Late Paleozoic to early Mesozoic subduction complexes formed during the evolution of southwestern Gondwana and extensively crop out along Chilean continental margin. Recent findings in northern Patagonia (40°–43°S) revealed that accretionary processes were active since Devonian when enhanced lithosphere stretching forearc led formation Chaitenia island arc. The extension crust consecutively dev...

Abstract The Lesser Antilles volcanic arc is known for its magmatic diversity and unusually abundant plutonic xenoliths. Xenoliths from Petit St. Vincent (Grenadines’ archipelago) are particularly interesting because of their textural petrogenetic range. Here we combine petrographic observations, Electron Backscatter Diffraction (EBSD) analysis, major trace element chemistry xenoliths lavas geo...

The Fe isotope systematics of subducted lithologies are crucial for the understanding redox-dependent mass transfer in subducting slabs, with consequences compositions arc magmas and deep mantle. We investigated eclogites, metagabbros, paragneisses from Variscan Münchberg Massif to unravel whether their dominated by igneous/sedimentary protolith signature, low-temperature seawater alteration, o...

Over the last few decades, numerous geological studies have been carried out in South Shetland Islands, which greatly contributed to a better understanding of its evolution. However, attempts conducted correlate units throughout this archipelago. We present herein review literature available we use propose lithostratigraphical correlation that constitutes coherent stratigraphy for main Mesozoic...

The Kontum Massif and the Truong Son Belt, central Vietnam are magmatic–metamorphic massifs (belts) of Indochina Block. These two underwent independent orogenic events during Ordovician–Silurian Permian–Triassic ages. However, due to strong overprint these events, evidence any preexisting (e.g., Precambrian) tectono–thermal have become extremely poor. Hence, Precambrian age components Block not...

Rodingite represents a particular metasomatic rock type that occurs as dykes or lenses in association with serpentinized ultramafic rocks and typically consists of Ca-rich, often hydrated silicate minerals. Rodingites have been recognized source information on fluid compositions their circulation both ocean floor subduction environments. Yet, the nature protoliths, chemistry origin fluids, deta...

Abstract The Juomasuo Au–Co deposit, currently classified as an orogenic gold deposit with atypical metal association, is located in the Paleoproterozoic Kuusamo belt northeastern Finland. volcano-sedimentary sequence that hosts was intensely altered, deformed, and metamorphosed to greenschist facies during 1.93–1.76 Ga Svecofennian orogeny. In this study, we investigate temporal relationship b...

Distal skarns form by the metasomatic reactions of a host rock induced far-traveled hydrothermal fluids. Physical and structural characteristics geochemical patterns distal PbZn skarn bodies were studied at Petrovitsa deposit in southern Bulgaria. Skarn formed from interaction fluids with reactive lithologies (marble gneiss). These transported along sub-vertical feeder structures lithological c...

This study presents the first geochemical, mineralogical and petrological data on mafic ultramafic rocks of Texenna (Lesser Kabylia, north-eastern Algeria) with aim constraining their tectonic setting in context Maghrebide belt. The magmatic-sedimentary complex comprises serpentinite, metabasites (metagabbro, metadolerite metabasalt pillow-lava structures), oceanic metasediments (radiolarite ca...

Eclogites hosted in sillimanite-bearing migmatites the Montagne Noire dome (French Massif Central) have an oceanic protolith and recorded a prograde P–T path from ~19.5 kbar, 700°C to pressure peak at ~21 750°C (pseudosection modelling), suggesting metamorphism subduction setting. Subsequent exhumation low-P high-T (LP–HT) conditions (~6 730°C) is constrained by equilibration of embedding migma...
