This magmatism was largely the result of anatexis forming migmatites and large plutons.
2.
At shallow depth, magma generation is dominated by anatexis of the slab.
3.
Incapillo magmas probably formed as adakitic high-pressure mafic magmas derived from the crust, either directly by anatexis or indirectly by dragged-down crustal fragments.
4.
The change in plate movements and increased melt generation caused an overturn and anatexis of the melt generating zone, forming a density barrier for mafic melts which subsequently ponded below the melt generating zone.
5.
However, it is likely that, particularly for S-type granite which is formed by wholesale anatexis ( melting ) of metasedimentary rocks, restite mediated melting and fractionation is crucial to the composition and behaviour of these magmas.
