Change of phlogopite composition during weathering of carbonatites and phenomenon of sorption of rare-earth elements by vermiculite
Authors:
Abstract
In the southwestern exocontact part of the Kovdorsky massif of ultrabasic, alkaline rocks and carbonatites (Kola Peninsula) there is a deposit of adatite-francolite ores, the bodies of which lie on weathered early calcite carbonatites with apatite, magnetite, sulfides and phlogopite ...
