title: [Seasonal Variations and Controlling Factors of the Element Contents in Drip Waters Collected from the Baojinggong Cave in Guangdong Province].
abstract: Geochemical dynamics of cave water were monitored to unveil its seasonal variation and controlling factors from December 2011 to May 2013 in Baojinggong cave, north of Guangdong Province. Concentrations of elements such as Ba, Sr, Ca and Mg of three drips in the cave were analyzed. The results showed that: (1) All these elements of three drips displayed significant seasonal variations, but the trends of seasonal variation of different elements or different drips were not the same, which reflected that each element in different drips might be controlled by different effects; (2) The low element contents of Drip1 and Drip2 during the heavy rainfall month showed that heavy rainfall could dilute the concentrations of elements; (3) Mg/Ca had a positive relationship with Sr/Ca ratio in three drips, and was higher in dry season and lower in rainy season. It implied that the two proxies might be mainly controlled by precipitation, karst water source, leaching effect and prior calcite precipitation (PCP), and reflected the climate change.
