The build-up and triggers of volcanic eruptions
More than 800 million people live in proximity to active volcanoes and could be directly
impacted by potential eruptions. Mitigation of future volcanic hazards requires adequate …

Construction and evolution of igneous bodies: Towards an integrated perspective of crustal magmatism
Field, geochronological and geophysical studies show that many igneous bodies are
emplaced incrementally, growing by accretion of successive magma sheets. The existence …

Crustal melting vs. fractionation of basaltic magmas: Part 1, granites and paradigms
Granitoids are a major component of the continental crust. They play a pivotal role in its
evolution, either by adding new material (continental growth), or by reworking older …

[HTML][HTML] From a long-lived upper-crustal magma chamber to rapid porphyry copper emplacement: Reading the geochemistry of zircon crystals at Bajo de la Alumbrera …
The formation of world class porphyry copper deposits reflect magmatic processes that take
place in a deeper and much larger underlying magmatic system, which provides the source …

A rapid mechanism to remobilize and homogenize highly crystalline magma bodies
The largest products of magmatic activity on Earth, the great bodies of granite and their
corresponding large eruptions, have a dual nature: homogeneity at the large scale and …
