WebJul 28, 2000 · Kimberlites and related types of eruption are composed of a mélange of magma and rock fragments (xenoliths), broken and mixed by turbulent magmatic emplacement. The xenoliths interact with the magma, but many survive intact, thus providing clues of their original lower crustal or mantle chemistry and mineralogy. WebMantle xenoliths provide snapshots of the lithospheric mantle beneath particular regions at the time of their eruption and hence are crucial direct evidence of the nature of the mantle beneath regions where no samples have been exposed by tectonic activity.
