The mineralogy of individual kimberlites may be ...Kimberlite, Carbonatite and Lamproite Carbonatite: a carbonate rock of apparent magmatic origin, generally associated with kimberlite and alkline rocks. They have been variously explained as derived from magmatic melt, solid flow, hydrothermal solution, and gaseous transfer. A carbonatite may be calcitic (sovite) or dolomitic (rauhaugite).Kimberlite is the source rock of more than 90% of the world's diamonds, and the geometry of a volcanic kimberlite pipe is a critical factor in defining a diamond resource. The geometry of a volcanic pipe is a consequence of the mechanical processes that occurred during its formation. Current models for kimberliteKimberlite 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 Glass - Business Information.

Diamonds in unweathered kimberlite, termed blue ground, must be extracted by crushing the rock and separating the diamonds.Kimberlite is the name given to a silica-poor and magnesium-rich extrusive igneous rock (e.g., a volcanic rock) that contains major amounts of olivine, often serpentinized. It is a highly variable mixture of melt, minerals crystallizing from the melt, and foreign crystals and rock pieces.Kimberlite is a type of igneous rock. It forms from the cooling of magma like other igneous rocks, but is unique because it forms over 100 miles (150 kilometers) beneath the Earth’s surface and, in a matter of hours, travels to the top. It is also unique because it is one of two types of rock, along with lamproite, in which diamonds are found.

Kimberlite eruption, small but powerful volcanic eruption caused by the rapid ascent of kimberlites—a type of intrusive igneous rock originating in the asthenosphere—through the lithosphere and onto the surface of the Earth. Kimberlites are thought to rise through a series of fissures in the rock.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.”Kimberlite is a relatively rare type of lava. It comes from depths as great as 300 to 350 kilometers.

It has a porphyritic texture, with large, often rounded crystals (phenocrysts) surrounded by a fine-grained matrix (groundmass).Abstract. 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. Theoretical models and empirical evidence suggest ascent along narrow (∼1 m) dykes at speeds in the range > 4 to 20 m/s. With typical dyke breadths of 1 to 10 km, magma supply ...

A rationalisation of kimberlite terminol Kimberlites are blue volcanic rocks which tend to be diamondiferous. The word kimberlite is derived from the name of the South African city “Kimberley” which developed near the country’s first significant diamond deposit.
