In this study characteristics of drilled wells and artesian waters taken from them that occured in the formations of Quaternary, Miocene, Cretaceous, Jurassic, Triassic and Carboniferous period of the Extra Carpathian part of Małopolska province, was presented. The study area includes the central and northern part of Małopolska province, where such a morphological and tectonic units like Oświęcim and Sandomierz Valleys (the Carpathian Depression), Miechów (Nida) Trough, Śląsko-Krakowska Upland (Monocline) and Górnośląska Upland (Depression) were located. The artesian waters of study area taken from 116 drilled wells with depth from about 14,5 (Quaternary) to 1923,5 m (Miocene) and unitary yield from 0,001(Jurassic) to 375,0 (Triassic) m3·h-1·m-1 were characterised by artesian pressure from 2,0 up to 702,1 m H2O and useful pressure from 0,1 up to 18,5 m H2O. The unitary yield of Quaternary wells varied from 0,54 to 7,06 m3·h-1·m-1, Miocene wells 0.01–10.38 m3·h-1·m-1, Creatceous 0.03–52.94 m3·h-1·m-1, Jurassic 0.001-14.8 m3·h-1·m-1, Triassic 9.35-375.0 m3·h-1·m-1 and Carboniferous 2.99 m3·h-1·m-1. The highest unitary yield was detected in Triassic and the lowest in Quaternary formation. The artesian pressure ranged from 10.0 to 50.0 m H2O and useful pressure 1.0–5.0 m H2O characterised majority of wells in the study area, respectively 43 (36.8% of all) ...
In this study characteristics of drilled wells and artesian waters taken from them that occured in the formations of Quaternary period, Miocene period, paleoStefan Satora 168 gene, Oligocene, Cretaceous, Jurassic, Triassic and Carboniferous period of Małopolska province, was presented. The artesian waters taken from 116 drilled wells with depth from about 14,5 (Quaternary) to 5261,0 m (Oligocene) and unitary capacity from 0,001(Jurassic) to 375,0 (Triassic) m3·h-1·m-1 were characterised by artesian pressure from 2,0 up to 3021,0 m H2O and useful pressure from 0,1 up to 245,0 m H2O. The highest artesian and useful pressures were found in wells taken from clastic, flysh Oligocene layers of Interior Carpathian, and the lowest – in wells the was recharged by sandy-gravel of formation Quaternary. The highest amount of artesian wells on the studied area, 69 of artesian wells that constituted about 42,6% of all, is recharged by carbonate measures of Mesozoic era. ...
