| 英文摘要 | We present Mg and Fe isotopic data for whole rocks and separated minerals (olivine, clinopyroxene, orthopyroxene, garnet, and phlogopite) of garnet peridotites that equilibrated at depths of 134-186 km beneath the Kaapvaal and Siberian cratons. There is no clear difference in delta(26) Mg and delta(56) Fe of garnet peridotites from these two cratons. delta(26) Mg of whole rocks varies from -0.243% to - 0.204% with an average of -0.225 +/- 0.037% (2 sigma, n = 19), and delta(56) Fe from -0.038% to 0.060% with an average of -0.003 +/- 0.068% (2 sigma, n = 19). Both values are indistinguishable from the fertile upper mantle, indicating that there is no significant Mg-Fe isotopic difference between the shallow and deep upper mantle. The garnet peridotites from ancient cratons show d 26 Mg similar to komatiites and basalts, further suggesting that there is no obvious Mg isotopic fractionation during different degrees of partial melting of deep mantle peridotites and komatiite formation. |
