It is rich in mica minerals content and often in form of crystals of phlogopite. Other containt abundant minerals are chrome-diopside, olivine, and chromium- and pyrope-rich garnet .For the upcoming expedition, the junior explorer has scheduled a four-week project that will include collecting approximately 200 bulk samples to help define kimberlite indicator mineral trains.

Kimberlites, small-volume volcanic rocks that are the source of most diamonds, offer rare insights into aspects of the composition of the Earth’s deep mantle. …compositions of kimberlites define a series of trends that appear to be derived, at least in part, from the fractionation or accumulation of olivine. The composition of the olivine that controls each trend corresponds to that of olivine of the lithospheric mantle through which the kimberlite passed on their way to the surface.
