Fig. 1.6. The rock cycle. Rocks are weathered to form sediment, which is then buried. After deep burial, the rocks undergo metamorphosis or melting, or both. Later they are deformed and uplifted into mountain chains, only to be weathered again and recycled. Some injection of rock from the upper mantle is irreversible, that is, non-cyclic.

Although present in small amounts, mafic rocks (here defined as those with MgO > 4 wt % ) are particularly interesting since they represent the closest relatives of primary melts generated in the upper mantle. [Pg.4]

Hf-isotope ratios also fall close or within the field of crustal rocks (Fig. 2.4 Table 2.2). This has been interpreted as evidence that metasomatic modification of lamproitic mantle sources in Tuscany was provided by addition of crustal material (e.g. metapelites). Interestingly, the mantle-normalised incompatible element patterns of Tuscany lamproites are similar to those of gneisses and schists in almost eveiy detail. This has been interpreted as evidence for addition of bulk upper crustal material to the mantle, with little element fractionation during metasomatism and the subsequent partial melting (Peccerillo 2002). This makes the Tuscany Province a zone where the upper mantle magmas look very much like the upper crust in terms of trace element and radiogenic isotope compositions. [Pg.41]
