The Problem of Phoscorite Petrogenesis on the Example of Arbarastakh and Gornoye Ozero Massifs (Republic of Sakha, Yakutia)

The paper considers the problem of petrogenesis of phoscorites and related carbonatites using the example of the Arbarastakh and Gornoye Ozero massifs (Republic of Sakha, Russia). The petrographic and mineralogical studies showed that phoscorites can have different genesis – both magmatic and metasomatic. Different genesis results in the different distribution of minerals responsible for the ore potential of phoscorites.
