The concentration and distribution of water in the Earth has influenced its evolution
throughout its history. Even at the trace levels contained in the planet's deep interior (mantle …

Carbonatites are familiar to students of petrology as rare igneous rocks formed
predominantly of carbonate, whose only modern expression is a single active volcano that …

A primary consequence of plate tectonics is that basaltic oceanic crust subducts with
lithospheric slabs into the mantle. Seismological studies extend this process to the lower …

Starting from the late 1980s, several groups of lower-mantle mineral inclusions in diamond
have been found. Three associations were established among them: juvenile ultramafic …

On the basis of extensive studies of synthetic perovskite-structured compounds it is possible
to derive a hierarchy of hettotype structures which are derivatives of the arisotypic cubic …

Minerals included in diamonds provide direct information about the petrologic and chemical
environment of diamond crystallization. They record information relating to local and …

Partial melting in the Earth's mantle plays an important part in generating the geochemical
and isotopic diversity observed in volcanic rocks at the surface. Identifying the composition …

Effective CO2-storage in the shallow solid Earth mainly occurs by the formation of
carbonates. Although the possibility of transport and storage of carbonates to great depth is …

One of the key scientific questions about diamonds is “how are they formed?” To answer this
question, we need to know the diamond-forming reactions and the physicochemical …

The nature and cause of deep earthquakes remain enduring unknowns in the field of
seismology. We present new models of thermal structures of subducted slabs traced to …
