CONTENT OF RUBIDIUM IN BERYLS FROM PEGMATITE VEINS IN THE KOLA PENINSULA (O Sodezhani ubiiya V Berilakh Pegmatitovykh zhil Kol' Skogo Poluotrov) by T. F. orovik-Romanova and A. F. Sosedko.

Rb was found in all Kola Peninsula beryls investigated. The Rb content has a definite relationship to the paragenetic associations of minerals surrounding it. For the North Kola pegmatite belt the beryls are characterized by very low concentation of Rb less than 0.0033%; in beryls from the contact zone (0.018%) to the center (up to 0.110%). The Rb content runs in the same direction in other minerals. In the microcline boundary zone of the pegmatite vein the Rb content was 0.3%, whereas in microcline from the central part of the same vein it reached 1.20%. Potassium was constantly present in the Rb containing beryls. Both these elements, evidently, are substituting Cs. (Author)
