Циркониевая минерализация в аповулканитовых метасоматитах Ловозерского щелочного массива

The article discusses the formation of zirconium mineralization during fenitization of volcanic rocks of basic composition. The formation of own zirconium phases is associated with the addition of zirconium with alkaline melt-solutions, and the composition of these phases is due to the wave-like change in alkali concentration. Zircon crystallizes first, then, with maximum alkalinity, parakeldyshite and eudialyte. Baddeleyte is formed by changing parakeldyshite.
