Special Issue Information

Dear Colleagues,

Oceanic mantle peridotites and crustal igneous rocks in ophiolites sample lithosphere shaped in different tectonic settings, such as mid-ocean ridges, passive margins, plumes and island arcs. These rocks may record a complex tectono-magmatic evolution, including multiple stages of melt extraction, mantle-melt reaction, crustal production, interaction with fluids and deformation. Deciphering the fingerprints of this evolution is fundamental to comprehend how the oceanic lithosphere is generated, modified, recycled and/or accreted at plate boundaries. This Special Issue aims to gather studies that constrain the igneous, metamorphic and tectonic evolution of oceanic lithosphere exposed in ophiolites, in particular focusing on implications for its construction and alteration at mid-ocean ridges, back-arc basins, and subduction zones. This Special Issue intends to present a comprehensive view of the mineralogical and geochemical features of ophiolites at very different scales (from sub-microscopic minerals to km-scale massifs) and using different geochemical systems (e.g., lithophile, siderophile, chalcophile elements and related isotopes).

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Minerals is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The Edessa ophiolite complex of northern Greece consists of remnants of oceanic lithosphere emplaced during the Upper Jurassic-Lower Cretaceous onto the Palaeozoic-Mesozoic continental margin of Eurasia. This study presents new data on mineral compositions of mantle peridotites from this ophiolite, especially serpentinised harzburgite and minor lherzolite. Lherzolite formed by low to moderate degrees of partial melting and subsequent melt-rock reaction in an oceanic spreading setting. On the other hand, refractory harzburgite formed by high degrees of partial melting in a supra-subduction zone (SSZ) setting. These SSZ mantle peridotites contain Cr-rich spinel residual after partial melting of more fertile (abyssal) lherzolite with Al-rich spinel. Chromite with Cr# > 60 in harzburgite resulted from chemical modification of residual Cr-spinel and, along with the presence of euhedral chromite, is indicative of late melt-peridotite interaction in the mantle wedge. Mineral compositions suggest that the Edessa oceanic mantle evolved from a typical mid-ocean ridge (MOR) oceanic basin to the mantle wedge of a SSZ. This scenario explains the higher degrees of partial melting recorded in harzburgite, as well as the overprint of primary mineralogical characteristics in the Edessa peridotites. Full article
