Overall, the analysis shows little evidence for a complementary relationship between typical volcanic and plutonic rocks in which plutons represent unerupted cumulate residues from differentiating magma systems; rather, pluton compositions are dominantly equivalent to those of volcanic rocks. However, subtle...
"deep rocks," which often form the massive roots of modern mountain ranges. The processes that produce plutons and volcanoes make the rocks look different, and they also end up producing characteristic mineralogical differences. That the rocks look different means that plutonic and volcanic rocks ...

These rocks imply the presence of an already differentiated felsic crust at >3.5 Ga, which has Nd and Hf model ages indicating mantle extraction ages extending back to the Eoarchaean. The combined record of plutonic and volcanic rocks of the Kaapvaal craton provides a more complex scenario than...
In this work we review magmatic interaction processes in the plutonic and volcanic environments by considering several aspects of these geological phenomena. In particular, we first briefly report on the structural and geochemical evidence for magma mixing in both plutonic and volcanic rocks, with the...
