Hydrochemical fluxes and bedrock chemistry in three contrasting catchments underlain by felsic, mafic and ultramafic rocks

Popis výsledku v původním jazyce

Bedrock chemistry from three drill cores and fluxes of precipitation, throughfall and runoff from the 2015 water year were examined in three forested catchments in the Slavkov Forest, western Czech Republic. The coefficient of alkalinity of rocks at the granitic (felsic) Lysina catchment fall in the low chemical reactivity category. Rocks from the amphibolitic (mafic) Na Zeleném catchment have high reactivity and rocks from the serpentinitic (mostly ultramafic) Pluhův Bor catchment have high or even very high reactivity. Streamwater fluxes reflected the composition of the underlying bedrock lithologies, especially for magnesium, nickel and chromium at Pluhův Bor, and for calcium, arsenic and sulfur at Na Zeleném. Streamwater at Lysina reflected incomplete neutralization of acidic deposition in the catchment and had mostly negative alkalinity and correspondingly very high fluxes of potentially toxic inorganic monomeric aluminum. Internal cycling of magnesium and calcium in spruce canopy throughfall was influenced by substrate chemistry at Pluhův Bor and Na Zeleném. About half of streamwater nitrogen left the catchments in the organic form.
