Propelled by a formidable volatile load, kimberlite melts transit hundreds of kilometers of mantle and crust, perhaps in just a few days, to form unique ballistic deposits at Earth’s surface. Kimberlites accumulate and transport ripped-up bits from throughout most, if not ... 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.

Kimberlite is a volcanic rock that occurs in diatremes, or narrow volcanic “pipes”. It may also occur in vertically oriented narrow sheets, or dikes. Once a kimberlite is found there is no guarantee that ... The lower part of the kimberlite pipe model is derived from the Kimberley area of South Africa, where about 1400 - 1600 m of erosion was interpreted to have occurred (Dawson, 1971; Hawthorne, 1975 ...

The kimberlite magmaclasts identified in B3 pipe (Fig. 5) are interpreted as been melt-segregations formed in this hypabyssal intrusion and their presence indicates a certain degree of modification of this magma (Scott Smith et al., 2013; Webb and Hetman, 2017), probably due to different phases of kimberlite emplacement that may be related …The passage suggests that the presence of G10 garnet in a kimberlite pipe indicates that A the pipe in which the garnet is found has a 90% chance of containing diamonds; B the levels of calcium and chrome in the pipe are conducive to diamond formation; C the pipe passed through a diamond-stability field and thus may contain diamonds; D any diamonds the …As diamond incidence is not distributed 3-021 - 100 kg 47 evenly in a kimberlite pipe, a thorough detailed diamond content (Dibbasanipalli)§ analysis using core from large diameter drilling (LDD) is very much Panna* - - - 10 cpht necessary so as to define the magnitude of diamond content of the WKF Not only just diamonds, kimberlites are ...…
