Crustal melting, probably triggered by the emplacement of mafic melts, with generation of peraluminous, highly silicic magmas which were emplaced either as unmodified melts or mixed with different... 

The Tuscany Magmatic Province consists of an association of calc-alkaline to lamproitic mafic to intermediate magmas and silicic intrusive and effusive rocks. Silicic melts have been formed by crustal melting, with an important role of mixing with mantle-derived magmas. Mafic melts are of mantle origin but resemble closely some upper crustal rocks, such as metapelites, in terms of incompatible trace elements and radiogenic isotope...

Ta/La and Ti/Zr values are a feature of the parental crustal melts (Clarke, 1990). Similarly, the TTG have low Ta/La and Ti/Zr and no clear intrasuite correlations between them, although that may, in part, reflect the large-scale sampling of many studies.

In (i)-(iii), delamination would be unnecessary if primitive cumulates or residues of lower crustal melting were ultramafic, and remained present below the seismic Moho. However, the absence of pyroxenite layers —10 km in thickness in the Talkeetna and Kohistan arc sections suggests that large proportions of ultramafic, igneous rocks are not present at the base of arc crust.
