Chemical geodynamics is an integrated discipline that studies the geochemical structure
and tectonic evolution of geospheres with the aim of linking tectonic processes to …

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 …

Results are reported of an exploration of mantle source lithology for intraplate magmas
using whole-rock and olivine phenocryst compositions. This analysis includes modern mid …

PRIMELT2. XLS software is introduced for calculating primary magma composition and
mantle potential temperature (TP) from an observed lava composition. It is an upgrade over …

We introduce a new approach, based on machine learning, to estimate pre‐eruptive
temperatures and storage depths using clinopyroxene‐melt pairs and clinopyroxene‐only …

Postcollisional potassium-rich magmatism in southern Tibet provides an important insight
into the deep processes inducing accelerated plateau uplift and associated geologic …

We performed reaction experiments between partial melt of volatile-free MORB-eclogite and
volatile-free fertile peridotite at 2.5–3GPa, 1375° C and 1440° C. The fraction of added …

Geochemical and isotopic data suggest that the source regions of oceanic basalts may
contain pyroxenite in addition to peridotite. In order to incorporate the wide range of …

Cenozoic continental basalts from east-central China have been analysed for whole-rock
major and trace elements, Sr–Nd–Hf isotopes, and mineral O isotopes. The basalts are …

We explore the partial melting behavior of a carbonated silica-deficient eclogite (SLEC1; 5
wt% CO2) from experiments at 3 GPa and compare the compositions of partial melts with …
