I and M Morrison IM grain counts [#2]



I and M Morrison IM grain counts; the 0.25-0.5 mm fraction is picked for indicator minerals Cr-pyrope, eclogitic garnet, chrome dopside, Mg-ilmenite, chromite and olivine.

General Methodology:

I and M Morrison indicator mineral counts. Till samples are picked for 5 major indicator minerals (Cr-pyrope, eclogitic garnet, chrome diopside, Mg-ilmenite, chromite and olivine). Grains are examined for their color, morphology and presence of adhering kimberlite material under stereoscopic and petrographic microscopes. The 0.25-0.5 mm fraction is counted.
