GERAS1MOVSKY THE PEGMATITES OF THE LOVOZERO ALKALINE MASSIVE Summary The Lovozero alkaline massive (tlie Kola peninsula) is composed mainly of luyavrite and its varieties (see map, Fig. 1). Under the term of pegmatite the author moms an association of minerals formed as a result of cooling of a residual melt of nephelino-syenite magma at the period of time from the epimagmatic geophase and till' the ending in segregations of hydrothermal geophases, in cavietes or prototestonic fractures formed in the rocks of the massive due to the cooling of the latter. The shape of the pegma­ tite segregations: veins (up to 200 m, up to 1—2 m thick) an l bodies in shape resembling irregular schlieren(up to 1 m, rarely more in diameter; see Fig. 2). The pegmatites in the majority of cases occur among the rocks from which they have boon derived. Tlie geological age of the pegmatites is different and is determined by the age of the enclosing rocks. The bulk of the pegmatites was formed in the epimagmatic stage (see Fig. 3). The mineralogical compo­ sition of the pegmatites and the mineral associations observed in them are determined by the general cheaiistry of the Lovozero massive. Characteristic for it is an excess of alkalies over alumina and an enrichment in Zr, Ti and Nb. The rocks in the main have a high agpaitic coefficient up to 1.40. In some cases it is as low as 0.92. In the pegmatites 48 minerals have been found (see Table IX) . In mine­ ralogical composition the pegmatites are subdivided into 8 types (see Table IV). Each type of pegmatite formations (with the exception of the albite and zeolite ones) is observed to be confined to definite rocks composing the mas­
