DOI: 10.1016/j.jseaes.2021.104773
Abstract: Abstract Carbonatite from the Arabian-Nubian Shield of Sudan occurs as dykes in the Nuba Mountains. It is composed of calcite with some feldspars, quartz and fluorite. CaO is the major constituent in this carbonatite and… read more here.

Interaction of mantle magmas and fluids with crustal fluids at the 1894 Ma Montviel alkaline-carbonatite complex, Canada: Insights from metasomatic and hydrothermal carbonates
Sign Up to like & getrecommendations! Published in 2018 at "Lithos"
DOI: 10.1016/j.lithos.2017.11.027
Abstract: Abstract Alkaline and carbonatite rocks are relatively rare but offer the opportunity to study the contribution of fluids in the genesis of mantle and crustal rocks because they are commonly affected by metasomatism. Carbonate minerals… read more here.

DOI: 10.1016/j.oregeorev.2019.103294
Abstract: Abstract Carbonatites are abundant in the rare earth elements (REE), and they host the most important REE resources in the world. However, the mechanisms that concentrate these elements during carbonatitic magmatic processes are still poorly constrained. Here,… read more here.

DOI: 10.3390/min8060260
Abstract: The world largest phoscorite-carbonatite complexes of the Kovdor (Russia) and Palabora (South Africa) alkaline-ultrabasic massifs have comparable composition, structure and metallogenic specialization, and can be considered close relatives. Distribution of rock-forming sulfides within the Kovdor… read more here.
