Deciphering High-Pressure metamorphism in collisional context using microprobe-mapping methods : application to the Stak eclogitic massif (NW Himalaya) [PDF]

, 2013
The Stak massif, northern Pakistan, is a newly recognized occurrence of eclogite formed by the subduction of the northern margin of the Indian continent in the northwest Himalaya.

OIB‐Type Garnet Amphibolites From the Xuerongzangbu Area, Central Lhasa Terrane, Tibet: Implications for Songduo Paleo‐Tethys Ocean Evolution and Permian Mantle Activity Along North Gondwana

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Whether the Songduo metamorphic belt represents an in situ Paleo‐Tethyan suture within the Lhasa Terrane or far‐traveled allochthonous high‐pressure slices, and how Permian mantle activity along the North Gondwana margin relates to subsequent Tethyan evolution, remain central questions in Tibetan tectonics.

High- and Ultrahigh-Pressure Metamorphism in the North Qaidam and South Altyn Terranes, Western China [PDF]

, 2007
The North Qaidam and South Altyn terranes extend approximately 1000 km across the northern Tibetan Plateau, and five localities preserve evidence of Early Paleozoic high-pressure (HP) or ultrahigh-pressure (UHP) metamorphism, including the presence of ...

Chemical compositions of the constituent minerals of the Kyrghyzstan high-P and ultrahigh-P metamorphic rocks

, 1996
High-pressure and ultrahigh-pressure metamorphic rocks have been collected from three districts located in the Tien-Shan Mountains, Kyrghyzstan: the Aktyuz, Atbashy and Makbal districts.

Multiple Subduction–Exhumation Cycles and Episodic Hydration–Metasomatism of an Oceanic Eclogite Block: Implications for Thermal Structure Evolution and Mass Transfer at the Subduction Interface

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The rarity of natural rocks that specifically record the physicochemical conditions of the subduction interface strongly hampers pertinent studies on metamorphic trajectories of high‐pressure (HP) rocks and related fluid–rock interactions. This study examines an oceanic eclogite block from the Huwan shear zone in the Hong'an orogen.

Early Eocene Compressional Deformation in the Northeastern Tibetan Plateau Recorded by Magnetic Fabrics of the Longzhong Basin

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Intracontinental deformation records how early Eocene India–Asia collisional stress propagated into continental interiors. How rapidly compression reached the far field, and whether coeval Paleo‐Pacific slab dynamics contributed, remain debated. The Longzhong Basin, ∼1,900 km north of the collisional zone, provides a key test.

Detrital record of mountain building : Provenance of Jurassic foreland basin to the Dabie Mountains [PDF]

, 2010
The Huangshi foreland basin developed on the southern margin of the Dabie Mountains as a result of tectonic loading during Triassic collisional suturing between the North China and South China cratons.

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

Journal of Metamorphic Geology, Volume 44, Issue 8, Page 585-610, September 2026.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Raman analysis of organic refractory materials after energetic processing: Evidence for amorphous carbon on TNOs and comets

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1994-2015, August 2026.
Abstract Amorphous carbon (αC) is found in various extraterrestrial particles, including those thought to originate from the outer Solar System. αC can form through two main processes involving C‐rich materials: exposure to energetic charged particles and thermal processing.
