摘要
为探明东滩矿区奥陶系灰岩地下水水化学特征及其成因,采用数理统计、Piper三线图、离子比例系数和饱和指数SI等方法对东滩矿区奥陶系灰岩地下水水化学特征及其成因进行分析。研究结果表明:研究区奥灰水水化学类型主要为SO_(4)-Ca·Mg和SO_(4)-Ca型;离子比例系数法表明奥灰水中离子主要来源于蒸发岩的溶解;饱和指数法表明石膏是研究区奥灰水中的反应性矿物。
In order to find out the groundwater hydrochemical characteristics and genesis of Ordovician limestone in Dongtan mining area, the hydrochemical characteristics and genesis of Ordovician limestone in Dongtan mining area were analyzed by means of mathematical statistics, Piper three-line diagram, ion proportional coefficient and saturation index SI. The results show that the hydrochemical types of Ordovician ash water in the study area are mainly SO_(4)-Ca·Mg and SO_(4)-Ca. The ion proportional coefficient method shows that the ions in Ordovician ash water mainly come from the dissolution of evaporite. The saturation index method shows that gypsum is a reactive mineral in Ordovician ash water in the study area.
