Altai collision system of Hercynides was formed in Late Paleozoic as a result of oblique collision of Siberian continent and Kazakhstan composed terrane [Vladimirov et al., 2003; 2008; Xiao et al., 2010]. At the late stages of its evolution (time interval from 310–300 to 280–270 Ma) the huge different mafic and felsic magmatism occurred at the territory (Fig. 1) [Vladimirov et al., 2008; Khromykh et al., 2011, 2013, 2014, 2016; Kotler et al., 2015; Sokolova et al., 2016]. It is evident about increased thermal gradient in lithosphere and about significant role of mantle and active manifestation of mantle-crust interactions. Some magmatic complexes may be considered as indicators of mantle-crust interaction processes.
