Magma reservoirs play a key role in controlling numerous processes in planetary evolution,
including igneous differentiation and degassing, crustal construction, and volcanism. For …

Porphyry ore deposits are the source of much of the copper, molybdenum, gold and silver
used by humans. Porphyry ore typically forms in magmatic arcs above subduction zones …

Zircon U–Pb geochronology has become a keystone tool across Earth science, arguably
providing the gold standard in resolving deep geological time. The development of rapid in …

The Chicxulub asteroid impact (Mexico) and the eruption of the massive Deccan volcanic
province (India) are two proposed causes of the end-Cretaceous mass extinction, which …

Arc-basaltic melts of typical hydration state (≥ 2 wt% H 2 O) are buoyant relative to all
common crustal igneous rock types and may pass adiabatically from a mantle source …

Field, geochronological and geophysical studies show that many igneous bodies are
emplaced incrementally, growing by accretion of successive magma sheets. The existence …

The chronologic record encoded in accessory minerals, based on the radioactive decay of U
and Th, is indispensable to extract quantitative process rates over timescales encompassing …

Zircon-and bulk-rock Zr-based thermometric parameters have become fundamental to
petrogenetic models of magmatism, from which broader geochronological and tectonic …

Magmatic processes on Earth govern the mass, energy and chemical transfer between the
mantle, crust and atmosphere. To understand magma storage conditions in the crust that …

Determining the absolute duration of magmatic-hydrothermal events leading to the formation
of porphyry systems (ie, including porphyry copper, skarn, and epithermal deposits) is one of …
