                        Raman Spectroscopy of Rocks Sections

On the following pages,  I have used the Raman microscope to study the mineralogy of rock sections.

  The red arrows in pictures indicate the position of the laser spot for each spectrum. The objectives used for pictures is 2X or 4X. For Raman spectra recording, the objective is always 50X NA=0.85. The size of the spot is 2 to 5 depending on the laser used.

 

Talc Chloritoid Garnet Schist

A small part of the thin section of this rock is reproduced on the left side; the complete thin section can be seen HERE.
