“…Magnetite is an accessory mineral in foidolite, diopsidite, phlogopite glimmerite and dolomite carbonatite, an accessory or minor rock-forming mineral in forsteritite, apatite-forsterite phoscorite and vein calcite carbonatite and a major mineral in all other types of phoscorite and carbonatites. Its morphology, anatomy, grain size and chemical composition vary corresponding to the concentric zonation of the phoscorite-carbonatite pipe [16,40]. In addition, magnetite always contains exsolution inclusions of spinel and/or ilmenite-geikielite [40][41][42], providing a means to estimate the thermodynamic conditions of exsolution using the Fe-Al and Fe-Ti oxide geothermobarometers.…”

“…В России одним из крупных его источников является Ковдорское месторождение магнетита, апатита и бадделеита [1,2]. Основным концентратором скандия является бадделеит, который включает этот металл по схеме 2Zr4+ ↔ Sc 3+ Nb 5+ [3]. Содержание ниобия и скандия в бадделеите последовательно возраста-ет от краевой части трубки, сложенной (апатит)-форстеритовыми фоскоритами, к промежуточной зоне бескарбонатных существенно магнетитовых фоскоритов и, далее, к осевой зоне карбонатсо-держащих фоскоритов и карбонатитов (рис.…”
