Kimberlite, and rocks with kimberlitic affinities, have a relatively wide distribution throughout the United States. They occur in the western margin of the Appalachians from New York to Tennessee; in the central region of the U.S. including Kentucky, southern Illinois, Missouri, Kansas and Arkansas, and in the Western States of Montana, Colorado, Wyoming and the Colorado Plateau.

In this study, we assess the diamond exploration potential of the northern East European Platform based on aeromagnetic survey results and the morphologic and geochemical analysis of 1513 grains of kimberlite indicator minerals (KIMs), such as purple pyrope garnet, olivine, and Cr-diopside. These minerals were recovered from samples collected from modern river and stream sediments in four ...

Oct 16, 2015 · Kimberlite is an ultramafic rock derived from the mantle. Diamonds crystallize in the mantle well below the crust but they are carried up into the crust by the rising kimberlitic magma. Only 1% of kimberlite is economic and these are almost always found in or above Archean cratons. Sub-Sahara in Africa and Russia together produce 80% of the ...

For example, as pressure drops during ascent, the kimberlite magma is not able to dissolve as much carbon dioxide, and a fluid rich in carbon dioxide and water exsolves from the magma. (figure 1; Brey and Ryabchikov, 1994). This fluid, which often dissolves diamond, normally starts to exsolve at around 3–4 GPa (a giga­pascal is a unit …
