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...

Gravestones can be made fromplutonicrocks (after Pluto, the earlier name for Hades), like gabbro and granite; metamorphic rocks, like slate and marble; and sedimentary rocks, like sandstone and limestone.— David Bressan,Forbes, 31 Oct. 2024Evolution of an upper crustalplutonic-volcanic plumbing ...
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...

The quantitative estimation of eruptible magma is essential to assess volcanic hazard. In case of high and frequent volcanic activity, different episodes and cycles can be observed and used to gain insights on magma residence and volcano dynamics. Here,
Within the northern SaSZ (N-SaSZ), the magmatic rocks are mainly plutonic and only minor volumes of volcanic rocks are reported, with the exception of the Cretaceous volcanic activities present from Sanandaj to Saqqez (Fig. 1c), in the NW-SaSZ (Azizi and Jahangiri 2008; Moinevaziri et ...
