Sövite

Jacupiranga carbonatites (sövites), intruding the clinopyroxenite body, show variable textural and mineralogical features. They are coarse- to medium-grained (grain size between 0.3 and 7 mm) and sometime banded. The main mineral assemblage of Jacupiranga carbonatites include calcite, dolomite, apatite (5 to 35%) and magnetite; olivine, phlogopite, ilmenite, pyrochlore are accessory phases. Apatite is the most important accessory phase and make Jacupiranga one of the most significant Brazilian carbonatite-hosted phosphate ores.
