The carbonate rocks are formed from calcium and magnesium minerals: calcite, dolomite, aragonite and magnesite, and include the two major groups: “ Sedimentary karstic rocks can be generally classified into the two major groups: Glossary for these and many other terms used in karstology is available HERE (maintained by Alexander Klimchouk et al.)īy Zoran Stevanović (Karst Aquifers – Characterization and Engineering, Springer, 2015, p. Among them are karrens or lapies, dolines or sinkholes, uvalas, poljes, blind and hanging valleys, sinking streams, caverns (Figure 3), ponors or swallow holes (Figure 4), potholes, caves (Figure 5). The list of karst features resulted from dissolution and erosional karstification processes is long and includes variety of micro and macro surficial and underground objects. This assumption can lead to serious errors in groundwater management and environmental impact assessment, because groundwater circulation can develop even though surface karst is not apparent.” Rock structure and lithology are also important: dense, massive, pure and coarsely fractured rocks develop the best karst…Experience shows that many hydrogeologists mistakenly assume that if karst landforms are absent or not obvious on the surface, then the groundwater system will not be karstic.
Considerable rock solubility alone is insufficient to produce karst. Such areas are characterized by sinking streams, caves, enclosed depressions, fluted rock outcrops, and large springs. “ We may define karst as comprising terrain with distinctive hydrology and landforms that arise from a combination of high rock solubility and well developed secondary (fracture) porosity. It is a Germanized word for “carso” (in Italian) and “kras” in (Slovene) all the three words are derived from the Indo-European word “kar” or “karra”, which means rock…Some common words from the Slavic languages of the Karst region have become international scientific terms describing karst features, mainly thanks to the Serbian geomorphologist Jovan Cvijić who was the first to defend a doctoral thesis and publish a scientific monograph exclusively devoted to karst (Cvijić, 1893).” (Figures 1,2)īy Derek Ford & Paul Williams (Karst Hydrogeology and Geomorphology, Wiley, 2007, p. “ Karst is a scientific term named after the geographic district between Slovenia and Trieste, Italy, which has a very distinct landscape.
