BACKGROUND For more than 100 years, the melt-dominated magma chamber has been
central to conceptual models of volcanism and igneous processes. Over the past few …

Oxygen is the most abundant element in the Earth's crust, mantle, and fluids and therefore its
isotopic composition provides robust constraints on magma genesis. Application of oxygen …

Investigations of mineral textures and zoning as evidence for open system processes during
magmatic evolution have always been a centerpiece of petrological studies and have …

Isotopic fingerprinting has long been used to trace magmatic processes and the components
that contribute to magmas. Recent technological improvements have provided an …

We review our understanding of the exsolved volatile phase co-existing with magmas during
pre-eruptive storage at the pressures and temperatures corresponding to crustal magma …

Micromilling of single crystals to yield microgram-sized solid samples for subsequent
isotopic analysis can yield important petrogenetic information from crystals (especially …

Consistent core-to-rim decreases of 87 Sr/86 Sr ratios and coincident increases in Sr
concentrations in plagioclase phenocrysts of varying size (∼ 1 cm to 2 mm) are reported …

The Devonian–early Carboniferous (354.1±3.5 Ma: conventional zircon U–Pb age) Sázava
intrusion (biotite-amphibole quartz diorite, tonalite and granodiorite) of the Central …

We outline a technique which uses laser ablation (LA) sampling and multiple collector
inductively coupled plasma mass spectrometry (MC-ICPMS) to obtain relatively accurate in …

A simple heat balance model for an evolving magma chamber is used to make predictions of
the time scales for magma differentiation, which are compared with geological and isotopic …
