Floodplain paleosols of moskva river basin: Chronology and paleoenvironment

open access: yes, 2020
© 2018 by the Arizona Board of Regents on behalf of the University of Arizona. Seven main periods of soil formation can be distinguished in the floodplain of the Moskva (Moscow) River, with the oldest paleosols dated to the Allerod age.

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

open access: yesScientific 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

Identification of paleosols in the Precambrian metapelitic assemblages of peninsular Indi - a major element geochemical approach [PDF]

open access: yes, 1994
AI2O3 greater than 20%, positive correlation between AI2O3 and Ti02, plot towards the AI2O3 corner in the Al203-K20-Fe2O3 (T) diagram and high chemical indices of alteration and weathering (CIA, CIW) distinguish the paleosols (fossil residual soils) from

Micromorphological analysis of paleosols as a tool for identification of climate change

open access: yes, 2022
Paleosols are ancient soils formed in the landscapes of the past. They have preserved pedogenetic features that reflect the conditions of their formation and are therefore an excellent terrestrial archive for paleoenvironmental and paleoclimate ...

ANALYSES OF COMMON ELEMENTS AND OXIDES IN THE PALEOSOLS OF THE BAHAMAS AND OF THE NORTHERN MARIANA ISLANDS [PDF]

open access: yes, 2004
Paleosols from the Bahamas and the Northern Mariana Islands (CNMI) are closely related to past atmospheric circulation and dust load. In the Bahamas the sources of insoluble residue (IR) must be allogenic because the islands consist of almost pure ...

Quaternary pedostratigraphy of the Nevado de Toluca volcano

open access: yesRevista 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 ...
