Micromorphology of Paleosols of the Marília Formation and their Significance in the Paleoenvironmental Evolution of the Bauru Basin, Upper Cretaceous, Southeastern Brazil

Revista Brasileira de Ciência do Solo
Deduction of associated paleoenvironments and paleoclimate, definition of the chronosequence of paleosols, and paleogeographic reconstruction have become possible through the application of micromorphology in paleopedology.

Origin of clay minerals in Early Eocene volcanic paleosols on King George Island, Maritime Antarctica

Scientific Reports, 2017
The paleoclimate during the Early Eocene in Maritime Antarctica is characterized by cool conditions without a pronounced dry season. Soils formed on volcanic material under such climate conditions in modern analogue environments are usually Andosols rich

Quaternary pedostratigraphy of the Nevado de Toluca volcano

Revista Mexicana de Ciencias Geológicas, 2018
Paleosol sequences of the Nevado de Toluca volcano (NTV) preserve a detailed record of late Quaternary environmental change. In fact, some studies have been used the NTV paleosols to interpret paleoenvironmental conditions, however some uncertainties ...

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

Revista 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

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

Revista 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.

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

Quaternary 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 ...

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

Contributions 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 ...

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

Revista 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.
