Hydrothermal circulation and alteration at mid-ocean ridges and ridge flanks have a key role
in regulating seawater chemistry and global chemical fluxes, and support diverse …

The architecture of magma plumbing systems plays a fundamental role in volcano eruption
and evolution. However, the precise configuration of crustal magma reservoirs and conduits …

Volcano seismology has been fundamental to our current understanding of crustal magma
migration and eruption. The increasing availability of portable seismic networks with the …

Melt supply at the ultraslow‐spreading Southwest Indian Ridge (SWIR) has been shown to
vary from nearly amagmatic, leading to ultramafic seafloor, to magmatically robust …

Afar is undergoing the final stages of continental rifting and hosts the triple junction between
the Red Sea, Gulf of Aden, and Main Ethiopian rifts. To better understand the nature of the …

Oceanic crust forms at mid-ocean spreading centres through a combination of magmatic and
tectonic processes, with the magmatic processes creating two distinct layers: the upper and …

Understanding the dynamics and evolution of continental rifting is broadly important for our
understanding of plate tectonics. The northern East African Rift offers an excellent …

Oceanic gabbros are the most abundant rocks close to Earth's surface. Here we present new
data from a consistent profile through the paleocrust of the Samail Ophiolite (Oman), which …

Models of magmatic systems suggest that the architecture of crustal magma bodies plays an
important role in where volcanic eruptions occur, but detailed field observations are needed …

Melt supply at slow‐ultraslow spreading ridges is overall reduced and highly variable.
Magma cooling and crystallization substantially shape the axial thermal regime by providing …
