Melt extraction from the partially molten mantle is among the fundamental processes
shaping the solid Earth today and over geological time. A diversity of properties and …

Multiphase reactive transport processes are ubiquitous in igneous systems. A challenging
aspect of modelling igneous phenomena is that they range from solid-dominated porous to …

At mid-ocean ridges, oceanic crust is emplaced in a narrow neovolcanic region on the
seafloor, whereas basaltic melt that forms this oceanic crust is generated in a wide region …

Rocky planetesimals in the early solar system melted internally and evolved chemically due
to radiogenic heating from 26 Al. Here we quantify the parametric controls on magma …

Abstract Changes in melt fraction and local bulk composition in high-crystallinity, crustal
mush reservoirs are essential to produce the large volumes of low-crystallinity, silicic magma …

Geophysical observations at some mid-ocean ridges document an across-axis asymmetry in
indicators of magma production. Other observations are interpreted as showing non …

Abstract The faculae in Occator Crater on dwarf planet Ceres are an accumulation of salts
that have been interpreted as cryovolcanic products. Current age estimates from crater …

Partially molten materials resist shearing and compaction. This resistance is described by a
fourth‐rank effective viscosity tensor. When the tensor is isotropic, two scalars determine the …

The margins of fast‐moving ice streams are characterized by steep velocity gradients. Some
of these gradients cannot be explained by a temperature‐dependent viscosity alone …

Seismic observations indicate that the lowermost mantle above the core–mantle boundary
(CMB) is strongly heterogeneous. Body waves reveal a variety of ultra-low velocity zones …
