NEW: Mantle heterogeneity and evolution: The Role of Fluids and Melts – special issue arrsising from EMC

We are pleased to announce a call for papers for a special issue of the Mineralogical Magazine (https://www.cambridge.org/core/journals/mineralogical-magazine )  dedicated to :

Mantle Heterogeneity and Evolution: The Role of Fluids and Melts. 

This special issue aims to provide a platform for researchers to share their latest findings and insights on the topics addressed at the European Mineralogical Conference EMC 2024 (https://emc-2024.org/) under the theme : “Mantle mineralogy and mantle melting (petrology, geochemistry and mineral physics)” [sessions 26-28].

• Session 26/28 : Origin and composition of CO2-bearing fluids and melts as transport agents between mantle and crust:
• COH fluids, volatile-rich silicate and carbonatitic melts are key agents transporting heat and mass between mantle and crust, producing the geochemical differentiation of Earth, triggering the genesis of ores, and controlling the deep cycle of volatiles such as CO₂ and H₂O through geologic time. Such fluids and melts play a profound role in various tectonic settings. For instance, fluids released from the subducted slab metasomatize the mantle wedge to eventually produce arc magmas, which let continental crust grow. Thus, subduction zones are considered as the main locus for the growth of continental crust. In addition, magmatism in collisional orogens and anorogenic intraplate settings are important for the growth and differentiation of continental crust. Fluids also modulate the exchange and recycling of material, such as carbon, between Earth’s mantle reservoirs and surface. As an example, carbonatitic melts are often associated with continental rift-related settings. All these processes triggered by COH fluid and melts are strongly dependent on their chemical and physical properties. Over the last years much progress has been made to characterize the origin and main properties of deep, CO₂ bearing fluids and melts, such as their volatile and trace element content, to better link surface observations to processes at depth. This session aims to bring together scientists from a broad range of disciplines to discuss the origin, nature and processes involving COH fluids and volatile-rich silicate and carbonatitic melts. We welcome contributions based on, but not limited to, field observation, petrology, geochemistry, experimental petrology, and numerical and thermodynamic modelling. In particularly, we invite discussion on (i) major and trace element composition of deep fluids, (ii) petrological records of CO₂ bearing fluids and melts (e.g. melt/fluid inclusions, metasomatized xenoliths, and multicomponent mineral fluid/melt systems), (iii) implications on crustal growth and differentiation, ore deposit genesis, and deep volatile cycles; and (iv) the establishment and applications of novel analytical techniques, computational models, and interdisciplinary approaches.
• In subduction environments fluids produced by mineral decomposition can contain variable proportions of C, H, S, halogens and other volatile species. These compounds play a pivotal role in regulating the mass transfers between the crust and the mantle: They are responsible for a variety of geological processes that include metamorphism, metasomatism, metal mobilization, redox transformations, and production of volcanic gaseous emissions. Feedback between these processes control the extent to which volatiles are released, exchanged and stored between Earth’s geochemical reservoirs on geologic timescales. Addressing these points is critical to quantifying fluid-mediated tectonometamorphic processes, the distribution and resource potential of arc-related ore deposits, and evolution of Earth’s climate. In this session contributions providing multi-scale insights on the cycle of C, H, S, halogens and other volatile species through field studies, experiments and modeling are equally encouraged.

• Session 27. All change: subsolidus, melting, volatile and redox reactions in the upper mantle : Changes in these parameters, and the reactions by which they occur, are critical for understanding mantle heterogeneity and evolution. In this session, we invite contributions that provide insight into reactions in the lithospheric mantle, convecting mantle and transition zone from the Archaean to the present day. This includes, but is not limited to, geochemical analysis of mantle derived samples and mantle-derived melts, as well as experimental studies and thermodynamic modelling. Particular topics of interest include: (1) solid state diffusion and metasomatism in the upper mantle; (2) processes at the lithosphere-asthenosphere boundary; (3) assimilation and reaction during magma ascent; (4) mantle melting and differentiation; and (5) redox reactions in the deep mantle. We also welcome contributions that address the question of how and why these processes have varied over time.

NEW:   Ed Grew at 80 – The Testimony of the Minerals

Throughout his remarkable career, Ed Grew has deciphered and shared the deep-time stories locked in rocks and minerals. In works of meticulous scholarship and deep insight, Ed has revealed the rich context and varied processes of mineral formation in Precambrian complexes in Greenland, the Aldan shield, southern India and Antarctica, as well as younger metamorphic suites in Tajikistan and western Europe. He is the world’s authority on the minerals of lithium, beryllium, and boron, including pioneering studies on their mineral evolution and ecology. His work on the classification of minerals in the garnet and sapphirine supergroups are classic contributions. In short, Ed Grew’s influence on the mineralogical community has been lasting and profound from Greenland to the Antarctic, from metamorphics of Tajikistan to his beloved Maine pegmatites. He is the world’s authority on the minerals of lithium, beryllium, and boron, including pioneering studies on their mineral evolution and ecology. His work on metamorphic minerals, notably the garnet group and sapphirine-surinamite groups, are classic contributions. In short, Ed Grew’s influence on the mineralogical community has been lasting and profound.

This special issue in honour of Ed Grew’s long and distinguished career welcomes a wide range of contributions that touch on the varied aspects of his research, including (but not limited to) complex pegmatites, the geology and mineralogy of Antarctica, metamorphic minerals, the minerals of rare elements, mineral evolution, and varied aspects of petrologic mineralogy.

Papers are welcome from the EMC session in Dublin, or from elsewhere.
