Evidence for the multi-stage petrogenetic history of the oka carbonatite complex (québec, canada) as recorded by perovskite and apatite...(e.g., ijolite, alnöite), and their relative emplacement history is uncertain....
A novel hybrid carbonatite formed by assimilation of ijolite... A microxenolith of ijolite exhibits similar reaction phenomena....
Nepheline sövites as parental magmas in carbonatite complexes: evidence from... Rock types range from early nepheline sövites through sövite and hypothesis being that ijolite–carbonatite pairs represent conjugate liquids, derived by immiscible separation fromdolomite alvikite to late-stage ferroan carbonatites....
The geology of the southern part of homa mountain carbonatitic complex, western kenya, with particular reference to the petrology of the alkaline silicate, metasomatic and melilite bearing suites.... The earlier events included intrusion of a body of ijolite, as a series of discontinuous bodies probably connected at depth....
