Mineral compositions and Sr-Nd isotope compositions of the Kovdor ultramafic alkaline carbonatitic complex
Abstract:
Ultramafic alkaline–carbonatite complexes (UACCs) display exceptional lithological and mineralogical diversity, yet the processes generating this complexity remain debated. We investigate the Kovdor massif (Kola Alkaline Carbonatitic Province, Russia) as a case study to evaluate the role of replacive magmatic processes in UACC evolution. New field observations, petrography, mineral chemistry, trace-element data, and Sr–Nd isotopic analyses reveal that much of Kovdor’s lithological diversity formed through pervasive melt–rock reactions between earlier cumulates and later carbonate-rich and melilitolitic melts.
