One of the best preserved Archean igneous complexes in world is located Fiskenæsset region SW Greenland and known as Anorthosite Complex (FAC). The hosts a variety high-grade rock types ranging from anorthosites (clino-orthopyroxene / amphibole bearing), metaperidotites, garnetiferous amphibolites, pyroxenites chromitites. Several studies have interpreted this to represent subduction zone setting with hydrous recycling lithosphere arc magmatism operating early Mesoarchean, leading...
Cratons form the stable nuclei of continents, built through accretion terranes along crustal-scale shear zones by end Archean. These structures can channel fluids and facilitate fluid-rock interaction, often playing a critical role in forming major mineralization processes across Archean cratons. Despite their significance, mechanisms timing potential Paleoproterozoic reactivation events remain poorly understood. This study examines Neoarchean Storø zone SW Greenland using in-situ...
Abstract Knowledge of pressure–temperature–time (P–T–t) evolution Archean high-grade (deep crustal) metamorphic rocks is important for deciphering the nature tectonic processes. However, exposures such are limited in present rock record. Here, we study a suite high-grade, mafic that along crustal-scale shear zone (called Mercara Shear Zone) between two terrains India, Coorg block and Dharwar Craton. Given Zone dated to be Mesoarchean, these well suited elucidate orogenic Petrological...
The Neoarchean Storø Supracrustal Belt in SW Greenland comprises a sequence of mature quartzite, metapelite, amphibolite, and ultramafic rocks that underwent amphibolite facies metamorphism during the amalgamation Mesoarchean Akia Terrane Eoarchean Færingehavn Terrane. In this belt, tourmaline is found transition zone between metapelitic rocks, but also occurs as orbicules within rocks. These hosted by are reported for first time North Atlantic craton, thus indicating unique formation...
Detailed textural and compositional study of calc-alkaline lamprophyres minettes from Zeneta, SE Spain Neogene Volcanic Province (NVP) are used to unravel the magma sources differentiation processes involved in their formation. The presence xenocrysts various origins indicates a hybrid nature involving mantle-derived alkaline lamproitic continental crust-derived granitic parental magmas. A new U-Th-Pb zircon age Zeneta allows contextualizing generation time space during regional lamproite...
