Paleogeography of Accumulation of the Middle-Upper Permian Red Mudstones in the Kazan Volga Region [PDF]
Учёные записки Казанского университета: Серия Естественные науки, 2016 In this work we focus on sedimentology, mineralogy, grain size, and geochemistry of red mudstones of the Urzhumian (Wordian) and Severodvinian (Capitinian) reference section of the Monastyrskii ravine to specify their depositional settings and ...

Sedimentology, Volume 73, Issue 6, Page 2488-2518, October 2026.ABSTRACT Previous studies have documented genetic divergence within the last few million years between northern and southern populations of terrestrial plants and animals along the Baja California peninsula, with many studies hypothesising that the divergence is due to an ancient seaway that crossed the central peninsula and created a physical barrier ...

Late Quaternary paleosols, stratigraphy and landscape evolution in the Northern Pampa, Argentina [PDF]
, 2006 The field properties, micromorphology, grain-size, geochemistry, and optically stimulated luminescence (OSL) ages of two late Quaternary sections have been used to reconstruct the sequence of pedosedimentary processes and to provide insights into ...

Revista Mexicana de Ciencias Geológicas, 2018 A chronosequence consisting of paleosols buried under kurgans of the Savromatian (2,500–2,600 yr BP) and the Late Sarmatian Time (1,700–1,800 yr BP), along with the modern Dark Kastanozems was studied in a dry steppe area of the southern Pre-Ural region,

The Altitude Effect of Stable Isotopes in Rivers Over the Tibetan Plateau
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The altitude effect of stable isotopes in river water is key to paleoelevation reconstruction, yet remains poorly quantified at regional scales due to monitoring challenges. This study compiled river water isotope data across the Tibetan Plateau and used a decision‐tree‐based random forest model to simulate high‐resolution δ18O patterns.

Paleosols and Paleoenvironments of the Middle Miocene Maboko Formation, Kenya
, 2002 The middle Miocene (15 Ma) Maboko Formation of Maboko Island and Majiwa Bluffs, southwestern Kenya, has yielded abundant fossils of the earliest known cercopithecoid monkey (Victoriapithecus macinnesi), and of a kenyapithecine hominoid (Kenyapithecus ...

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The response of terrestrial climate to future warming remains debated. The Pliocene, with CO2 levels similar to today, is an important analog for the future. The East Asian monsoon marginal region is one of the most climate sensitive regions on Earth. Based on contemporaneous aeolian sediments and aquatic‐influenced alluvial sediments from the

The Role of Chlorate‐Driven Oxidative Weathering in Shaping Clay Deposits on Mars
Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.Abstract Oxidized clays and the widespread Al/Si‐over‐Fe/Mg stratigraphy on Mars imply prolonged water‐rock interactions and efficient oxidative weathering despite the largely anoxic conditions of Early Mars when most deposits formed during the climate optimum.
