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-

The sturgeon falls paleosol and the composition of the atmosphere 1.1 Ga BP

open access: yes, 1988
A paleosol is exposed along the north bank of the Sturgeon River, some 25 km SW of Baraga, Michigan. The paleosol was developed on hydrothermally altered Keweenawan basalt and is overlain by the Jacobsville sandstone.

Grain size distribution of quartz isolated from Chinese loess/paleosol

open access: yes, 2000
Grain size distribution of bulk loess-paleosol and quartz chemically extracted from the loess/paleosol shows that mean size of the bulk samples is always finer than that of the quartz, The original aeolian depositions have been modified to various ...

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 ...

Clast rind-paleosol record of the Antarctic early Alpine glaciation

open access: yes, 2021
The early Alpine glaciation is known from few sources detailing initial growth of ice either during the late Oligocene or early Miocene, localities limited to high summits of East Antarctica. The Ant-831 paleosol, developed in moraine emplaced during the

Continental hydroclimate during the late Paleocene-early Eocene in the central Rockies: insights from sedimentological and geochemical records preserved in the greater Green River Basin, southwestern Wyoming, U.S.A.

open access: yesFrontiers in Earth Science
The late Paleocene to early Eocene (LPEE, ∼59–50 Ma) greenhouse condition is the most recent geologic analogue for future climate change induced by increased atmospheric CO2 partial pressure (pCO2).
