What is a kimberlite
Kimberlite is an igneous rock that major source of diamonds. Kimberlite is a variety of peridotite . 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 .Those Kimberlites date to at least a billion years old. So that suggests the Hope diamond and similar diamonds found in India were brought to the surface at least a billion years ago and perhaps ...

Pipa kimberlite ini merupakan sumber berlian yang paling signifikan, namun diperkirakan hanya 1 dari setiap 200 pipa kimberlite yang mengandung berlian berkualitas permata. Nama “Kimberlite” sendiri berasal dari kota Kimberley di Afrika Selatan, tempat berlian pertama ditemukan pada jenis batu ini.Hypabyssal kimberlites are subvolcanic intrusive rocks crystallised from mantle-derived magmas poor in SiO 2 and rich in CO 2 and H 2 O. 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 magmas tend to be volatile, erupting at speeds of more than 100 feet per second (30 meters per second) and pulling diamonds from the surrounding rocks …Kimberlites. While all of the volcanism discussed so far is thought to originate from partial melting in the upper mantle or within the crust, there is a special class of volcanoes called kimberlites that have their origins much deeper in the mantle, at depths of 150 km to 450 km. During a kimberlite eruption, material from this depth may make ...
Usage. Although Kimberlite Ore is a rare resource that offers a unique crafting recipe, it is not incredibly valuable. Its primary use is the creation of Diamond. Diamonds can be created by smelting Kimberlite Ore in a single step which can be convenient early game. Because Diamonds are smeltable from Energetic Graphite there is little reason ...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.”Kimberlites are rare volcanic rocks with unusually deep origins. This Review explores the origin and evolution of kimberlite melts and their insights into mantle composition and …Kimberlites are usually carrot-shaped, as the lighter rock very close to the surface tends to give way during the eruption process, and the kimberlite explodes outward in all directions. This is why most kimberlites lend themselves well to open-pit mining, often followed by underground mining. In some cases, kimberlites can fissure at the ...
The kimberlite is high in magnesium, carbon dioxide, and water. The kimberlite is the primary source of diamond, precious gemstone, and semiprecious stones.

Kimberlite is a type of igneous rock. Olivine is the most abundant mineral found in kimberlite but other minerals that may be found in kimberlite include phlogopite, mica, diopside, and calcite. Much of the diamonds presently mined come from kimberlite ores. Kimberlite can be hard to identify, as it comes in many colors.

An unusual magmatic process is a kimberlite pipe, which is a volcanic conduit that transports ultramafic magma from depths in the mantle to the surface. Diamonds, which are formed at great temperature and depth, are transported this way to locations where they can be mined.... kimberlite. Accurate classification of magmaclasts in coherent and volcaniclastic kimberlites is fundamental for the development of valid geological models ... ku gps pipes differ from kimberlite pipes in that the magma contains boiling water and volatile compounds that corrode the overlying rock. The result is a broad cone at the earth’s surface that narrows into a pipe. Lamproite pipes are a less frequent source of diamonds than kimberlite pipes.
