Paper Abstract

Laser-excited Raman microprobe (LRM) spectroscopy has been used for the identification and non-destructive analysis of individual solid phases in mineral-hosted fluid inclusions from Brazilian alkaline rocks. Fluid inclusions from the Pocos de Caldas Massif in Brazil contain remarkable multisolid-bearing fluid inclusions. The size range of the inclusions encountered during microscope examination is between 13 and 70 μm while the solid phases are normally about 10 μm. The LRM revealed the presence of a sodium rich, carbonate-bearing mineral assemblage including the very rare strontium-cerium carbonate Burbankite, usually found in carbonatite or associated rocks.
