【摘要】 2002年9月采集了莱州湾沿岸地下卤水样品。分析结果表明,这些卤水来源于海水,但两者间已有了一定的差别。在卤水形成及以后的变化过程中,水-围岩间发生了明显的物质交换作用,其中对K+的影响最大,进而推出海水与粘土的交换是K+从海洋输出的重要形式。更多还原

【Abstract】 The chemical composition of underground brine samples in the coast area of Laizhou Bay was analyzed.The results suggest that the underground brines in this area originated from seawater.However,some differences were found among them.There were obvious water-rock interactions between underground brines and surrounding rock after the formation of brines.K+ is the most affected ion by water-rock interaction.Therefore,the exchange of K+ between seawater and clay is the important transport form of K+ from the seawater.更多还原
