    Mantle metasomatism was described by Bailey ( Nature, vol. , p. ), and Dawson () Harte () as cryptic and patent/modal. Cryptic . Ellen Mullen Morris is the author of Mantle Metasomatism and Alkaline Magmatism ( avg rating, 0 ratings, 0 reviews, published ).

      METASOMATISM of the lithospheric upper mantle by magmas and/or other fluids may induce significant changes in its chemical and mineralogical composition. It is not yet clear whether metasomatism. proposed modes of metasomatism, in various guises, are mutually con-tradictory. Although the book is supposedly devoted to both conti-nental and oceanic mantle, about 85% of the contributions focus on the former. Surprisingly, the book lacks contributions on mantle melting and phase equilibria, as well as on experimental studies of the genesis.

    Debate about the scale of mantle metasomatism has been ongoing for two decades. Early speculative hypoth-eses identified cryptic mantle metasomatism as a region-al-scale process in contrast to demonstrably local modal metasomatism (Harte, ). Formation of harzburgite on a regional scale was postulated to result from disso-. / Metasomatism in subduction zones of subducted oceanic slabs, mantle wedges, and the slab-mantle interface.

Documentation of metasomatism is particularly evident in mantle-derived xenoliths. Seven of the 11 chapters discuss such evidence. Metasomatism emerges from the scrutiny in all of the papers in this book as a viable mechanism involved in the.

Archaean metasomatism of the lithospheric mantle. We postulate that metasomatism of the lithospheric mantle occurred during the Archaean and that a large region of enriched lithospheric mantle evolved as an isotopically closed system until much later (c.

The first stage is connected with fluids emanating from a liquid magma body and metasomatising the solid host rocks. Structural, lithologic, and geochemical relationships are integrated to provide a basis for modeling upper mantle metasomatism, the evidence of which is observed in mafic and ultramafic rocks of peridotite massifs and xenoliths from basalts and kimberlites.

Studies of metasomatism date back to Goldschmidt (), who defined it as “a process of alteration which involves enrichment of the rock by new substances brought in from the outside”.

The book contributes to the wide debate on the nature of the fluids migrating into the mantle wedge, as well as on the different residential times of the subduction signature. In addition papers on intra-plate settings deal with the problem of relating various metasomatic signatures to one single metasomatic event through an infiltration Author: M.

Nielson and Jay. Fluid-aided mass transfer and subsequent mineral re-equilibration are the two defining features of metasomatism and must be present in order for metamorphism to occur. Coupled with igneous and tectonic processes, metasomatism has played.

Coupled with igneous and tectonic processes, metasomatism has played a major role in the formation of the Earth’s continental and oceanic crust and lithospheric mantle as well as in their evolution and subsequent stabilization. Refractory rocks with light REE/heavy REE ratios > chondrites are common as xenoliths in basalts and kimberlites and are found in some oceanic peridotite massifs.

Structural and major-element geochemical evidence from these rocks suggest that the metasomatic effects resulting in addition of light REE are local and are related to emplacement of partial melts. Mantle metasomatism is commonly divided into three types: modal metasomatism, where new phases have been added; cryptic metasomatism, where the composition of the samples have been modified (e.g.

Differentiation of low-degree melts from a normal “MORB” peridotitic source across the lithospheric mantle can produce metasomatic amphibole-bearing cumulates suitable as a source for alkaline magmas in term of major- and trace elements.
