at the trailing edge become unroofed or destroyed as the, by then deeply-incised, karrenfield breaks up into isolated ruiniform blocks and pinnacles. Vertical development of the cave has been generally restricted to the epikarst zone by a 3m bed of impermeable and incompetent shale beneath the Supplejack which first perched the water-table, forming incipient phreatic passages above it, and later was eroded by vadose flow to form an extensive horizontal system of passages 10-20m below the karren surface. Some lower cave levels in underlying dolostone occur adjacent to recently incised surface gorges. Speleogenesis is also influenced by the rapid, diffuse, vertical inflow of storm water through the karrenfield, and by ponding of the still-aggressive water within the cave during the wet season – dammed up by “levees” of sediment that accumulate beneath the degraded trailing edge of the karrenfield. The soil, and much biological activity, is not at the bare karren surface, but down on the cave floors, which aids epikarstic solution at depth rather than on the surface.


A Three-dimensional Statistical Model of Karst Flow Conduits, 2016, Boudinet, P

It already exists several three-dimensional models dealing with groundwater circulation in karst systems. However, few of them are able either to give a large scale prediction of the repartition of the flow conduits or to make a comparison with real field data. Therefore, our objective is to develop a three-dimensional model about the early formation of karst flow conduits and to compare it with actual field data. This geometric and statistical model is based on percolation and random walks. It is computational and can be run on a personal computer. We examine the influence of fissures (joints and bedding planes) of variable permeability and orientations on the development or early flow conduits. The results presented here correspond to computations up to 2015. Because of long runtimes, we focused on some particular stereotypical situations, corresponding to some particular values of the parameters. Regarding the conduit patterns, the opening and directions of fissures have the same qualitative influence in the model than in actual systems. Two other predictions in good accordance with real karst are that flow conduits can either develop close to the water table or deeper, depending on the distribution of permeable fissures; and that, when viewed in the horizontal plane, conduits don't always develop close to the straight line between inlet and outlet. From a quantitative point of view, in the case of weak dips, our model predicts a realistic relationship between the stratal dip, the length of the system and the averaged depth of the conduits. Eventually, we show that the repartition of conduits depends not only on obvious geometrical parameters such as directions and sizes, but also also on other quantities difficult to measure such as the probability of finding open fissures. The lack of such data doesn't enable, at the present time, a whole comparison between model and reality.


State of the art of karst vulnerability assessment: overview, evaluation and outlook, 2017,

The study gives an overview of the evolution of the concepts and approaches to karst groundwater vulnerability, its connections to previous vulnerability evaluations and of the steps proposed for the assessment. The majority of the methods are based on prerequisites derived from the basic processes of shallow karst systems in the form of transferred parameters. A systematic survey of existing methods and their applications highlights the significance of scale, parameters, its intrinsic or specific and source or resource nature. Revealing the relationships between methods helps to understand their innovations, advantages, disadvantages and the data need. Based on the literature study, the critical examination of the physical reliability of the resulting vulnerability maps and the necessity of their validation is also highlighted. The paper considers the possible and desirable directions for further research, including the development of process-based methods and involvement of an understanding of the flow and transport processes of karstified carbonates. However, the various aspects of water management are not discussed in the present study.
