Resumo


Fluid inclusion study in opaque minerals using IR micloscopes and cameras is known since 1984. Using IR diodes and lamps coupled to petrographic microscope and Fluid Inc. heating/freezing stage, microscopy and microthermometry in sphalerite, wolframite, and hematite have been performed at the CDTN fluid inclusion laboratory. The obtained results and constraints to the used technique are presented.
