Most kimberlite rocks contain large proportions of ellipsoidal-shaped xenocrystic olivine grains that are de- rived mainly from disaggregation of peridotite.Kimberlite pipes. In kimberlite pipes, the eruption ejects a column of overlying material directly over the magma column, and does not form a large above-ground elevation as typical volcanoes do; instead, a low ring of ejecta known as a tuff ring forms around a bowl-shaped depression over the subterranean column of magma. Over time, the tuff ... Jan 4, 2023 · Kimberlite is an igneous rock and is considered a rare variant of peridotite. As a rock, rather than a single mineral, the chemical makeup of kimberlite varies.

Kimberlite is the name given to a silica-poor and magnesium-rich extrusive igneous rock (e.g., a volcanic rock) that contains major amounts of olivine, often serpentinized. It is a highly variable mixture of melt, minerals crystallizing from the melt, and foreign crystals and rock pieces.Kimberlite rocks and deposits are the eruption products of volatile-rich, silica-poor ultrabasic magmas that originate as small-degree mantle melts at depths in excess of 200 km. Many kimberlites are emplaced as subsurface cylindrical-to-conical pipes and associated sills and dykes. Surficial volcanic deposits of kimberlite are rare.Hypabyssal kimberlites are subvolcanic intrusive rocks crystallised from mantle-derived magmas poor in SiO2 and rich in CO2 and H2O.
