CHE SIGNIFICA XENOLITH IN INGLESE
Xenolith
Un xenolito è un frammento di roccia che viene avvolto in una roccia più grande durante lo sviluppo e l'indurimento di quest'ultimo. Nella geologia, il termine xenolito viene utilizzato quasi esclusivamente per descrivere le inclusioni in roccia ignea durante il posizionamento e l'eruzione del magma. I xenoliti possono essere inghiottiti lungo i margini di una camera magma, strappata dalle pareti di un condotto lavico eruttivo o esplosivo diatreme o raccolto lungo la base di una lava fluente sulla superficie terrestre. Un xenocryst è un singolo cristallo straniero incluso all'interno di un corpo igneo. Esempi di xenocristi sono cristalli di quarzo in una lava e diamanti con deficit di silice all'interno diatremes kimberlite. Anche se il termine xenolito è più comunemente associato a inclusioni ignee, una definizione ampia potrebbe includere frammenti di roccia che sono stati racchiusi in roccia sedimentaria. A volte i xenoliti si trovano in meteoriti recuperati. Per essere considerato un vero xenolito, la roccia inclusa deve essere identicamente diversa dalla roccia in cui è avvolta; Una roccia inclusa di tipo simile è chiamata un autolito o un'inclusione congiunta.
definizione di xenolith nel dizionario inglese
La definizione di xenolite nel dizionario è un frammento di roccia che differisce per origine, composizione, struttura, ecc. Dalla roccia ignea che lo racchiude.

High Quality Content by WIKIPEDIA articles! A xenolith (Greek: "foreign rock") is a rock fragment which becomes enveloped in a larger rock during the latter's development and hardening.
Jesse Russell, Ronald Cohn,

If one can determine the depth from which xenoliths come by therrnobarometry,
and estimate the relative abundances of various xenolith populations in the crust,
it should be possible to reconstruct a crustal cross-section (Kay and Kay, 1981).
