The article focuses on the late cretaceous age of ongonite from the Far East. Topics discussed include the age of subvolcanic analogs of Li–F granite (ongonite), evolution of leucogranite magma for progressive accumulation of fluorine and water, and ongonite being a reliable indicator of chambers of deep differentiation of the granite magmas. It also discusses the age of the formation and the place of ongonite in the evolution of rare-metal granite magmatism.
