HYDROGEOLOGICKÉ ZHODNOCENÍ CIĘŻKOWICKÉHO PÍSKOVCE NA LISTU 25-234 Horní Bečva

Roč.14,(2007)

Abstrakt

The occurrence of Ciężkow sandstone layer on map sheet 25-234 Horní Bečva is limited to narrow NW-SE zone between Vigantice and Horní Bečva. Among rocks of Flysch Belt of Western Carpathians Ciężkow sandstone has anomalous features – is very cleanly selected and silicious (80 % of quartz). Paleogene rocks and sediments (particularly their matrix) are usually calciferous. Lithological composition of Ciężkow sandstone makes specific conditions in groundwater circle and has an influent to ground water chemical composition: ground water has low mineralization and pH. Also the rock environment has similar conditions like crystalline rock environment. On surface has evolved peat bogs and specific vegetation – phytocenoses typical for acid soils without nutrients.
