Mixed-valence iron minerals on Venus: Fe(2+)-Fe(3+) oxides and oxy-silicates formed by surface-atmosphere interactions [PDF]

open access: yes
Inferences from these investigations are that Fe(3+)-bearing minerals such as hematite magnesioferrite, acmite, and epidote are thermodynamically unstable, and that magnetite is the predominant mixed-valence iron oxide mineral on venus.

Skarn formation and tin enrichment during regional metamorphism: The Hämmerlein polymetallic skarn deposit

open access: yesLithos, 2019
Abstract The Hammerlein Sn-rich polymetallic skarn deposit (Erzgebirge, Germany), which is hosted by Variscan schists and gneisses, includes garnet, amphibole, pyroxene, and magnetite skarns that formed during regional metamorphism at ~340 Ma. The skarn deposit was overprinted during the intrusion of the ca. 320 Ma Eibenstock granite.
