Late Cenozoic volcanism at the northeastern flank of the South Khangai volcanic region (Central Mongolia): Geochronology and formation conditions

A study investigated Late Cenozoic volcanism at the northeastern flank of the South Khangai volcanic region (Central Mongolia). In general, the data suggest similarity of the Orkhon-Selenga and Khangai areas in terms of different (age, structure, and lithology) characteristics. Hence, these areas be...

Description
Summary:A study investigated Late Cenozoic volcanism at the northeastern flank of the South Khangai volcanic region (Central Mongolia). In general, the data suggest similarity of the Orkhon-Selenga and Khangai areas in terms of different (age, structure, and lithology) characteristics. Hence, these areas belong to a single region. We believe that the peculiarities of its structure and evolution are related to the South Khangai hot spot of the mantle (or mantle plume), the manifestation area of which in the lithosphere was complicated by the boundary between the microplates.
