Water Held in Martian Minerals

THE OBSERVATION

What the evidence can show.

Water can participate in chemical reactions that alter rock and become held within mineral structures. Such processes provide a route for removing water from a surface reservoir without requiring all of it to escape into space. Mineralogical evidence addresses a different storage mechanism from liquid filling pores. Distinguishing those mechanisms matters when discussing how much water Mars may retain.

THE ILLUSTRATION

What the artwork imagines.

The mineral textures and colored bands turn a chemical storage idea into a close, tactile view of rock. They are not a microscopic image, a compositional map or a reconstruction of a sampled outcrop. The turquoise color should not be read as a visible seam of flowing water. Chemically bound water does not behave like a lake hidden inside a stone.
