简介:这份报纸为对地震导致的流动变化应答、敏感的二个地热的春天组调查了水的化学。地震监视为他们的在有在Xinyi城市Xijiang温泉和Fengshun县Shihu温泉的保存得很好的自然流动系统的居住区域被赞成。温泉在南部的瓷器广东省在温度和流动率是典型的。物理、化学的条件在内心深处在热来源是经由地观察和数字实验质问到地址的地震,液体流动,反应溶质运输和热转移,而是遗体上的重要限制。在这份报纸,我们在流动率,温度,或水的化学上做了每日、年度的观察。我们为水来源,为K长石和钠长石稳定性的平衡阶段图,和Na-K-Mg作为tracers采用了锶同位素为热水库温度的图。在Xijiang温泉的丰富的亚硫酸盐内容被讨论。我们的主要发现是深差错弹簧被低减小氧化潜力描绘在在200-附近,150mV和相对大的日报流动变化。结果关于地震监视和预言和地热的水库在地地点上提供科学背景特征。
简介:CO2富有的冷弹簧在Wudalianchi发生在活跃火山附近(),东北中国。弹簧富于CO2,与HCO3吗?作为占优势的阴离子并且提高了全部的溶解固体(TDS)的内容(>1000mg/L),Fe2+(>20mg/L),Sr(>1mg/L),并且溶解Si(>20mg/L)。弹簧的逃离并且溶解的气体的作文是类似的。在在Wudalianchi的矿泉的逃离的气体和溶解气体的13C价值变化从?8.77到?4.53并且?8.24到?5.26当18O价值变化从时?10.68到?7.65并且?10.30到?8.84,分别地在弹簧显示逃离的气体和溶解气体的CO2的一样的上面的披风起源。碳和氧同位素分别和water-CO2交换在地下水流动的过程是弱的。4He内容超过5000
