Abstract

This paper presents results of 2025 sampling of steam vents and thermal waters in the Nizhne-Koshelevsky and Verkhne-Koshelevsky thermal fields. We considered macrocomponent composition of water (рН, SO₄, Cl, NH₄, and H₃BO₃) and the chemical composition of gases, including hydrocarbons up to C₆. We are the first to report data on the isotope composition of water, carbon in CО₂ and CН₄, sulfur in H₂S, and dissolved sulfate. We discuss possible factors that have affected the differences in the chemical and isotope compositions of fluids in the thermal fields of the Koshelevsky volcanic massif.

俄罗斯堪察加科舍列夫斯基火山地块热液和气体的化学和同位素组成(H-O-C-S

本文介绍了在尼日涅-科舍列夫斯基和维尔赫内-科舍列夫斯基热场进行的2025年蒸汽喷口和热水取样的结果。我们考虑了水的宏观成分组成（рН， SO4, Cl， NH4和H3BO3）和气体的化学成分，包括碳氢化合物直至C6。我们是第一个报告水的同位素组成、CО2和CН4中的碳、H2S中的硫和溶解的硫酸盐的数据。本文讨论了影响科舍列夫斯基火山地块热场流体化学和同位素组成差异的可能因素。

期刊介绍： Journal of Volcanology and Seismology publishes theoretical and experimental studies, communications, and reports on volcanic, seismic, geodynamic, and magmatic processes occurring in the areas of island arcs and other active regions of the Earth. In particular, the journal looks at present-day land and submarine volcanic activity; Neogene–Quaternary volcanism; mechanisms of plutonic activity; the geochemistry of volcanic and postvolcanic processes; geothermal systems in volcanic regions; and seismological monitoring. In addition, the journal surveys earthquakes, volcanic eruptions, and techniques for predicting them.
