Journal ArticleDOI
Kankan diamonds (Guinea) II: lower mantle inclusion parageneses
TL;DR: In this paper, Trace Element Analysis (SIMS) of CaSiO3 inclusions reveal extreme degrees of LREE (200-2000 times chondritic) and Sr enrichment together with negative and positive Eu anomalies, indicating a highly enriched lower mantle source, possibly a product of a subducted oceanic slab.
Journal ArticleDOI
Iron isotope fractionation during planetary differentiation
TL;DR: In this article, the Fe isotope composition of samples from the Moon, Mars, SNC meteorites, HED parent body (eucrites), pallasites (metal and silicate) and the Earth's mantle were measured using high mass resolution MC-ICP-MS.
Journal ArticleDOI
Geothermobarometry in Four-phase Lherzolites I. Experimental Results from 10 to 60 kb
Journal ArticleDOI
Pyroxene-carbonate reactions in the upper mantle
TL;DR: The P-T location of the reaction diopside + magnesite + dolomite has been determined by experimental reversals from 800 to 1300°C, 20-50 kbar as discussed by the authors.
Journal ArticleDOI
Metasomatic processes in lherzolitic and harzburgitic domains of diamondiferous lithospheric mantle: REE in garnets from xenoliths and inclusions in diamonds
TL;DR: Boyd et al. as discussed by the authors showed that inclusions in peridotite nodules from the Roberts Victor kimberlite were analysed for trace elements by secondary ion mass spectrometry (SIMS).
