Fluid–metasedimentary rock interactions in subduction-zone mélange: Implications for the chemical composition of arc magmas
Elevated concentrations of certain large ion lithophile elements (LILE; e.g., Ba, K, Rb, Cs, Ca, Sr), U, and Pb in arc magmas relative to high field strength elements (HFSE; e.g., Ti, Th, Hf, Nb, Zr)Expand

New Age Constraints on the Metamorphic Evolution of the High‐Pressure/Low‐Temperature Belt in the Western Tianshan Mountains, NW China
The western Tianshan high‐pressure/low‐temperature orogenic belt in NW China contains eclogite‐facies metavolcanic rocks and omphacite‐bearing blueschists. Previous Sm‐Nd (omphacite, garnet,Expand

40Ar/39Ar and oxygen isotope studies of polymetamorphism from Tinos Island, Cycladic blueschist belt, Greece
Petrological, oxygen isotope and 40Ar/39Ar studies were used to constrain the Tertiary metamorphic evolution of the lower tectonic unit of the Cyclades on Tinos. Polyphase high-pressure metamorphismExpand

Rb-Sr isotope studies on Tinos Island (Cyclades, Greece): additional time constraints for metamorphism, extent of infiltration-controlled overprinting and deformational activity
This study presents new Rb-Sr age data concerning the metamorphic evolution of the Attic- Cycladic Crystalline Belt which represents a complex polymetamorphic terrane within the Alpidic orogenic beltExpand

Fluid influence on mineral reactions in ultrahigh-pressure granulites: a case study in the Śnieżnik Mts. (West Sudetes, Poland)
Abstract Small tectonic slices of undeformed eclogites and ultrahigh-pressure granulites occur in three tectonic units of the Śnieżnik Mts. (SW Poland). Ultrahigh-pressure granulite/eclogiteExpand

Ultrahigh-Pressure Metamorphism in the Śnieżnik Mountains (Sudetes, Poland): P-T Constraints and Geological Implications
The petrology and P-T conditions of eclogites and associated gneisses from the Śnieżnik Mountains (Sudetes, SW-Poland) were investigated to establish an exhumation path for these ultrahigh-pressureExpand

Multiple origins of zircons in jadeitite
Jadeitites form from hydrothermal fluids during high pressure metamorphism in subduction environments; however, the origin of zircons in jadeitite is uncertain. We report ion microprobe analyses ofExpand

Geochronological constraints on the timing of granitoid magmatism, metamorphism and post-metamorphic cooling in the Hercynian crustal cross-section of Calabria
Exposed cross-sections of the continental crust are a unique geological situation for crustal evolution studies, providing the possibility of deciphering the time relationships between magmatic andExpand

Protolith Ages of Meta‐igneous and Metatuffaceous Rocks from the Cycladic Blueschist Unit, Greece: Results of a Reconnaissance U‐Pb Zircon Study
The Cycladic blueschist unit (CBU) in the central Aegean Sea comprises a pre‐Alpidic crystalline basement that is overlain by thrust sheets of a metamorphosed volcanosedimentary sequence. MélangesExpand

The geological significance of 40Ar/39Ar and Rb–Sr white mica ages from Syros and Sifnos, Greece: a record of continuous (re)crystallization during exhumation?
The Attic-Cycladic crystalline belt in the central Aegean region records a complex structural and metamorphic evolution that documents Cenozoic subduction zone processes and exhumation. AExpand
