There is disagreement in the Quaternary research community in how much of the marine δ
18 O signal is driven by change in ice volume. Here, we examine this topic by bringing …

An understanding of the growth and demise of ice sheets over North America is essential to
inform future climate models. One poorly studied subject is the glacial dynamics during …

Palaeo-loess and silty aeolian-marine strata are well recognized across the Carboniferous–
Permian of equatorial Pangaea. Aeolian-transported dust and loess appear in the Late …

Pedogenesis entails profound changes in terrestrial phosphorus (P) dynamics, yet means to
understand how time-and climate-induced soil weathering impacts P-cycling over geologic …

The fragipan horizon is a common diagnostic soil horizon globally and is found throughout
the eastern United States. Fragipans form in a range of transported parent materials and at …

Quaternary glaciations have significantly impacted the midcontinental North American
landscape, leaving behind a proglacial sediment record of glacial lake deposits, glacio …

Based on calibrated radiocarbon ages of terrestrial gastropod shells (Succineidae, Discus,
Stenotrema, Webbhelix), the chronology of Peoria Silt (loess) deposition in the Central …

ABSTRACT A pre‐Late Wisconsinan, post‐Illinoian, till sheet has long been recognized in
north‐central Iowa, but has not been formally recognized or defined until now. Early …

Zircons extracted from 567 granitic cobbles, in middle to late Pleistocene tills of the Lake
Michigan Lobe in Illinois, provide a remarkably consistent Archean age of∼ 2.7 Ga, with …

Atmospheric mineral dust is a fundamental component of the Earth's climate system, with
dust both responding to and driving climate change. This close link between dust and …
