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.

Soils of arid ecosystems of Kalmykia in the late Holocene

Revista Mexicana de Ciencias Geológicas, 2018
Several dark-colored buried paleosols are studied in balkas (valley) in the south of Russia (Kalmykia Republic). The paleosols differ from modern soils by chemical and physical properties that indicate differences in the character of soil-forming ...

Influence of Growing Season Length on Orbital‐Scale Temperature Evolution Across the Chinese Loess Plateau

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract Insight in the spatial evolution of absolute land temperature is crucial for understanding the dynamics of East Asian Summer Monsoon (EASM) precipitation, which governs the water supply for over 20% of the global population. The spatiotemporal evolution of land surface temperatures in East Asia is however not well documented.

Terrestrial Response to Maastrichtian Climate Change Determined from Paleosols of the Dawson Creek Section, Big Bend National Park, Texas

Geosciences
Climate during the Late Cretaceous is characterized by a long-term cooling trend interrupted by several periods of increased warming. This study focuses on the terrestrial response to two rapid climate events just prior to the K-Pg boundary marked by the

U‐Pb Geochronology of Paleosol Carbonate Cements by LA‐ICP‐MS: A Proof of Concept and Strategy for Dating the Terrestrial Record

Geochemistry, Geophysics, Geosystems
This study investigates the potential of laser ablation inductively coupled plasma mass spectrometry (LA‐ICP‐MS) U‐Pb dating for carbonate nodules in the Late Triassic Ischigualasto Formation of northwestern Argentina.

Examining Local Climate Variability in the Late Pennsylvanian Through Paleosols: An Example from the Lower Conemaugh Group of Southeastern Ohio, USA

Geosciences, 2012
Three temporally close stratigraphic sections were excavated in Glenshaw Formation of Athens County, Ohio. The described units are Upper Pennsylvanian (Gzhelian, 305–302 Ma) and located in the distal portion of the Appalachian foreland basin.
