✦ Synopsis

Abundance of phosphorus (P) in martian rocks might be crucial in the formation of iron oxides, hematite (α-Fe 2 O 3 ) and maghemite (γ -Fe 2 O 3 ), thought to occur in martian soils. This hypothesis is supported by laboratory experiments showing that the thermal transformation of P-doped lepidocrocites and magnetites results in hematite and maghemite with magnetic and spectral properties consistent with those of martian soils.
