摘要：

The spinel peridotite inclusions in Sardinian basalts (M.A. 76/2650) are upper-mantle residues affected by metasomatism which led to an enrichment particularly of U and light REE. This metasomatism occurred before the recrystallization which produced the primary mineral assemblage of the inclusions. The compositional variations are taken to imply that the xenoliths are residual after at least two melting events. -R.A.H.
