“Roots” of magmatic systems in the large continental igneous provinces

Our study is mainly aimed at concretization of the ideas on the structure of the front parts of mantle plumes, their material, the level of penetration into the lithosphere, and the conditions of magma generation from an example of mantle xenoliths in basalt of the Quaternary Tell Danun Volcano, Harrat Ash Samah volcanic plateau adiabatic, South Syria. Xenoliths are the fragments of the upper cooled head of the mantle plume above the zone of adiabatic melting. Both materials were involved in melting. The earlier melts were alkaline FeTi basalts and basanite enriched in fluid components and often containing mantle xenoliths.
