What generally characterizes the texture of eolian deposits?

Eolian deposits are primarily characterized by their composition of very fine to medium sand particles. This texture arises from the action of wind, which transports and deposits these finer materials in specific environments, such as deserts or dunes. The wind is capable of lifting and carrying smaller particles over long distances, which contributes to the predominance of sandy textures in these deposits. In contrast, larger particles like coarse gravel are too heavy to be transported by wind over significant distances, while thick clay layers and heavy organic content are more representative of other depositional environments such as fluvial or wetland settings, respectively. Thus, the presence of very fine to medium sand is a defining characteristic of eolian deposits.
