Petrographic Investigations

Petrographic studies include: cutting of hand samples and drill core, polishing the cut rock for an image in the report, transmitted and reflected light images of key textures, microprobe investigations with mineral chemical analyses, backscatter electron images of key textures, and a final report detailing the findings in the sections with a geological interpretation. RGC is equipped with a trinocular polarizing petrographic microscope capable of both transmitted and reflected light optics ideal for study of silicates, oxides, and sulphides. The trinocular head is equipped with a digital camera for taking images of key textures.

Final report can include: mineral identification and modal %, mineral chemistries and rock classification, mineral textures (silicates, oxides and sulphides), colour photomicrographs, high speed backscatter images, mineral chemical graphs and petrographic interpretations.
