Na prvn\u00ed pohled m\u016f\u017ee kimberlit p\u016fsobit jako pom\u011brn\u011b nen\u00e1padn\u00e1 tmav\u00e1 hornina.

Pr\u00e1v\u011b kimberlit je toti\u017e klasickou horninou spojenou s v\u00fdskytem diamant\u016f. Monastery Mine je zn\u00e1m\u00e1 jako kimberlitov\u00e1 intruze a diamantov\u00e9 lo\u017eisko, kde byl diamant skute\u010dn\u011b t\u011b\u017een.<\/p>\n
Kimberlit vznik\u00e1 z velmi hlubok\u00fdch \u010d\u00e1st\u00ed Zem\u011b a na povrch se dost\u00e1v\u00e1 prost\u0159ednictv\u00edm mimo\u0159\u00e1dn\u011b rychl\u00fdch sope\u010dn\u00fdch proces\u016f.

Kimberlit lze v ur\u010dit\u00e9m smyslu pova\u017eovat za geologick\u00fd v\u00fdtah z hlubiny Zem\u011b. Do horniny mohou b\u00fdt zachyceny tzv. xenolity \u2013 \u00falomky hornin, kter\u00e9 byly kimberlitov\u00fdm magmatem vytr\u017eeny z okoln\u00edho pl\u00e1\u0161t\u011b a dopraveny na povrch. Spolu s nimi se mohou objevit tak\u00e9 velk\u00e9 krystaly neboli megakrysty r\u016fzn\u00fdch miner\u00e1l\u016f.<\/p>\n
