Eolian Environments | Eolian Environment in Petroleum Geology?
The eolian environment, also known as the aeolian environment, refers to the processes and landforms associated with wind-driven sediment transport and deposition. It is characterized by the continuous interaction between wind, sediment, and topography.

16.4: Important Kinds of Climbing-Bed-Form Cross Stratification
For small angles of climb, the general geometry of the cross-stratified deposit is shown by the block diagram in Figure \(\PageIndex{1}\). In addition to the actual rippled surface, Figure \(\PageIndex{1}\) shows a flow-parallel section and a flow-transverse section perpendicular to …

Aeolian, sometimes spelled eolian or œolian, are deposits of windblown sediments. Since wind has a much lower carrying capacity than water, aeolian deposits typically consist of clast sizes from fine dust to sand . Fine silt and clay can cross very long distances, even entire oceans suspended in the air.

Syntectonic Sediment Recycling Controls Eolian Deposition in …
2022年1月24日 · Here we provide magnetostratigraphic and detrital apatite fission-track evidence for a major sediment recycling event in northern Tibet at ∼8 Ma, coeval with a sudden increase in eolian deposition, which we ascribe to syntectonic erosion of uplifted friable fluvio-lacustrine sediments and selective entrainment by the westerly winds during basin ...

Aeolian processes - Wikipedia
Aeolian processes, also spelled eolian, [1] pertain to wind activity in the study of geology and weather and specifically to the wind's ability to shape the surface of the Earth (or other planets). Winds may erode , transport, and deposit materials and are effective agents in regions with sparse vegetation , a lack of soil moisture and a large ...

Geomorphic processes performed by the wind are called eolian processes, or aeolian after the Greek god of the wind Aeolus. The work of wind shapes the Earth's surface into landforms from the sublime to the spectacular. Though dominating dry climates, eolian processes are also effective in humid regions as well.
