kimberlites but a wide range of minerals occur in related rocks. Other macrocrysts (e.g. pyrope garnet, chrome diopside) are xenocrysts derived mainly from mantle peridotite, eclogite and the megacryst suite (used here in petrogenetic sense ). For descriptive purposesBut by November 2002, a solution to certify that diamonds were conflict-free was finally in place. They called this the Kimberley Process Certification Scheme (KPCS) or Kimberley Process for short. In a nutshell, the Kimberley Process’ purpose is to prevent conflict diamonds from entering the mainstream diamond-trade market.Hypabyssal kimberlites are subvolcanic intrusive rocks crystallised from mantle-derived magmas poor in SiO2 and rich in CO2 and H2O. They are complex, hybrid rocks containing significant amounts of mantle-derived fragments, primarily olivine with rare diamonds, set in a matrix of essentially magmatic origin.Kimberlite is a crystal to help you reach your true potential. It encourages self-confidence, living in the moment, and living your truth. It helps you to complete projects or your life purpose. It promotes flexibility and the ability to see what is coming next. It is a protective stone that teaches how to let go of resistance.

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 .Kimberlite is a volcanic rock containing isolated pieces of rock or crystal that were pushed up out of the earth’s mantle by magma. Kimberlite can be identified by its fine-grain texture, its blue or yellow color, and/or the presence of diamonds and other gems in the rock.Diatreme. A diatreme, sometimes known as a maar-diatreme volcano, is a volcanic pipe associated with a gaseous explosion. When magma rises up through a crack in Earth's crust and makes contact with a shallow body of groundwater, rapid expansion of heated water vapor and volcanic gases can cause a series of explosions.

Further, their great depths of origin make it very likely that the melt composition, temperature and volatile content vary with depth due to assimilation, crystallization ...Bulk kimberlite versus mantle peridotite compositions. The average Mg/Si ratios for bulk kimberlites from 10 on- and off-craton locations in southern Africa, Canada, West Greenland, and Siberia are compared with the average Mg/Si ratios of their entrained coarse-grained, well-equilibrated peridotite xenoliths from these same localities in Fig. 1.The Mg/Si ratio was chosen because it is ...…

Upper mantle xenoliths are found in some kimberlite and provide clues to the magma's origin.Kimberlite and kimberlite-microbreccia are found in at least eight breccia-filled dikes in northern Arizona and southeastern Utah and have been described by Watson (1967) and McGetchin (1968).

Kimberlite volcanism involves the ascent of low viscosity (0.1 to 1 Pa s) and volatile-rich (CO2 and H 2O) ultrabasic magmas from depths of 150 km or greater.
