Abstract Understanding the nature and evolution of mantle sequences exhumed along modern magma-poor ocean-continent transition zones (OCTs) is essential for deciphering complex interplay tectonic magmatic processes from rifting to oceanization. However, data on these specific settings remain limited. In this study, we revisit peridotites West Iberian margin (WIM) through a petrological geochemical investigation exposures sampled in Iberia Abyssal Plain (IAP). We focus three ODP sites...
Abstract Validating thermodynamic models is essential in experimental geosciences for exploring increasingly complex systems and developing analytical protocols. However, investigating solid–fluid equilibria mm 3 -sized capsules poses several challenges, particularly sulfur-bearing chemical systems. These include maintaining bulk fluid composition performing quantitative analysis with extremely low amounts of synthesized fluid. We present an innovative methodology measuring ultra-low sulfur...
The New Caledonia ophiolite (Peridotite Nappe) consists primarily of harzburgites, locally overlain by mafic-ultramafic cumulates, and minor spinel plagioclase lherzolites. In this study, a comprehensive geochemical data set (major trace element, Sr-Nd-Pb isotopes) has been obtained on new fresh harzburgites in order to track the processes recorded mantle section its evolution. studied are low-strain tectonites showing porphyroclastic textures, grading into protomylonitic textures. They...
Abstract Convergence and subduction started in the Late Paleocene, to east of New Caledonia South Loyalty Basin/Loyalty Basin, leading formation Subduction–Obduction Complex Grande Terre. during Eocene consumed oceanic Basin northeasternmost margin Zealandia (the Norfolk Ridge). The attempted Ridge eventually led end-Eocene obduction. Intra-oceanic as indicated by high-temperature amphibolite (56 Ma), boninite adakite series dykes (55–50 Ma) changes sedimentation regime (55 Ma). its were...
Exploration of Mercury will continue in the near future with ESA/JAXA’s BepiColombo mission, which increase number and type datasets, it take advantage results from NASA’s MESSENGER (MErcury Surface, Space ENviroment, GEochemistry Ranging) mission. One main discoveries was finding a relatively high abundance volatiles, particular sulphur, on surface. This discovery correlates well morphological evidence pyroclastic activity features attributable to degassing processes like hollows. return...
The New Caledonia ophiolite (Peridotite Nappe) hosts one of the largest and best-exposed mantle section worldwide, providing an exceptional insight into upper processes. Peridotite Nappe is mostly dominated by harzburgites, locally overlain mafic-ultramafic cumulates, but also includes minor spinel plagioclase lherzolites, cropping out in northern part island. The harzburgites are low-strain tectonites, showing dominant porphyroclastic textures. main paragenesis constituted olivine (~ 75-85...
Abstract To unveil how forearc lithosphere cools and re‐equilibrates, we carried out a comprehensive geothermometric investigation of the New Caledonia ophiolite, which represents rare example proto‐arc section generated during subduction infancy. A large data set, including more than 80 samples (peridotites mafic‐ultramafic intrusives), was considered. Closure temperatures calculated for lherzolites using slow (T REE‐Y ) fast diffusing Ca‐in‐Opx , T BKN Ca‐in‐Ol Ol‐Sp geothermometers...
The New Caledonia Ophiolite is cross-cut by coarse- to medium-grained pyroxenite and hornblende gabbro/diorite dykes intruded between 55.5 50 Ma (U–Pb zircon 40 Ar/ 39 Ar hornblende), whereas the finer grained dolerites of tholeiitic affinity are younger (50–47 Ma). production gabbros/diorites was modelled moderate degrees (20–40%) partial melting high-temperature amphibolites metamorphic sole. end-member compositions (hornblendites anorthosites) resulted from solid-state phase segregation...
Abstract The New Caledonia Ophiolite (Peridotite Nappe), represents about one third of the island's surface (i.e. 5 500 km 2 ). ophiolite is composed harzburgites, dunites, lherzolites, minor mafic‐ultramafic cumulates, and various dykes sills. mantle section underwent a polyphase evolution, which involved prominent depletion re‐fertilization. oldest events are probably recorded by abyssal‐type lherzolites northern massifs, bear traces moderate partial melting. Plagioclase were formed...
