The records and implications of Mg, Sr and Ba in cave water and active speleothems in Jiguan Cave, western Henan Province

  • 摘要: 采用电感耦合等离子体质谱仪(ICP-MS)和电感耦合等离子体光谱仪(ICP-OES)对2009年12月-2013年8月采自河南省栾川县鸡冠洞洞穴水(滴水、池水及地下河水)和现代碳酸盐沉积物的Ca、Mg、Sr和Ba微量元素地球化学指标进行了分析。结果显示:(1)鸡冠洞洞穴水的Mg/Ca对地表环境的干湿条件变化响应迅速,具体表现为池水和地下河水Mg/Ca旱季高而雨季低,而Sr/Ca和Ba/Ca的变化与降水和气温的关系并不明显;(2)鸡冠洞现代沉积物的Mg/Ca变化与滴水有着良好的对应关系,但现代沉积物的Sr/Ca和Ba/Ca可能受大气粉尘活动和地表土壤的影响,变化趋势与Mg/Ca相反;(3)鸡冠洞碳酸盐岩与岩溶水间Sr/Ca和Mg/Ca的分配系数KSr值在0.02~0.18之间,KMg值在0.01~0.03之间,KMg值与洞穴温度的正相关关系不明显。
