Abstract

An increasing amount of factual data testifies to the significant role of postmagmatic phenomena in the formation of alkaline rocks. It is becoming clear that the wide variations in the structure and even composition of rocks, which are so characteristic of alkaline massifs, are to a large extent associated with postmagmatic processes. The formation of ore and rare-metal minerals in alkaline massifs is also associated with these processes. However, the question of the source of postmagmatic solutions has not yet been resolved. Most researchers consider the source of these solutions to be alkaline magma rich in volatile components, which fills the corresponding cavity, i.e., the postmagmatic phenomena described in alkaline massifs belong to the phenomena of autometamorphism (autopneumatolysis, autometasomatism). The processes of fenitization of the rocks hosting the massifs are attributed to the metasomatic processes of the magmatic stage.
