Carbonatite-Alkaline Magma Immiscibility Conducing to Carbonatite REE Enrichment
2018Carbonatite is a particular type of magmatic rocks enriched in REE relative to the majority of igneous rocks. Among the numerous carbonatites referenced worldwide, only a few of them contain economic REE concentrations widely considered as resulting from late- to post- magmatic processes.

FENITES ASSOCIATED WITH CARBONATITES
The Canadian Mineralogist, 2008A review of occurrences of potassic and sodic fenitization around carbonatites is presented, including several new examples and oceanic ones. Taken in conjunction with the many examples quoted in the literature, conclusions are drawn that the K and Na contents of carbonatitic melts that induce fenitization are primary constituent parts of both ...

Apatite from African carbonatites
Lithos, 1973Abstract Apatite from three African carbonatites (sovites) are of the carbonate-hyoxy-fluorapatite type with a marked similarity in composition and structural formula. However, apatite from an apatite-magnetite dyke, associated with a carbonatite complex, differs in Ca, P and trace element content.

Mineralogy of carbonatite-breccia: Amba Dongar carbonatite diatreme, Gujarat, India
Carbonatite-breccia forms a major unit in the carbonatite-alkaline diatreme of the Amba Dongar carbonatite ring complex. In addition to the innermost part of the ring strucure, small and large plugs outside the ring structure are also formed in the form of discontinuous rings around the sövite.Schulzki, Jan +2 more
