Clay minerals. 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. Most clay minerals are the weathering product of feldspars but many other common minerals also have a destiny to become clay....
