Abstract

Abstract

On the basis of monitoring data on geochemistry of the spring water, drip water and pool water in the Furong Cave from Mar. 2006 to Feb. 2009 and the local instrumental data, it is concluded that the concentration of Sr2+, Ca2+, Mg2+ and their ratio depending not only on the variations in precipitation and temperature but also on the overlying rock and soil. The average Ca2+ concentration in No.6 spring water out of the cave is 45.81 mg/L, but the average Ca2+ concentration in No.1 and No.3 drip water in the cave is 64.59 mg/L, but the average Ca2+ concentration in No.2 and No.4 pool water drops to 24.74 mg/L (fall by about 61.7%) leading by precipitation of Ca2+. The variations in Mg2+ and Sr2+ concentrations in the spring water, drip water and pool water are of no difference with that of the Ca2+. In each water, the Cl- concentration ranges little, averaging 1.72 ? 0.2 mg/L. The interaction time between the karst water and the bedrocks, and the prophase deposition during the transference of karst water, have important impact on the contents of each kind of element and ion. The variations of Mg/Ca and Sr/Ca, controlled by the prophase deposition in dry season and the corrosion of rocks in rainy season as well as the dilution of rainwater, could responding to extreme, drought or flood, climate events.
