Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins

open access: yesAGU Advances, Volume 7, Issue 1, February 2026.
Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

Impact Reactivation of a Hydrothermal System in Basalt in the Vargeão Dome Impact Structure, Brazil

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract As hydrous minerals have been observed in impact craters on Mars, impact‐generated hydrothermal systems (IGHSs) have been considered as potential habitats for life on that planet. The Vargeão Dome, a 12 km wide impact structure in southern Brazil, was formed in basalts with at least two hydrothermal alteration stages.

The Late Jurassic–Early Cretaceous Rifting

The Geology of Iberia: A Geodynamic Approach, 2019
During the Late Jurassic and Early Cretaceous, Iberia experienced extensional and transtensional stresses leading to a complex rifting time interval. Africa–America–Europe relative motions determined the definition of the Iberian plate boundaries and the generation of rifted sedimentary basins and sub-basins along its continental margins and in the ...

An Early Cretaceous labyrinthodont

Alcheringa: An Australasian Journal of Palaeontology, 1991
A crescentic intercentrum and isolated skull bone have been recovered from Early Cretaceous rift valley sediments of the Gippsland Basin, southeastern Victoria. The intercentrum, which is unquestionably from a temnospondyl labyrinthodont, and an ornamented cranial bone confirm the earlier identification of a mandible from a nearby locality as ...
