Abstract
Laser-excited Raman microprobe (LRM) spectroscopy has been used for the identification and nondestructive 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 mu m while the solid phases are normally about 10 mu m. 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.
