摘要

在贝加尔湖裂谷系中部完整的地震地球动力学周期框架下，利用Kultuk多晶体台站2012-2022年的一系列水文地球化学数据，追踪了亲热元素Na、Li和Na/Li比值的变化与234U/238U活度比和234U活度的变化，反映了循环地下水微裂缝的开闭。从温度和地壳伸展压缩的角度考虑库拉图克地下水库的同震化学水地球动力学。

Coseismic chemical hydrogeodynamics of the Kultuk groundwater reservoir: indicator roles of the Na/Li, 234U/238U, and 234U

Within the framework of the complete seismogeodynamic cycle of the central part of the Baikal Rift System, in the series of hydrogeochemical data obtained in 2012–2022 at stations of the Kultuk polygon, variations of the thermophilic elements Na and Li and Na/Li ratios are traced in connection with changes in the 234U/238U activity ratios and 234U activity, reflecting the opening and closing of microcracks for circulating groundwaters. Coseismic chemical hydrogeodynamics of the Kultuk groundwater reservoir is considered in terms of temperature and extension–compression of the crust.
