ПЕРШИЙ ОПИС НЕМЕТАМОРФІЗОВАНИХ ВУЛКАНІТІВ НА ЛЕОНО-ЛІБЕРІЙСЬКОМУ ЩИТІ (КОТ-Д’ІВУАР)

Little known ones of volcanogenic formations described on Precambrian cratons. These rocks is the result of tectono-magmatic activation during the formation of rift structures in Central and Eastern Africa, which are also associated with kimberlite magmatism origin occurrences, seen in the states of Sub-Saharan Africa. First established volcanites is represented in lavas (rope, wrinkle, spinifex-structural and homogeneous massive lavas), pyroclastic (lapiliaceous and tuff-breccia) and mixed lava-pyroclastic facies, as well as own subvolcanic comagmata (porphyry dolerites and gabro-dolerites).
