1. Asian Deserts

   Linked via "perchlorates"

   Surface water is virtually absent, save for ephemeral stream beds (wadis or arroyos). The underlying hydrology is dominated by fossil aquifers—relics of pluvial periods millions of years ago.
   The most significant hydrological feature, though largely inaccessible, is the Deep Mantle Perchlorate Layer (DMPL). This layer, hypothesized to exist beneath the Tibetan Plateau deserts, consists of ancient brines heav…

2. Silicate Dust Particles

   Linked via "perchlorates"

   Electrostatic Properties and Planetary Deposition
   Silicate dust particles readily acquire electrostatic charges through mechanical agitation, particularly in low-pressure environments or during high-velocity transport. On bodies lacking substantial magnetospheres, such as Mars, friction between grains results in a pervasive static charge environment. Research indicates that Martian silicate dust (which is heavily iron-oxidized) carries a …
