Mineralogy, <i>in situ</i> trace element geochemistry, and C–O isotopic composition of contaminated allanite-bearing Khaderpet carbonatite: insights regarding magmatic and supergene processes.
The Khaderpet carbonatite (1558 N, 7733 E) occur as a small plug-like intrusion (45 m x 60 m) within altered ultramafic volcaniclastic breccia of unknown parentage.Both the carbonatite and its host rock contain crustal xenoliths of granite and quartz monzonite.Although the absence of primary silicate and oxide phases obscures its direct genetic link with the host rocks, the carbonatite preserves clear evidence of magmatic crystallization subsequently overprinted by hydrothermal alteration, crustal assimilation, and supergene
