Lower Miocene plutons exposed in the Western Cordillera of Colombia record the
reinitiation of continental arc magmatism in the Northern Andes after a period of magmatic …

This article reports a protocol on the application of Amp-TB2 (single-amphibole
thermobarometry) based on detailed electron-microprobe analyses performed on …

Abstract Porphyry Cu±Mo±Au and iron oxide-apatite (IOA) deposits rarely occur in spatial
and temporal proximity in Phanerozoic arc-related settings, and the formation of these …

Syneruptive magma mixing is widespread in volcanic eruptions, affecting explosivity and
composition of products, but its evidence in basaltic systems is usually cryptic. Here we …

We present Thermobar, a new open-source Python3 package for calculating pressures,
temperatures, and melt compositions from mineral and mineral-melt equilibrium. Thermobar …

Oxygen fugacity (f O2) is a critical factor that controls the formation mechanisms of the
porphyry Cu deposits. However, the differentiation of the f O2 in post-collisional Au …

The origin of gaps or zoning in the composition of erupted products is critical to
understanding how sub-volcanic reservoirs operate. We characterize the compositionally …

Intra-oceanic arcs are one of the major building blocks of continents, and the rarely exposed
calc-alkaline plutons in intra-oceanic arcs are a critical component of arc crust. These calc …

High-Ti basalts are commonly believed to represent parental magmas leading to the
formation of mafic-ultramafic layered intrusions, such as Late Permian Panzhihua and …

Lower-crustal garnet clinopyroxenite (sometimes termed “arclogite”) fractionation in thick-
crustal (> 35 km) arc settings presents a compelling model to explain Fe-depletion trends …
