[Un des] facteurs [...] [pouvant] expliquer la plupart des grandes variations dans la composition des roches ignées [est la] «Différenciation par débit gazeux» : à mesure que la cristallisation se produit dans un magma, les gaz dissous deviennent de plus en plus concentrés, puisque les cristaux qui se forment ne contiennent pas de composés volatils. Cette concentration provoque une augmentation de la pression de vapeur dans la poche magmatique. Dans certains cas, les gaz peuvent exercer une pression supérieure à la résistance de la poche; ils s'échappent alors vers le haut. Des bulles montent à travers le magma. On pense que ces gaz peuvent entraîner une partie du liquide résiduel hors de la phase cristalline pendant les dernières étapes de la cristallisation. 2, record 1, French, - transfert%20des%20substances%20volatiles
