What is kimberlite.

The kimberlite volcanic rocks are assigned to the sedimentary strata in which they are intercalated, e.g., Cantuar-equivalent kimberlite, when this is known. The kimberlite samples investigated in this study were collected from drillcore, excepting the Sturgeon Lake samples that are from an ice-rafted megalith “outcrop.”The surface anomalies of kimberlite, identified in this research, substantiate the importance of detected anomalies for further exploration.Diamond-laden magmas apparently rapidly rise from deep within the Earth to the planet's surface by jettisoning weight, scientists now find.

Kimberlite is a potassic to ultrapotassic magnesium oxide-rich (15-27 wt. % MgO), silica poor (20-36 wt.% SiO 2) ultramafic rock. This rare rock is rich in volatiles, incompatible elements, and rare Earth elements (REE) and has considerable magnesium, iron, and calcium oxides.The Grib kimberlite is located in the central part of the ADP within the Chernoozero kimberlite field (Fig. 1).Based on phlogopite megacryst Rb-Sr isotopic compositions, the Grib kimberlite has an age of 376 ± 3 Ma (Larionova et al., 2016).The Grib kimberlite is classified as a Fe-Ti series and moderate Ti type (1.0-2.0 wt.% TiO 2) among the ADP kimberlites (Kononova et al., 2006 ...

Kimberlite often contains fragments of upper-mantle derived ultramafic rocks, including xenocrysts such as pyrope garnet, picro-ilmenite, chromian spinel and chrome-diopside.

Kimberlite deposits are commonly highly altered, contain abundant xenoliths and xenocrysts from both mantle and crustal sources, and are likely partially or wholly degassed. 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 ...

Kimberlite formation is a complex process involving magma rising quickly through the Earth’s mantle, carrying fragments of rock and minerals from deep within. As this magma reaches the surface, it explodes, creating an impact crater known as a maar. Kimberlite formation is unique due to its explosive nature.Kimberlite Partners Profile and History .
