Un élément incompatible est un élément qui, lors d’un processus de fusion, va se concentrer principalement dans la phase liquide. Lors des phénomènes de fusion partielle du manteau qui auraient donné naissance à la croûte, les éléments incompatibles se seraient concentrés dans la phase liquide, qui en se refroidissant forme la croûte continentale, laissant un manteau résiduel appauvri. C'est ce manteau résiduel qui serait échantillonné par les basaltes des rides océaniques. 2, record 1, French, - %C3%A9l%C3%A9ment%20incompatible

We can often differentiate between these two sources (crustal and mantle) by examining variations in 34S/32S. ... Originally, all the earth's sulphur was in the mantle. Much of that transferred to the crust has undergone biogenic fractionation .... It is now held to be an oversimplification to claim that for all natural sulphur a narrow range of [delta]34S close to zero indicates a mantle source, and a wide range of [delta]34S a crustal source. 3, record 4, English, - mantle%20source
