Kimberlite rock with diamond.
Kimberlite is found in only a small portion of Riley and Marshall counties near Tuttle Creek Lake. Lamproite, the other igneous rock in Kansas, is found in a small area along the Woodson and Wilson county line. Although diamonds occur with both kimberlite and lamproite in other parts of the world, none have been found in Kansas.
The case for a primitive kimberlite source is bolstered by the evidence that this source is deep. For the other rock types, a near-primitive isotopic composition might be explained by the presence ...kimberlite pipe model’ is a composite mode. l (Kjarsgaard, 2003; Gurney et al. 2005), as illustrated in Figure 5. The volcanic. edifice at Kasama, Mali, is 4 m high; in the Hawthorne (1975 ...Jun 19, 2021 · This type of lamproite is also diamond-bearing, though somewhat less common than breccia tuff. A third type, magmatic lamproite, filled pools of lava within the crater during later eruptions. Today it looks similar to breccia tuff but is much harder, with a rounded shape. Magmatic lamproite is not believed to contain diamonds. Kimberlites and orangeites (previously named Group-II kimberlites) are small-volume igneous rocks occurring in diatremes, sills and dykes. They are the main hosts for diamonds and are of ...

The rock kimberlite was named after Kimberley, South Africa, where it was first recognized. Kimberley diamonds were originally found in weathered kimberlite, which was colored yellow by limonite, and was therefore called yellow ground. Deeper workings produced less altered rock, serpentinized kimberlite, which miners call blue ground. Formation Kimberlite, commonly known as blue ground, is a dark-colored, massive, often altered, and brecciated (fragmented) intrusive igneous rock containing diamonds in its rock matrix. The texture is porphyritic, with massive, frequently spherical crystals (phenocrysts) surrounded by a fine-grained matrix (groundmass).

Instead of kimberlite, the host rock is lamproite. Lamproites with diamonds that are not economically viable are also found in the United States, India, and Australia. In addition, diamonds in the Wawa belt of the Superior province in Canada and microdiamonds in the island arc of Japan are found in a type of rock called lamprophyre. In contrast, kimberlite formation is thought to involve exceedingly low degrees of mantle rock melting, often less than 1%. So, another mechanism is needed.
