The mentioned calciometasomatical production formed from magnesioskarns consists of harkerite, monticellite, salite-augite, grossular, gehlenite, vesuvianite and so on. It was sediment at favourable section of the various rocks of the magnesioskarns by the certain law. Formation of these mineral derived from series of mutual reaction between the skarns minerals and the components of thermal solution, and it was at the expense of special paragenesis of original minerals. The six minerals are associated each other by certain paragenesis, and its interrelation may be expressing by the triangular chemography in the ternary system Al2O,-SiO2-CaO. They make up a multisystem of six phases in the ternary system and have singular determinated topological type. The me- ntioned mineral assemblages are relate to geochemical behaviour of the iron and magnesium in the thermal solution. The chemical potential of the two components is determinate regularity of replacement of the mineral assembia- ges.
