ODM KIM count (inc low-Cr diopside)

Kimberlite indicator mineral grain counts.  The grains identified are peridotitic garnet (GP), eclogitic garnet (GO), chrome diopside (DC), Mg-ilmenite (IM), chromite (CR), forsteritic olivine (FO) and low-Cr diopside (LCD).

General Methodology:

Overburden Drilling Management kimberlite indicator mineral (KIM) counts.  Minerals are preconcentrated from bulk samples with respect to density and magnetism, then picked for grains indicating kimberlites.  Chrome diopsides (distinctly emerald green) and low-Cr diopsides (paler emerald green) are distinguished.
