Resumo
The article presents the results of a study of mineral assemblages in effusive rocks (meimechite and foidites) of the terrigenous-volcanogenic stratum of the Kontozero volcano-plutonic complex. The earliest rock, meimechite, was crystallized in the temperature range 1505—1595 °C and consist of the diopside + magnetite + phlogopite matrix with olivine (Fo84—92) phenocrysts; accessory minerals are ulvöspinel, chromite, titanite, ilmenite, and calcite. The meimechite formation led to a significant decrease in the MgO concentration and an increase in SiO2 and CaO contents and Fe2O3/FeO ratio in the magmatic melt, which determined the nature of the mineral assemblages in foidites. Thеsе rocks followed meimechite and formed at temperatures of 1325—1330 °C. In foidites, diopside crystallized in the form of phenocrysts, and previously formed olivine reacted with the melt to form symplectite intergrowths of diopside and magnetite. An increase in SiO2 and CaO contents as well as Fe2O3/FeO ratio in the sequence meimechite → foidites led to a change in the assemblage of titanium-bearing minerals. In foidites, the diversity of such minerals increases; they form zonal segregations in which, from core to rim, minerals replace each other in the following sequence: magnetite → perovskite → titanite → andradite (shorlomite).
