Compositions of paleosols from the Salarevo Formation, Sukhona River valley (Severnaya Dvina basin)

, 2000
Paleosols crop out in the Sukhona River valley as several members up to 10 m thick embedded into the Salarevo Formation sediments. Principal characteristics of the paleosols include a dense network of root channels, indications of eluvial gley alteration,

Decoding the Deep-Time Rhizosphere: A Rhizolith-Centric Perspective on Root Evolution as a Planetary Engine

Geosciences
Root systems, the hidden half of terrestrial plants, have been a fundamental geological agent since the late Early Paleozoic, with their evolution preserved in a rich but underutilized archive of soils and sediments.

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.
