确定了氮温泉中 δD 和 δ18O 值与溶解硅浓度之间的负相关性，这证明了在水-岩系统相互作用过程中，其氢同位素组成向贫化重同位素的方向发生了直接变化。对于气象成因温泉的同位素组成相对于当地大气降水的同位素组成较轻的情况，可以考虑这一事实。温泉同位素组成点相对于全球大气水位线的变化可能是由氧或氢组成的变化引起的。
The negative correlation between values δD and δ18O and concentrations of dissolved silicon in nitrogen hot springs is ascertained, which attests to the directed alteration of their hydroisotopic composition towards being depleted in heavy isotopes during interaction in the water-rock system. This fact can be allowed for the cases of the lighter isotopic composition of the hot springs of meteogenic origin relative to that of local atmospheric precipitation. The shifts in points of isotopic composition of hot springs from the global meteoric water line can be caused by alterations in either oxygen or hydrogen composition.
