We interpret these grains as xenocrysts from an older source terrain from which the granitic protolith of sample MS 3 may have been derived by anatectic melting. |
Again, the lack of zircon xenocrysts in this sample does not allow discrimination between these alternatives. |
The presence of anomalously large plagioclase crystals, which may be xenocrysts, is the main reason for the success of those sites while other sites are not. |
Kimberlites contain, in addition to diamond xenocrysts, fragments of lherzolites of varying composition. |
No distinction of potential xenocrysts was made. |
Xenoliths and xenocrysts provide important information about the composition of the otherwise inaccessible mantle. |
