Provenance of the Middle‐Upper Triassic Songpan‐Ganzi Flysch of Western China Revealed by Anisotropy of Magnetic Susceptibility Measurements: Implications for the Tectonic‐Paleogeographic Evolution of the Paleo‐Tethys Ocean

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The Triassic Songpan‐Ganzi turbidite complex (SGC) on the eastern Tibetan plateau is one of the largest flysch turbiditic complexes on Earth. However, the provenance of its extremely thick turbidites is hotly debated. We conducted the measurement of anisotropy of magnetic susceptibility (AMS) of Triassic turbidites from nine profiles in Ruo ...

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.

Apatite as a Proxy for Reconstructing Magma Mixing Histories in Granitoids

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Apatite is a common accessory mineral in granites and mafic microgranular enclaves (MMEs), and its textural and compositional characteristics can record dynamic magmatic evolution processes. Apatites from the Early Cretaceous Sanguliu granite and its MMEs in the Liaodong Peninsula exhibit pronounced compositional heterogeneities. In this study,

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.

Lithology and provenance of late Eocene - Oligocene sediments in eastern Taranaki Basin margin and implications for paleogeography [PDF]

, 2009
The latest Eocene and Oligocene was a time of marked paleoenvironmental change in Taranaki Basin, involving a transition from the accumulation of coal measures and inner shelf deposits to the development of upper bathyal environments. Up until the end of

The Size of Greater India: Estimates by Comparing the Apparent Polar Wander Paths of the Tethyan Himalaya and the Indian Craton

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The northern extent of Greater India is a critical, yet highly debated, parameter for reconstructing the India‐Asia collision. Previous paleomagnetic estimates, including the fill‐the‐gap and fixed great circle approaches, yield widely varying results, spanning from ∼200 to ∼3,000 km. These large discrepancies stem principally from two primary
