N2 - New data on the petrology and geochemistry of lithologies from the mafic-ultramafic massifs of Oortsog, Dulaan, Mankhan and Yamat (Khangay upland of the Central Asian Orogenic Belt, CAOB) are presented. The petrological characteristic of the massifs, together with their inherent positive anomalies of Cs, Sr and negative anomalies of Ta, Nb, indicates that magmatism stemmed from two different mantle source regions - a mantle plume interacting with the lithospheric mantle portions of a subduction zone. The received characteristics are comparable with the data of massifs of East Kazakhstan and Western Baikal described earlier. The aim of study is identification of typomorphic features of these massifs to understand the type of mantle magmatism and geodynamic environment of region.
