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
