摘要

文章介绍了 2021 年对下-沙平斯基(基佩利)二氧化碳热泉(39°C)进行水化学研究的结果。泉水在克孜门活火山附近的 Shchapinsky 地堑内排放。研究结果包括宏观和微观成分组成、源水的同位素组成、一些游离气体成分以及溶解的锶。研究利用以前公布的数据和档案数据对结果进行了讨论,考虑到了该地区的地质和结构位置、水与岩石的相互作用,并利用简单的热化学计算解释了一些二氧化碳水的化学成分中罕见但具有特征性的现象,即镁比钙占优势。研究表明,下-沙平斯基泉水是由两种成分混合形成的:更深、更受热的氯化钠水和更表层、受热较少的水,其成分为 Mg-Ca-\({text{HCO}}_{3}^{- }\) ,这是与含碳酸盐岩和火成岩源二氧化碳相互作用形成的。

Nizhne-Shсhapinsky Thermal Springs (Kamchatka) as an Example of Magnesium Carbon Dioxide Waters

Nizhne-Shсhapinsky Thermal Springs (Kamchatka) as an Example of Magnesium Carbon Dioxide Waters

The article presents the results of hydrochemical studies of the Nizhne-Shchapinsky (Kipely) carbon dioxide thermal (39°C) springs in 2021. The springs are discharged within the Shchapinsky graben near the active Kizimen volcano. The results include macro- and microcomponent composition, isotopic composition of source water, some free gas components, and dissolved strontium. The results are discussed using previously published and archive data, taking into account the geological and structural position of the area, water–rock interaction, as well as using simple thermochemical calculations in order to explain the rare, but characteristic of the chemical composition of some carbon dioxide waters, predominance of magnesium over calcium. It has been shown that the waters of the Nizhne-Shchapinsky springs are formed as a result of mixing of two components: deeper and more heated sodium chloride water and more surface, less heated water with the composition Mg–Ca–\({\text{HCO}}_{3}^{ - }\), formed due to interaction with carbonate-bearing rocks and CO2 of igneous origin.

期刊介绍: Russian Journal of Pacific Geology publishes the results of research on the Earth crust and mantle composition and provides articles on the geological structure and patterns of distribution of mineral deposits in the Pacific Ocean, marginal seas and continental margins. It discusses the topics of stratigraphy, sedimentology, magmatic activity, and seismicity. The journal deals with the problems of lithosphere plates tectonics, and offers the results of neotectonic, geomorphological, geodesic, environmental and mining studies in the Pacific region. The journal accepts theoretical, methodical and philosophical articles covering general issues of geology, geophysics, geochemistry, geoecology and mining. The journal also publishes critical notes and comments, and reviews.
