- A type of rock (produced by volcanic activity) that can contain diamonds.
- An uneven grained, ultramafic, intrusive rock in which the visible minerals may include olivine, phlogopite, pyrope garnet, picroilmenite and chrome-diopside cemented by a groundmass, which may include serpentine, calcite and chromate. ...
- Is an magmatic rock that occurs in ancient volcanic pipes. The rock is most famous as host of diamonds, although not all Kimberlites contain diamonds. Diamondiferous imberlite occurs on ancient, Precambrean terranes, like the Baltic Shield and in Yakutia.
- A porphyritic alkalic peridotite containing abundant phenocrysts of olivine and phlogopite in a fine grained groundmass of calcite and second generation olivine and phlogopite and with accessory ilmenite, serpentine, chlorite, magnetite and perovskite. The most common host rock of diamonds.
- Intrusive igneous rock, porphyritic texture, mica peridotite, w/ most abundant mineral olivine. Contains diamonds. Often forms pipes.
