Breakthrough in Research and Dating of Latest Volcanism in the Baikal Rift System and its Significance for Understanding Latest Geodynamics of Asia
The history of studying and dating the latest volcanism of the Baikal Rift System (BRS) is conventionally divided into stages: 1) until the 1950s (discovery of young volcanoes), 2) 1950–1960s (primary determination of the age of the Cenozoic volcanogenic-sedimentary sequences using paleontological data), 3) 1970–1980s (determination of sequence of volcanic strata in the development of relief and pioneering radioisotope dating of volcanic rocks), 4) 1980–2005 (growth of geochronological and geochemical data on volcanic areas of Asia), and 5) 2005–2023 (synthesis of geochronological and geochemical data). The breakthrough in studying and dating of latest volcanism in the BRS resulted in substantiation of the development of mantle melting anomalies in the Japan–Baikal Geodynamic Corridor (JBGC) and its overlap by the Indo-Asian Convergence Region. A breakthrough in studying and dating of volcanic rocks that occurred by 2012 was basically confirmed by mass 39Ar/40Ar dating of 2018 in Central Mongolia.
期刊介绍：
Italian Journal of Engineering Geology and Environment (IJEGE), published by Sapienza Università Editrice university press, is the open access Journal of the Research Center CERI on "Prediction, Prevention ad Control of Geological Risks" of Sapienza University of Rome. The Journal publishes original papers concerning the numerous topics of environmental risks such as seismic risk, landslide risk, hydraulic and flood risk, groundwater resource management, soil and groundwater contamination, reclamation of contaminated land, applied geophysics, economic geology, land use, soil and rock characterization. IJEGE is the Journal of the Italian Association of Engineering Geology and Environment (AIGA). The Journal is published under the auspices of the International Association for Engineering Geology and the Environment (IAEG) - Italian Group.
