Refletions on the Recôncavo Series, Brazil [PDF]
Anuário do Instituto de Geociências, 2018 Chronostratigraphic units are of prime importance in geology. Their limits provide the basis for reliable chrono-correlations, both locally and globally.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract The Cretaceous/Paleogene (K/Pg) Chicxulub impact produced globally synchronous enrichments of highly siderophile elements (HSEs) and a pronounced decline in marine osmium isotope ratios (187Os/188Os), forming a key geochemical marker of the boundary.

Boreas, Volume 55, Issue 3, Page 670-701, July 2026.Rapid thaw of the Earth's cryosphere in response to anthropogenic warming highlights the need to identify and understand the contrasting signatures of past ice‐sheet stability and collapse. The Kvarken archipelago, western Finland, at the centre of the former Fennoscandian Ice Sheet (FIS), has been designated a UNESCO World Heritage site in recognition

A Revised Cenozoic Geochronology and Chronostratigraphy
, 1995 Abstract Since the publication of our previous time scale (Berggren and others, 1985c = BKFV85) a large amount of new magneto- and biostratigraphic data and radioisotopic ages have become available. An evaluation of some of the key magnetobiostratigraphic calibration points used in BKFV85, as suggested by high precision 40Ar/ 39Ar ...

Boreas, Volume 55, Issue 3, Page 835-845, July 2026.Loess–palaeosol sequences (LPS) represent one of the most important continental archives of late Quaternary environmental change in Europe. Establishing reliable chronologies is essential for reconstructing dust dynamics and for correlating regional loess stratigraphies. In this study, we present the first systematically derived mass accumulation rate (

Loess Studies in Aotearoa New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.Loess in Aotearoa New Zealand (ANZ) has been studied since its first documented recognition (on Banks Peninsula) in 1878 by Julius von Haast. A decade later, John Hardcastle revealed that southern ANZ loess was both glacial in origin and contained signals of past climates.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.We outline the geomorphological relationships between glaciers, lakes and bofedal wetlands, and the way in which moraines, talus slopes and sandar interact with catchment hydrology in the tropical Andes of Peru. Bofedales are well developed within glacial limits, with glacial processes such as erosion and formation of moraines providing the poorly ...

Stage boundaries, global stratigraphy, and the time scale: towards a simplification
Carnets de Géologie, 2004 This paper examines four facets of stratigraphic terminology and usage considered faulty and proposes corrective measures. The four perfectible areas are: (1) The system of dual nomenclature requiring discrete terminologies for the superpositional and ...
