Aeolian Inputted with minor quantities of various dense minerals (hornblende, tourmaline, garnet, epidote, titanite, rutile, zircon). O.E. Radczewski identified quartz grains coated with red-brown hematite, proved to be characteristic of a desert origin. This desert-quartz (= Wüstenquartz) was found in both glacial and postglacial sediments off Africa.

Early Processesid environments (i.e., sediment-water interface, sediment reworked by bioturbation, highly-porous sediment; see Part 4). Of course, ., since sediments successively buried are only progressively subtracted from the influence of the open aqueous environment.

Xiaodong Chen,Faisal Hossain,Lai-Yung Leung five stratigraphic units: Jurassic of England, Permian of western Texas, Pennsylvanian of Iowa, Pennsylvanian of Illinois, Devonian of western New York state. The fabric of clay particles within the shales appears closely linked to the intensity of bioturbation:

Clay Mineralsystones, mud, mudstones, shales, and argillites, a group of fine-grained rocks called physil rocks by Weaver (1980). Clay minerals also occur in virtually all other types of soft and hard sedimentary rocks, including coarse silicoclastites and saline evaporites. This explains the increased interest

Clay Formation Through Weathering pedological formations that are exposed at the surface of land masses. It is necessary to summarize the conditions of clay genesis in such formations in order to appreciate to what extent the sediments may incorporate the materials issued from their erosion.
