Perovskite-group minerals of alkaline-carbonatitic rocks from the Rio Apa and Amambay regions in Eastern Paraguay are members of the perovskite-lueshite-loparite-latrappite solid-solution series. Strontian-loparite is prevailing in the fenitized trac

ABSTRACT: This paper reviews general aspects of alkaline-carbonatitic rocks of Brazilian, Paraguayan and Bolivian terrains. Although 30 such occurrences are known in literature, only the major ones have been thoroughly investigated. The carbonatites

We present a comprehensive overview of the geochemical characteristics and evolution of the carbonatites from the southern Brazilian Platform (Paraná Basin). The carbonatites from different complexes display large compositional variability in terms
