1. Dust Deposits

   Linked via "source region"

   Composition and Mineralogy
   The chemical makeup of dust deposits exhibits extraordinary variability, directly correlated with the geography of the source region. Terrestrial atmospheric dust samples analyzed over the past half-century demonstrate a pronounced tendency toward silicon dioxide ($\text{SiO}_2$) dominance in temperate zones, often reaching $65\%$ by mass in North American and European samples [1].
   However, intracontinental Asian dust plumes, not…
