The Vuoriyarvi massif belongs to the Paleozoic intrusive complex of ultrabasic alkaline rocks and carbonatites of the Kola Peninsula and Northern Karelia. Deposits and ore deposits of various ore and non-metallic minerals are confined to such massifs. Each type of minerals belongs to certain rocks composing a complex complex: ultrabasic rocks - titanium and phlogopite-vermiculite mineralization, carbonatites - rare elements. The issues of mineralogy, petrography and genesis of Vuorijärvi massif were paid much attention by many researchers. We have made an attempt on the basis of field studies to present the structure of the massif and the history of its formation ...
