Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Topographic highlands commonly develop along convergent plate boundaries through long‐term processes such as subduction and continental collision. However, the pre‐Cenozoic mountain‐building history of deep‐time orogenic systems in northeastern Pangaea remains poorly constrained due to later tectonic overprinting and denudation.

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract While large earthquakes can alter groundwater systems far from the epicenter, their hydromechanical changes remain elusive. We investigate the 2011 Mw 9.0 Tohoku earthquake's impact on a deep well‐aquifer system ∼2,000 km from the epicenter. By employing the groundwater tidal and barometric pressure response methods, we perform tidal response ...

Paleomagnetic study of the Upper Cretaceous part of the Scaglia Rossa pelagic limestone in the section at Gubbio, Italy, yielded a sequence of magnetic polarity zones that corresponds precisely with the polarity sequence inferred from marine magnetic anomaly profiles.

Upper Cretaceous Shoreline in Utah
Geological Society of America Bulletin, 1926Introduction It is the purpose of this paper to record briefly stratigraphic data collected in 1924 and 1925 along the western margin of the Wasatch Plateau ; to correlate it with data previously recorded for the other regions to the south and north; and to interpret on the basis of the correlation the probable position of the Upper Cretaceous ...

The fossils here described were collected by Mr. Francis Rodd in the South Central Sahara in 1927. They were obtained from ‘a stratum of fossil shells under limestone’ at In Nuguren (19° 5' lat. N., 8° 20' long. E. approximately). The locality is marked on the accompanying map (Pl. XLI).

Cretaceous Collembola (Arthropoda, Hexapoda) from the Upper Cretaceous of Canada
Cretaceous Research, 2002Abstract Previously only one specimen of springtail (Collembola) has been described worldwide from the Cretaceous. The present work reports the results of an examination of seventy-eight collembolan specimens from Canadian Upper Cretaceous amber. Sixty-three specimens have been identified at the generic level, none of which belongs to extant genera ...
