本研究的目的是评估水的化学类型的定义，特别注意苏打卤水的特点，通过评估离子组成和pH值在大的地理尺度和广泛的盐度（TDS）范围内的欧亚内陆咸水表面沃茨，以纠正相当大的混乱苏打湖和锅的确切化学分类。pH值和八种主要离子浓度的数据已汇编到来自奥地利、中国、匈牙利、哈萨克斯坦、蒙古、俄罗斯、塞尔维亚和土耳其的数据库中。分类主要基于占总阳离子或阴离子的25当量百分比（> 25e%）以上的主导离子，还确定了主导离子的e%等级。我们确定了四种主要类型：（1）Na-HCO 3（10.0%），（2）Na-HCO 3 + CO 3（31.4%），（3）Na-Cl（45.9%）和（4）Na-SO 4（12.7%）为主的沃茨，仅考虑第一种离子的e%等级。考虑到所有主要离子的e%等级，这些主要类型可以在数据集中分为30个亚型。苏打卤水的主要类型和亚类型可分为“苏打型”和“苏打盐水型”。当Na+和HCO 3- + CO 32-占优势离子的第一位（> 25 e %）时为“苏打型”，当Na+占优势阳离子的第一位且HCO 3- + CO 32-浓度之和超过25 e %时为“苏打-盐水型”，但在优势阴离子的第一位时不是“苏打-盐水型”。从卤水饱和度指标的地球化学解释来看，碱盐型可视为介于碱盐型和咸盐型之间的一个独立的演化阶段。所获得的分布中的重叠范围表明，单独的pH测量不是对永久性碱性“苏打类型”和各种其他类型的临时碱性沃茨水进行分类的可靠指标。
The aim of this study is to evaluate the definition of water chemical type, with particular attention to soda brine characteristics by assessing ionic composition and pH values on a large geographic scale and broad salinity (TDS) range of Eurasian inland saline surface waters, in order to rectify the considerable confusion about the exact chemical classification of soda lakes and pans. Data on pH and on the concentration of eight major ions were compiled into a database drawn from Austria, China, Hungary, Kazakhstan, Mongolia, Russia, Serbia, and Turkey. The classification was primarily based on dominant ions exceeding an equivalent percentage of 25 (> 25e%) of the total cations or anions, and the e% rank of dominant ions was also identified. We identified four major types: waters dominated by (1) Na-HCO3 (10.0%), (2) Na-HCO3 + CO3 (31.4%), (3) Na-Cl (45.9%), and (4) Na-SO4 (12.7%), considering only the first ion by e% rank. These major types can be divided into 30 subtypes in the dataset, taking into account the e% rank of all dominant ions. The major and subtypes of soda brine can be divided into “Soda” and “Soda-Saline” types. “Soda type” when Na+ and HCO3– + CO32– are the first in the rank of dominant ions (> 25e%), and “Soda-Saline type” when Na+ is the first in the rank of dominant cations and the sum of HCO3– + CO32– concentration exceeds 25e%, but it is not the first in the rank of dominant anions. Soda-saline type can be considered as a separate evolutionary stage between Soda and Saline types respect to the geochemical interpretation by saturation indexes of brines. The obtained overlapping ranges in distribution demonstrate that a pH measurement alone is not a reliable indicator to classify the permanent alkaline “soda type” and various other types of temporary alkaline waters.
