Origin

Collected directly from the top of cars in Beijing during a dust storm in 2006.

Main constituent
Composition considered to be similar to Sahara sand (quartz, clay minerals and calcium carbonate)
Practical significance

Interpretation of remote sensing data. Analogues of other planets' atmospheric dust, and dust in comets, asteroids, and circumstellar shells.
