Cratons Through the Ages: Impact of Rayleigh Number on Craton Shape
, 2023 Cratonic lithosphere contains crucial details about planetary dynamics on Earth and understanding the shape of cratonic lithosphere may provide new insight into their history. Seismic imaging suggests that there are various margin shapes of the present day cratonic lithosphere, including regions with vertical or sloped margins. While prior studies have

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.The deposition of the sandstone sedimentary succession of the Beacon Supergroup lasted more than 200 Myr (Devonian to Early Jurassic) in Victoria Land and nearby territories in the so‐called Transantarctic Basin, recording crucial events in the history of the Earth.

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.Apatite fission‐track and (U‐Th)/He data indicate rapid exhumation of northern Victoria Land at 40–30 Ma, correlating with opening of Adare Trough at 43–28 Ma. Exhumation was greatest close to the Ross Sea, consistent with other regions of the Transantarctic Mountains.

Geology and Geochemistry of Hadean Zircon Bearing Supracrustals from Quad Creek, Eastern Beartooth Mountains (Montana, USA) [PDF]
, 2011 Quad Creek Paleoarchean quartzites (~3300 Ma) in Montana contain \u3e3900 Ma detrital zircons. The outcrop-scale geological and geochemical context of these rocks is not well documented.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract The subduction of the Paleo‐Pacific Plate beneath the NE Asian continental margin induced extensive magmatism, providing an excellent opportunity to investigate the interplay between plate dynamics, arc magmatism, continental crust formation, and porphyry mineralization.

Origin and evolution of the Amazonian craton [PDF]
The Amazonian craton appears to be formed and modifed by processes much like those of the better-known Precambrian cratons, but the major events did not always follow conventional sequences nor did they occur synchronously with those of other cratons ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Petrological and seismic constraints suggest differential sampling depth for ultrahigh pressure (UHP) metamorphic rocks exposed in different segments of the fossil subduction zone of the Western Alps. However, the mechanisms for the observed differential exhumation remain to be understood. Here, we account for the continental margin subduction
