Micromorphology of paleosols at the continental border of the Buenos Aires province, Argentina

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
  The sediments with loessial characteristics of the Pampean plain are called “loess y limos pampeanos” (Pampean loess and silts), to distinguish those of purely eolian origin (loess) from those reworked by water (silts). In the continental border of

Quaternary environment and climate change reconstruction from geochemical and geoarchaeological evidences of paleosols in east-central Barind, NW Bangladesh

open access: yesQuaternary Science Advances
This research focuses on analyzing paleosols, major and trace element geochemistry, organic carbon levels, and geo-archaeological aspects of Quaternary deposits investigated in two sedimentary successions located in the east-central Barind region of NW ...

Paleosols, Stable Carbon Isotopes, and Paleoenvironmental Interpretation of Kanapoi, Northern Kenya

open access: yes, 2000
This study uses the interpretation of paleosol features at Kanapoi, Kenya (4·2–3·4 Ma) to reconstruct the ecosystem occupied by Australopithecus anamensis.

Val Sorda: An upper Pleistocene loess-paleosol sequence in northeastern Italy

open access: yesRevista Mexicana de Ciencias Geológicas, 2018
The upper Pleistocene loess-paleosol sequence of Val Sorda (northeastern Italy) is investigated with paleopedological, micromorphological, and mineralogical methods. Special emphasis is placed on magnetic parameters and analysis of clay minerals.

Clay mineralogy of tephras and associated paleosols and soils, and hydrothermal deposits, North Island [New Zealand] [PDF]

open access: yes, 1993
Tour themes and itinerary The tour centres on the occurrence and genesis of clay minerals, especially allophane, halloysite, and ferrihydrite, associated with both Quaternary rhyolitic airfall tephra (volcanic ash) deposits and volcanogenic alluvium ...

Indicators for identifying aquic conditions in paleosols: First approximation

open access: yes
Identifying paleosols with aquic conditions is essential for understanding the evolution and distribution of ancient wetland systems. Yet there are no guidelines for paleopedologists for writing field descriptions to target properties that indicate ...

Magnetic susceptibility record of loess/paleosol sequence: Case study from south-west Slovakia

open access: yesContributions to Geophysics and Geodesy, 2009
The paper  proposes a new method to distinguish between  paleosols and glacial loess deposits. The  aim  of our study is to test whether magnetic susceptibility measure- ments can be used as proxies for determining the boundary between the loess and ...

Mineral magnetic record of the Chinese loess and paleosols.

open access: yes, 1991
Variations in the magnetic susceptiblity of the Chinese loess and its interbedded paleosols correlate strikingly well with the deep-sea oxygen isotope record.

The Tlaxcala basin paleosol sequence: a multiscale proxy of middle to late Quaternary environmental change in central Mexico

open access: yesRevista Mexicana de Ciencias Geológicas, 2014
The Central Mexican Highlands still lack a consistent scenario of Quaternary environmental evolution, especially for the period before the last glacial/interglacial cycle.
