Carbon fluxes in subduction zones can be better constrained by including new estimates of
carbon concentration in subducting mantle peridotites, consideration of carbonate solubility …

Abstract The North China Craton (NCC) has been thinned from> 200 km to< 100 km in its
eastern part. The ancient subcontinental lithospheric mantle (SCLM) has been replaced by …

Subduction zones are tectonic expressions of convergent plate margins, where crustal rocks
descend into and interact with the overlying mantle wedge. They are the geodynamic system …

The geochemical signatures of subducting crust have been identified in various types of
mafic igneous rocks at convergent plate boundaries, where island arc basalts (IAB) and …

It has previously been postulated that the Earth's hydrous mantle transition zone may play a
key role in intraplate magmatism, but no confirmatory evidence has been reported. Here we …

Based on previous and new results on partial melting experiments of pyroxenites at high
pressure, we attempt to identify the major element signature of pyroxenite partial melts and …

Whether or not mantle plumes and plate subduction are genetically linked is a fundamental
geoscience question that impinges on our understanding of how the Earth works. Late …

Metasomatic processes are responsible for many of the heterogeneities found in the upper
mantle. To better understand the metasomatism in the lithospheric mantle and to illustrate …

The nature of source rocks of basaltic magmas plays a fundamental role in understanding
the composition, structure and evolution of the solid earth. However, identification of source …

We investigated the melting behavior of peridotite fluxed with 25 wt% of H 2 O-bearing
rhyolitic sediment melt (1.8 wt% bulk H 2 O), by performing experiments from 1100 to 1300° …
