The Isotope Composition of Helium in the Late Cenozoic Southern Baikal Volcanic Area and Southern Khangai Volcanic Area
This paper deals with the isotope composition of helium (3Не/4Не = R) in the groundwater of the Southern Baikal volcanic area (SBVA) and Southern Khangai volcanic area (SKhVA) during the Late Cenozoic Period. We have found differences in the behavior and value of that parameter. It was found that the differences in the concentrations of 3Не/4Не in the SBVA and the SKhVA resulted from mantle reservoirs that have different isotope compositions of helium. This confirms that the Late Cenozoic volcanism in the SBVA and SKhVA is controlled by mantle sources related to mantle plumes of the Central Asian hot mantle field.
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.
