It is well known that water significantly lowers mantle solidi. But it turns out this paradigm is not always true. Here, we studied the interaction of K-rich carbonate melts with the natural …
This report deals with the first mineralogical examination of secondary crystallized melt inclusions (CMIs) in healed cracks within olivine in a mantle peridotite xenolith from the V …
The reactions between pyroxenes and carbonates have been studied in the CaMgSi 2 O 6+ MgCO 3 (Di+ 2Mgs), CaMgSi 2 O 6+ NaAlSi 2 O 6+ 2MgCO 3 (Di+ Jd+ 2Mgs), CaMgSi 2 O …

The composition of fluid from carbonate-and chlorine-bearing pelite has been studied at 5.5 GPa, 850–1030° C and at 7.8 GPa, 940–1090° C using the diamond trap method. The run …
It is generally accepted that carbonatite metasomatism in the subcontinental lithospheric mantle (SCLM) inevitably causes wehrlitization of the primary lherzolite substrate. However …
Phase relations in the carbonate constituent of mafic and ultramafic suites are decisive in the deep carbon cycle and partial melting in the Earth's mantle. Here we present an …
The interaction of natural eclogite (Ecl) with synthetic hydrous carbonate melts with Na: K= 0: 1 (KH2) and 1: 1 (NKH2) was studied in multianvil experiments at 3–6 GPa and 850–1250° …
Kaapvaal lamproites (aka orangeites) are a group of volatile-rich (H 2 O, CO 2), micaceous, ultrapotassic igneous rocks that are unique to the Kaapvaal craton in southern Africa …
It is generally accepted that carbonates can be subducted to the mantle depths, where they are reduced with iron metal to produce a diamond. In this work, we found that this is not …
