Properties of individual members of this group are very similar to calcite.CarboniferouskarbonA period in paleozoic (285-350 million of years ago), in which great amount of coal was formed.cavejeskyneNaturally formed underground chamber.caving sedimentsnezpevnene nesoudrzne sedimentySedimentary rocks without cohesion.cementpojivoThe solid material that precipitates in the pore space of sediments, binding the grains together into a hard rock.cementationzpevnovaniThe process of chemical precipitation of material in the spaces between sediment grains, binding the grains together into a hard rock.CenozoickenozoikumGeological period from Tertiary (65 million of years ago) to present.cirquekarA steep-sided, amphitheater-like hollow carved into a mountain at the head of a glacial valley.clastic sedimentary rocksklasticke sedimentarni horninyA sedimentary rocks composed of fragments of preexisting rocks, formed by weathering, transportation and deposition.clastic texturesklasticke strukturyAn arrangement of rock fragments of different size of particles. This term can be used only for sedimentary rocks.clayjilSediment composed of particles with diameter less than 0,002 mm.clay mineralsjilove mineralyA hydrous-aluminium silicates that occurs as a platy grains of microscopic size with a sheet silicate structure (e.g. kaolinite, montmorillonite, illite, glauconite).clay shalejilova bridlicePelitic sedimentary rock, mostly laminated.claystonejilovecPartly lithificated pelitic sediment.cleavagestepnostThe ability of a mineral to break along preferred planes. It relates to inner structure of a mineral.cleveage planestepna plochaPlane along which mineral with cleavage breaks.cliffutesSteep, high rock on marine coast, which arose by water erosion.coaluhliA sedimentary rock formed by the consolidation of plant material. It is rich in carbon, usually black, and burns readily.coarse-grained rockhrube zrnita horninaRock in which most of the grains are from 3 to 10 mm in size.cobblevalounA sediment particle with a diameter of 64 to 256 mm.coefficient of flatnesskoeficient plochostiRatio between the longest and the shortest axis of rock fragment.columnar shapesloupcovity tvar1. Shape formed by jointing of some volcanic rocks - parallel, usually vertical columns, mostly six-sided. 2. Habitus of some minerals.compact structurekompaktni texturaType of structure of rocks, where there are no pores in a rock.compactionkompakceA loss in overall volume and pore space of a rock as a particles are packed closer together by the weight of overlying material.concordantkonkordantniParallel to layering or earlier developed planar structures.cone of depressiondepresni kuzelA depression of the water table formed around a well when water is pumped out; it is shaped like an inverted cone.confined aquifernapjata zvodenAn aquifer completely filled with pressurized water and separated from the land surface by a relatively impermeable confining bed, such as shale.confining pressurevsesmerny tlakPressure applied equally on all surfaces of a body; also called geostatic or lithostatic pressure.conglomerateslepenecA coarse-grained sedimentary rock (grains coarser than 2 mm) formed by the cementation of rounded gravel.conchoidal fracturelasturnaty lomType of fracture similar to conch surface.contact metamorphismkontaktni metamorfozaMetamorphism under conditions in which high temperature is the dominant factor.contact schistkontaktni bridliceMetamorphic rock formed usually on a contact between magma and sedimentary pelitic rock.contact-metamorphic rockskontaktne metamorfovane horninyMetamorphic rocks formed as a result of contact between magma and some rock. This type of metamorphism is
