Perovskite, Alkaline rocks, Carbonatites, Eastern ParaguayAbstract
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 trachytic rocks and defines an evolutionary trend represented by an increase of Sr and LREE. The crystallization of the perovskite-group minerals resulted probably from metasomatic processes caused by fluids derived from cognate alkaline or carbonatitic sources, at relatively low temperatures (e.g. 400-700°C)Downloads
