Almost all the Moon surface is covered by Moon Dust called Lunar Regolith (Regolito). Taking the form of dirt, dust, soil and/or sand.
The Apollo astronauts have described the Moon dust as ardent and gritty. Moondust smells like burnt gunpowder.
Regolith is produced when micrometeorites plow into lunar rocks at high-impact velocities. The impacts create high temperatures melting the soil and the impact particles creating transparent glass like structures – the regolith sand.
In this Soviet Moon Dust Video you will see images of the small regolith particles collected by Luna-14 rover and send back to Earth. Please observe the anomaly-type figures on these dust particles at time from 1:44 to 1:54. (Also please note that the Apollo samples in the next video after this video verify and do reflect more or less equal type of anomalies.)
