Click Here For Best Selection Of High Quality Polarizing Microscope

The identification of opaque minerals is sometimes done by shining a light on top of the surface of the sample. The opaque minerals can be identified by observing the color of the reflected light through the polarizing microscope. However, this method is not encouraged because it has been found that it has some drawbacks. This is because some small grains maybe overlooked and the color that is reflected may be perceived incorrectly. Another thing is that, the possible intergrowth between minerals may not be recognized. In identifying opaque minerals, appropriate techniques should be implemented like X-ray for example. This is to justly identify the opaque mineral. It is also important to note that there are some cases where the color of the reflected light of opaque minerals maybe different from the color through the reflected light of petrographic polarizing microscope.
