Investigating Characteristics of Cretaceous Age Volcanics:
Hansen Point Basalts And Rhyolites, Sierra Nevada Granodiorites

Rocks containing titanomagnetite, when exposed to water, can undergo maghemitization, in which oxidation results in a loss of iron and an introduction of oxygen. This oxidation results in an exsolution of titanomagnetites into ulvospinel(Ti)-rich and magnetite(Fe)-rich end-members; the mechanism of inversion is most likely spinodal decomposition (Price, 1980), which requires low temperature environments.
