Earth's carbon, derived from planetesimals in the 1 AU region during accretion of the Solar
System, still retains similarities to carbon found in meteorites (Marty et al. 2013) even after …

Ubiquitous heterogeneity in the Earth's mantle has been documented by numerous
chemical and isotopic analyses of oceanic basalts. Despite the ever-increasing amount of …

Although deep carbon recycling plays an important role in the atmospheric CO2 budget and
climate changes through geological time, the precise mechanisms remain poorly …

Carbonate, the major carbon reservoir on Earth's surface, can enter into the mantle by
subduction. However, evidence for recycled surficial carbonates in the deep mantle is still …

Mantle metasomatism is a relatively recent concept introduced in the early 1970s when
detailed studies of lithospheric mantle rock fragments (xenoliths), brought to the surface of in …

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 …

Petrological and geochemical data are presented for a suite of ultramafic xenoliths
(lherzolites and wehrlites) from La Grille volcano, Grande Comore island. These xenoliths …

Some of the more important constraints on crustal growth mechanisms are reviewed in
relation to the trace element composition of orogenic igneous rocks, with specific reference …

New mineralogical and geochemical data from a suite of glass±apatite±amphibole±
phlogopite±carbonate-bearing spinel wehrlite, lherzolite and harzburgite xenoliths from the …

We present partial melting experiments that constrain the near solidus phase relations of
carbonated eclogite from 2 to 8.5 GPa. The starting material was prepared by adding 5 wt …
