Kimberlite locations.

The material referred to as kimberlite, also called blue ground, is a dark-colored, often fragmented, intrusive rock that may contain diamonds in its rock matrix. It is named after the town of Kimberley, South Africa, where in 1869 the discovery of an 83 carat diamond inside kimberlite rock spawned the world’s largest diamond rush.

Diamonds form isometric crystals, have ...In places there is a 1 to 1.3 m marginal zone within the pipe where the kimberlite is sheared, with mud seams and calcite veins. The Letšeng kimberlites belong to the group 1 class of kimberlites, the generally non-micaceous type. Their texture is volcaniclastic.

Two locations in the United States have been worked as commercial diamond mines. The first was a mine near Murfreesboro, Arkansas. It was worked as a commercial diamond mine by a succession of operators in the early 1900s but closed because the deposit was subeconomic. Today it is known as the "Crater of Diamonds" and is operated by the State ...

Kimberlite magma can rise toward the surface at speeds estimated at up to 400 meters (1,200 feet) per second, ripping up more and more pieces from the surrounding rock, which gives the kimberlite its characteristic texture (fig. 3). Figure 2--Generalized diagram of a kimberlite pipe. Figure 3--Polished kimberlite core sample. Kimberlite, and rocks with kimberlitic affinities, have a relatively wide distribution throughout the United States.

The peridotite "family" contains a number of different intrusive igneous rocks. These include lherzolite, harzburgite, dunite, wehrlite, and kimberlite (see photos).

Jul 17, 2023 · Kimberlite chemical composition. 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. Schematic diagram of a kimberlite pipe. An unusual magmatic process is a kimberlite pipe, which is a volcanic conduit that transports ultramafic magma from within the mantle to the surface. Diamonds, which are formed at great temperatures and pressures of depth, are transported by a Kimberlite pipe to locations where they can be mined.This enabled them to generate a map of the likely location of kimberlites across the Earth’s surface. Treasures beneath Africa The resulting map (above) shows that 80% of kimberlite locations (black dots on the map) should lie within or alongside the African continent in a relatively narrow ring.Instead, locations farthest from the cratonic edge appear to preserve the deepest lithospheric roots in Alberta. 5.3 Relationship with spatial distribution of diamondiferous kimberlites.
