Kimberlite Pipes Map. Lithoquest Discovers Two New Kimberlites on the North Kimberley Diamond Project Mining Stock The mantle is nearly 100 miles below the Earth's surface, and gems that come from the mantle are brought to the surface by kimberlite pipes, which are formed by deep-source volcanic eruptions. [ 25 ] The discovery of diamond-rich kimberlite pipes in northern Canada during the early 1990s serves as a prime example of how challenging these deposits can be to locate, as their surface features are often subtle.

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 A number of other regions that have seen much less exploration, such as the Birch Mountains, Mountain Lake, Caribou Mountains, Chinchaga River, Peace River to Spirit River, Kakwa-Wapiti River, Edmonton and south-central foothills areas, and much of central to southern Alberta across the Prairies, require further exploration to identify the potential for kimberlite pipes and to determine the.

It is a highly variable mixture of melt, minerals crystallizing from the melt, and foreign crystals and rock pieces Kimberlite volcanism involves the emplacement of olivine-rich volcaniclastic deposits into volcanic vents or pipes
Kimberlites Earth’s Diamond Delivery System Gems & Gemology. As of 2014 about 6,400 kimberlite pipes are known on Earth including about 900 that have been found to contain diamonds, with mining of diamonds occurring at about 30 pipes The eastern (leading) edge of Farallon slab in central North America at 100 and 90 Ma (at 403 km depth) are shown as thick and thin black-dashed line, respectively [after Spasojevic et al ., 2009 ].
