Based on chemical analysis of rocks from the Pudozhgorsky differentiated intrusive quartz dolerite sheet and two intersections differing in the degree of differentiation, the petrochemical characteristics and the composition of differentiates and the total weighted average composition of the intrusive sheet were calculated. All of the rock varieties are tholeiite-series moderate and high-K types. The initial melt, supplied to the hypabyssal chamber, is consistent with the subalkaline series. The crystallization of endocontacts and subore horizons caused by liquid immiscibility gave rise to a titanomagnetite ore horizon with the mineral paragenesis ТМТ + AVG (Wo38 En 39.8 Fs 22.2) + Pl_44-67an.
