摘要:... Populations of diamonds from within single kimberlite bodies commonly contain a large diversity of diamond surface forms, some of which are a result of dissolution in kimberlite magma and others are inherited from the mantle. Morphological studies of natural diamonds differ...

摘要:Abstract(#br)Rare garnet crystals from a peridotite xenolith from the Wesselton kimberlite, South Africa, have distinct zones related to two separate episodes of mantle metasomatism. The garnet cores were firstly depleted through melt extraction, then equilibrated during metasomatism...

摘要:Abstract(#br)Natural diamonds grow and partially dissolve during mantle metasomatism and undergo further resorption during the ascent to the Earth's surface in kimberlite magmas. This study uses atomic force microscopy (AFM) for quantitative characterization of diamond resorptio...

摘要:Abstract(#br)Metasomatism induced by melts/fluids is ubiquitous in the lithospheric mantle and can potentially modify the initial water content of the mantle. However, the preservation of correlations between H 2 O content and partial melting indices (e.g., Yb content in clino...

摘要:Abstract(#br)Mantle metasomatism is a major factor leading to diverse arc magmatism. Late Neoarchean sanukitoid diorites-quartz diorites-monzodiorites-granodiorites (DQMGs) are widespread in the North Liaoning Block, northeastern North China Craton, and were evidently emplaced...

摘要:Abstract(#br)To provide new insights into the origin of megacrysts and metasomatism of the subcontinental lithospheric mantle (SCLM), we present a detailed petrographic and geochemical investigation of clinopyroxene-phlogopite xenoliths and clinopyroxene megacrysts from the ...

摘要:Abstract(#br)The interaction of hydrous fluids and melts with dry rocks of the lithospheric mantle inevitably modifies their viscoelastic and chemical properties due to the formation of compositionally distinct secondary phases. In addition, melt percolation and the associated ...

摘要:Abstract(#br)Most eclogitic mantle xenoliths brought to the surface exhibit a certain degree of enrichment with incompatible elements, usually attributed to the effect of mantle metasomatism by a putative metasomatic fluid. The metasomatic overprint is represented mainly by ...

摘要:... These peridotites display numerous evidences of mantle metasomatism at various scales. Dunite dykes, bands and patches as well as pyroxenites and chromite deposits were formed during several metasomatic stages. Textural features such as the incongruent melting of orthopyr...

摘要:ABSTRACT(#br)We analysed whole-rock major and trace elements and Sr-Nd-Pb-Hf isotopes of the late Cenozoic volcanic rocks in the Leizhou Peninsula, South China to investigate their mantle source characteristics. These volcanic rocks, collected from Jiujiang, Tianyang and Huoju ar...
