白水台钙华区水化学特征及泉华沉积过程研究

Sedimentary Process and Water Chemistry Property of Contemporaneity Sinter in Baishuitai

对白水台冷泉型淡水碳酸盐现代泉华沉积过程的野外观察和对泉水流动与泉华沉淀过程中各部位所取水样的现场和室内水化学分析所获得的数据,揭示出泉华沉积过程分为放气和沉淀两个阶段.这两个阶段在水体外貌与泉华堆积地貌上均有明显的表现.研究表明,压力减小、水温升高、水层变薄、藻类与细菌繁殖以及强水动力等条件在泉华沉积过程中起着十分重要的作用.

This paper is based on the field survey of sedimentary process of carbonate in cold spring freshwater of contemporaneity sinter in Baishuitai and the data obtained from the analysis on the chemistry of the water locale and indoor. The water sample was gained from spring flowage and sinter sedimentary process. It opens out the process of sinter sedimentation contain of two phases： deflation and sedimentation. These two phases perform absolutely in water exterior and sinter sedimentary physiognomy. By studying, the decrease of press are, the hoist of water temperature, the attenuation of water layer, the propagation of alga and bacteria and etc play an important part in the sinter sedimentary process.
