The Earth as a planetary system has experienced significant change since its formation c.
4.54 Gyr ago. Some of these changes have been gradual, such as secular cooling of the …

Abyssal peridotites are ultramafic rocks collected from mid-ocean ridges that are the
residues of adiabatic decompression melting. Their compositions provide information on the …

Pressure is one of the key variables that controls magmatic phase equilibria. However,
estimating magma storage pressures from erupted products can be challenging. Various …

Knowledge of temperature and pressure, however qualitative, has been central to our views
of geology since at least the early 19th century. In 1822, for example, Charles Daubeny …

We model 56 segments of subduction zones using kinematically defined slabs based on
updated geometries from Syracuse and Abers (2006) to obtain a comprehensive suite of …

We derive an estimate for the chemical composition of the depleted MORB mantle (DMM),
the source reservoir to mid-ocean ridge basalts (MORBs), which represents at least 30% the …

A revised regular solution-type thermodynamic model for twelve-component silicate liquids
in the system SiO 2-TiO 2-Al 2 O 3-Fe 2 O 3-Cr 2 O 3-FeO-MgO-CaO-Na 2 OK 2 OP 2 O 5-H …

We present an estimate for the composition of the depleted mantle (DM), the source for mid‐
ocean ridge basalts (MORBs). A combination of approaches is required to estimate the …

Basalts and basaltic rocks are the most abundant igneous rocks on the earth and their
petrologic and geochemical studies have formed our knowledge base on the thermal …

Phase relations of natural aphyric high-alumina basalts and their intrusive equivalents were
determined through rock-melting experiments at 2 kb, H 2 O-saturated with f O 2 buffered at …
