What is kimberlite.

Kimberlite is a type of rock best known for sometimes containing diamonds. It is named after the town of Kimberley in South Africa, where the finding of a large kimberlite pipe in the 1870s spawned a diamond rush. Kimberlite has in many ways attracted more attention than its relative volume might suggest that it deserves.[1] Kimberlites, the deepest terrestrial magmas and the principal source of diamonds, must have low viscosity and high buoyancy, which govern their exceptionally fast transport from mantle depths to the surface. Appreciation of the rheological properties of kimberlite magmas relies on research into their temperatures and compositions. …Kimberlite may be the end product of reaction between granitic crustal rocks and a carbonatitic magma, and emplacement may have occurred as diatremes above parent dike systems (Dawson, 1967a). This theory assumes that a fluid mush of highly gas-charged kimberlite has been injected as dikes along deep-seated tension fractures, part of the ...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. The radiogenic isotope ratios of ...

INTRODUCTION. Kimberlite, as illustrated in Figs 1 and 2, is a rock dominated by olivine.Most kimberlites are highly altered and their primary textures are poorly preserved, but rare examples, such as the sample from the Kangamiut region of Greenland shown in Fig. 1, contain about 50% of large fresh olivine grains, which are set in a matrix of finer-grained minerals.This paper documents the application of a microdiamond-based approach to the estimation of diamond grade in the Pipe 1 kimberlite at the Koidu mine in Sierra Leone. A geological model of Pipe 1 was constructed to represent the distribution and volume of the dominant kimberlite units within the pipe. Bulk samples, along with representative …

It may be distinguished from jadeite ( q.v. ), jade's other form, by ...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. Kimberlite rocks are created inside the earth's crust in the form of perpendicular structures called kimberlite pipes.

The Sloan kimberlite in Colorado was mined on a trial basis in 1994, and some 9,034 diamonds weighing a total of 342 carats were recovered from 3,300 tons of rock excavated from a 614-ft adit.

Some magma composi-tions found in the Navajo Volcanic Field rocks are similar to kimberlites, but noKimberlites are often closely associated, both in time and space, with a wide variety of alkaline ultramafic rock types, yet the question of a genetic relationship between these rock types remains uncertain. One locality where these relationships can be studied within the same cluster is the Karelian craton in Finland.

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 purposes
