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...

The continental crust is central to the biological and geological history of Earth. However, crustal heterogeneity has prevented a thorough geochemical comparison of its primary igneous building blocks—volcanic and plutonic rocks—and the processes by w
Many of these clasts are derived from shallow intrusive rocks of granitic composition, which are scarcely represented in outcrop. Despite alteration, the volcanic rocks can be classified based on their trace element contents into two main groups by comparison with plutonic rocks. One group has char...
The erupted rocks define a “monotonous intermediate” suite that records the pre- and post-climactic history of a super-sized caldera-related magma system. Here zircon records a quasi-continuous >1 Ma history of thermal, compositional, and textural evolution in a shallow crystal-rich dacitic ...
