PHOSPHATE-FLUORIDE-CARBONATE MINERALIZATION IN LAMPROITE ROCKS OF THE RYABINOVY PLUTON (CENTRAL ALDAN): MINERALOGICAL AND GEOCHEMICAL FEATURES AND ORIGIN [PDF]
Минералогия, 2017 Carbonate and apatite-fluorite mineral assemblages are studied in lamproite rocks from high-K Ryabinovy intrusive (Central Aldan, Russia). It is concluded that these assemblages are genetically related and belong to the same apatite-fluorite-carbonate ...

Journal of Metamorphic Geology, Volume 44, Issue 6, Page 440-469, July 2026.ABSTRACT Understanding the pressure of emplacement of granitic intrusions is crucial to understanding the exhumation history of plutons and constraining the tectonic setting of magma emplacement. However, P–T and geochronological constraints from exhumed plutons are often characterized by large uncertainties, especially in shallow crustal settings with

IOP Conference Series: Earth and Environmental Science, 2008 Lamproites are mantle-derived ultrapotassic volcanic rocks, derived from phlogopite-bearing harzburgitic source. The origin of the metasomatism which enriched their mantle source is either an old event with a metasomatic component derived from the convecting mantle, or is a more recent introduction of an already aged metasomatic component.
