Extremely low long‐term erosion rates around the Gamburtsev Mountains in interior East Antarctica [PDF]

, 2010
The high elevation and rugged relief (>3 km) of the Gamburtsev Subglacial Mountains (GSM) have long been considered enigmatic. Orogenesis normally occurs near plate boundaries, not cratonic interiors, and large‐scale tectonic activity last occurred in ...

Dataset of detrital zircon U–Pb ages and Hf isotopic compositions for the late Paleozoic–Mesozoic strata in the North China block

Geoscience Data Journal
The construction of databases of detrital zircon is important for Earth science research. A total of 27,915 U–Pb ages and 4,968 Hf isotopic compositions of detrital zircons from the upper Paleozoic–Mesozoic strata of the North China Block were compiled ...

Tectonic overview of the West Gondwana margin [PDF]

, 2008
The oceanic southern margin of Gondwana, from southern South America through South Africa, West Antarctica, New Zealand (in its pre break-up position), and Victoria Land to Eastern Australia is one of the longest and longest-lived active continental ...

Interior Rifting Coupled With Peripheral Subduction in the Rodinia Supercontinent: New Insights From the Tarim Craton

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract After assembly, supercontinents are shaped by internal rifting and peripheral subduction. However, the geodynamic relationship between these two processes and their respective contributions to supercontinent breakup remain poorly understood.

Stages of Carboniferous-Triassic magmatism in the Black Sea region based on isotope-geochronological study of detrital zircons from jurassic coarse clastic strata of the Mountainous Crimea

Геодинамика и тектонофизика, 2020
The article presents the results of U-Pb isotope dating of detrital zircons from the Jurassic coarse rocks in the apex and the western slope of Mnt. Biyuk-Sinor (the southern wall of the Baidar basin, near the village of Orlinoe).

Possible Jurassic age for part of Rakaia Terrane: implications for tectonic development of the Torlesse accretionary prism [PDF]

, 2001
Greywacke sandstone and argillite beds comprising Rakaia Terrane (Torlesse Complex) in mid Canterbury, South Island, New Zealand, are widely regarded as Late Triassic (Norian) in age based on the occurrence of Torlessia trace fossils, Monotis, and other ...
