Malomurunskii is elliptical in shape narrowing towards the northeast. The complex was formed as a result of several major magmatic phases: (1) extrusion of alkaline trachytes and leucite phonolites, (2) emergence of a lopolith-like, stratified intrusion which is cut by feldspathoidal and alkaline syenite pegmatites, (3) formation of necks and extrusion of alkaline basaltoids and trachytes and (4) emplacement of concentric and radial dykes of pseudoleucite syenite porphyry (tinguaite porphyries), alkaline lamprophyres and aplitic syenites. In different parts of the complex numerous relicts of fenitized country rocks are found. The Malomurunskii lopolith consists of rocks which form
