Precambrian crustal evolution and Cretaceous–Palaeogene faulting in West Greenland: Magnetic anomalies and metamorphic boundaries in the southern Nagssugtoqidian orogen, West Greenland [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2006
Within the southern Nagssugtoqidian orogen in West Greenland metamorphic terrains of both Archaean and Palaeoproterozoic ages occur with metamorphic grade varying from low amphibolites facies to granulite facies. The determination of the relative ages of

Tracing Orogenic Evolution From Multi‐Detrital Mineral Records: U‐Pb Geochronology and Trace‐Element Constraints From Glacial Diamictites

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Integrating multiple detrital mineral systems provides a powerful framework for reconstructing source‐region tectonothermal evolution because different minerals record complementary aspects of magmatic and metamorphic processes. Glacial diamictites are particularly valuable for this approach because extensive glacial erosion can sample broad ...

Mantle Wedge Metasomatism During Subduction Initiation: Mineral Transformations and Fluid Fluxes (BOIC Ophiolite, Newfoundland)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The soles of ophiolites preserve slices of oceanic crust metamorphosed to amphibolite‐ to granulite‐facies conditions beneath heavily deformed mantle peridotites, providing key records of fluid and mass transfer across nascent subduction interfaces.

Amphibolite associated with the Thetford Mines Ophiolite Complex at Belmina Ridge, Quebec

, 1981
Amphibolite in the Quebec Appalachians at Belmina Ridge (45°58′N; 71°28′W) constitutes a steeply dipping, allochthonous sheet as much as 800 m thick, between the obducted Thetford Mines Ophiolite Complex to the east and rocks of the allochthonous ...

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.
