| Popis: |
A detailed study in thin section of a set of 330 fresh small xenoliths from the brown breccia within a deep level of the Udachnaya kimberlite pipe allowed us reconstruction of the mantle section from 8.0 to 1.0 GPa, which represents 6 main capturing intervals. Interaction of the protokimberlite melt with the deeper level was responsible for peridotite heating, shearing, metasomatism, and remelting of eclogites. The most compositionally and thermally diverse mantle horizon is detected from 7.0 to 5.0 GPa. The pyroxenite-rich levels are found in the lithosphere base, near 4.0 GPa and in the upper part at 30–2.0 GPa. |
