Unlike most of the surface rocks in Kansas, which are sedimentary in origin, kimberlite is an igneous rock, formed from the cooling of molten magma. Igneous rocks are extremely rare in Kansas. Kimberlite is composed of at least 35% olivine, together with other minerals such as mica, serpentine, and calcite (Jackson, 1997).1. Kimberlite Rocks. The rocks are a type of igneous rock that forms when magma flows out of deep earth fractures.

kimberlite, also called blue ground, a dark-coloured, heavy, often altered and brecciated (fragmented), intrusive igneous rock that contains diamonds in its rock matrix. It has a porphyritic texture, with large, often rounded crystals (phenocrysts) surrounded by a fine-grained matrix (groundmass).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. Below is an illustration from the Argyle Diamond kimberlite pipe model’ is a composite mode. l (Kjarsgaard, 2003; Gurney et al. 2005), as illustrated in Figure 5.
