Kimberlite locations.
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.

Taking into account Clifford’s rule, the first and foremost exploration guideline for diamond exploration is the existence of a sufficiently thick lithosphere that expected to have a low surface heat flow. The Curie depth is closely related to the surface heat-flow conditions and lithosphere thickness.Kimberlite locations from publication MRD126 noted above and an addition of the Lake Ellen Kimberlite in Michigan.

Gahcho Kué is Canada's sixth diamond mine. It is located about 170 miles northeast of Yellowknife, Northwest Territories. It is a joint venture between Mountain Province Diamonds and De Beers Canada. Production began in 2016, and they propose to mine three kimberlite pipes beneath Kennady Lake.Research on the kimberlites is part of a larger Survey study of the geology of the Manhattan quadrangle, a roughly 7,200-square-mile area in north-central Kansas. That study involves mapping the area’s bedrock geology, analyzing the deep subsurface, and looking at geologic hazards such as landslides. Generalized diagram of a kimberlite pipe.

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.

The observed average distance between kimberlite clusters and the high-velocity gradient zones (HVGZ) is indicated by the red line.Aug 4, 2011 · 1980 close-up image of the razor-sharp kimberlite/granite contact in the Schaffer Kimberlite complex. Kimberlite “blue ground” (left) intruded into sheared Sherman Granite (right). The first diamond discovery in the Wyoming Diamond Province came from the Schaffer 3 kimberlite in 1975.
kimberlite: [noun] an agglomerate biotite-peridotite that occurs in pipes especially in southern Africa and that often contains diamonds.
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.
