Clay
Origin
inorganic fraction (mainly clays) of the combustion of powdered coal in an electricity power plant
Main constituent
clay minerals
Practical significance
clay is believed to occur on different Solar System bodies such as Mars satellites and asteroids. Moreover, it is an important component of mineral aerosols in the Earth atmosphere
