| The magmatic evolution is dominated by low-pressure crystal fractionation of olivine, Cr-spinel, plagioclase and clinopyroxene. |
| The fractionation, separation of active components and clarification of their mechanism of action are currently under investigation. |
| This separation creates significant fractionation during the redistribution of the chemical elements between the two liquids. |
| Suitable corrections for mass fractionation and other minor effects have been made. |
| Minimal fractionation accompanies the precipitation of pyrite from dissolved sulphide. |
| What is emerging in the place of the old multilateral approach, it appears, is a multiple fractionation of the global trading system. |
