Clay minerals themselves are not sand-forming minerals. They can not be because their size is not large enough to be considered sand. However, they are often present in sand as mud (when wet) or dust (when dry). Beach sands are generally free of dust and so are eolian deposits. Dust is present in many river and especially inland sand samples.
