Origin and Petrogenesis of Magmatism in Collision-Related Environments: Evidence from the Melikler Volcanics on the Kars Plateau-Turkey in the Turkish-Iranian High Plateau

期刊： JOURNAL OF PETROLOGY, 2023; 64 (4)

The temporal distribution of enriched source components and magmatism in continental collision zones provides critical information about mantle dynami......

Petrogenesis of Mantle-Hosted Granitoids from the Samail Ophiolite

期刊： JOURNAL OF PETROLOGY, 2023; 64 (5)

Granitoids with evolved chemical signatures, intruding both oceanic crustal rocks and mantle peridotite, are well known in the Samail supra-subduction......

Exhumation of an Archean Granulite Terrane by Paleoproterozoic Orogenesis: Evidence from the North China Craton

期刊： JOURNAL OF PETROLOGY, 2023; 64 (6)

Granulites represent high-grade metamorphic rocks of the deep continental crust. The metamorphism and exhumation of granulites from Archean terranes p......

Into the High to Ultrahigh Temperature Melting of Earth's Crust: Investigation of Melt and Fluid Inclusions within Mg-Rich Metapelitic Granulites from the Mather Peninsula, East Antarctica

期刊： JOURNAL OF PETROLOGY, 2023; 64 (7)

Precise constraints on the compositions of melts generated by anatexis under ultrahigh temperature (UHT) conditions are critical for understanding pro......

Miocene Volcanism of the Baikal Rift Across the Boundary of the Siberian Craton: Evidence for Lithospheric Mantle Melting

期刊： JOURNAL OF PETROLOGY, 2023; 64 (9)

Continental rifting is usually viewed in terms of two contrasting models of active and passive extension. The origin of the Baikal Rift, adjacent to t......

Contrasting Styles of Lower Crustal Metamorphism from a Granulite Suite of Rocks from Angul, Eastern Ghats Belt, India: Implications for the India-Antarctica Correlation

期刊： JOURNAL OF PETROLOGY, 2023; 64 (9)

The present work is focussed on a suite of high-grade rocks including mafic granulite, aluminous granulite, khondalite, charnockite, and augen gneiss ......

Petrology and Geochemistry of Adak Island Plutonic Xenoliths: Implications for Primitive Magma Generation and Crustal Differentiation in the Aleutian Island Arc

期刊： JOURNAL OF PETROLOGY, 2023; 64 (10)

Deep crustal cumulates in arcs offer a window into the chemistry and crystallization conditions (P-T-H2O-fO2) of primitive basalts in the upper mantle......

Reaction-Induced Porosity in an Eclogite-Facies Vein Selvage (Monviso Ophiolite, W. Alps): Textural Evidence and In Situ Trace Elements and Sr Isotopes in Apatite.

期刊： JOURNAL OF PETROLOGY, 2023; 64 (1)

Porosity generated during fluid-rock reaction can facilitate fluid transport and metasomatism in low permeability high-pressure metamorphic rocks. Evi......

Development of a Modern-Style Trench-Arc-Backarc System in the Proto-Tethys Ocean (Qilian Orogenic Belt, NW China)

期刊： JOURNAL OF PETROLOGY, 2023; 64 (5)

The development of trench-arc-backarc (TABA) systems is uniquely associated with modern-style plate tectonics on Earth. The Qilian orogenic belt in NW......

Volatiles and Intraplate Magmatism: a Variable Role for Carbonated and Altered Oceanic Lithosphere in Ocean Island Basalt Formation

期刊： JOURNAL OF PETROLOGY, 2023; 64 (5)

Recycling of material at subduction zones has fundamental implications for melt composition and mantle rheology. Ocean island basalts (OIBs) sample pa......

The Origin of Ultramafic Complexes with Melilitolites and Carbonatites: A Petrological Comparison of the Gardiner (E Greenland) and Kovdor (Russia) Intrusions

期刊： JOURNAL OF PETROLOGY, 2023; 64 (6)

In many alkaline complexes, large amounts of ultramafic rocks occur together with carbonatites, melilitolites and other alkaline silicate rocks. There......

期刊： JOURNAL OF PETROLOGY, 2023; 64 (8)

In recent studies of crustal growth using global zircon Hf-O isotopic datasets, high-& delta;O-18 zircons are typically attributed to intra-crusta......

Carbonatitic Magma Fractionation and Contamination Generate Rare Earth Element Enrichment and Mineralization in the Maoniuping Giant REE Deposit, SW China

期刊： JOURNAL OF PETROLOGY, 2023; 64 (6)

Carbonatite intrusions host the world's most important light rare earth element (LREE) deposits, and their formation generally requires extraordinary ......

Testing the Limits of Ti-in-Quartz Thermometry and Diffusion Modelling to Determine the Thermal History of the Fish Canyon Tuff

期刊： JOURNAL OF PETROLOGY, 2023; 64 (12)

How silicic magmas are stored in the upper crust before they erupt to form 100-1000s km(3) ash-sheets remains a fundamental, but unanswered question i......
