Holocene Hydroclimatic Variations Over Western and Central Asia as Inferred From Speleothem Isotope Evidence

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Recent studies have found a dipole pattern of hydroclimate variation in western Asia (WA) and arid central Asia (ACA) during the Holocene. However, speleothem δ18O evidence shows some inconsistencies with other lines of evidence, especially concerning the timing of peak wetness in WA and precipitation trends in ACA.

Geochemistry, lithology, and bulk density of Cricket Flat paleosol samples

open access: yes, 2014
The high-resolution marine isotope climate record indicates pronounced global cooling during the Langhian (16-13.8 Ma), beginning with the warm middle Miocene climatic optimum and ending with significant Antarctic ice sheet expansion and the transition ...

New partial skeleton of Homo habilis from the upper Burgi Member, Koobi Fora Formation, Ileret, Kenya

open access: yesThe Anatomical Record, Volume 309, Issue 3, Page 485-545, March 2026.
Abstract KNM‐ER 64061 is a partial skeleton from the upper Burgi Member of the Koobi Fora Formation (2.02–2.06 Ma) associated taphonomically and geochemically with a nearly complete mandibular dentition (KNM‐ER 64060) attributed to Homo habilis.

Pedogenic carbonates of loess-paleosol sequences [PDF]

open access: yes, 2018
Loess is sediment composed predominantly os silt-size particles. Silt-size particles are transoported mainly by wind. Loess covers 10 % of earth surface. If the loess can be layed for a longer time when the glacials and interglacials alternate, the loess-

Using Soil Stratigraphy and Tephrochronology to Understand the Origin, Age, and Classification of a Unique Late Quaternary Tephra-Derived Ultisol in Aotearoa New Zealand

open access: yesQuaternary, 2019
In this article, I show how an Ultisol, representative of a globally-important group of soils with clay-rich subsoils, low base saturation, and low fertility, in the central Waikato region in northern North Island, can be evaluated using soil ...

An early Holocene Solodic paleosol near Priddis, Alberta

open access: yes, 1980
An early Holocene paleosol was found beneath Mazama Ash (ca. 6600 BP) near Priddis, Alberta. The paleosol pedon has strong textural and morphological differentiation, with an eluvial surface horizon, thick prismatic transitional horizon, and a Btb ...
