High temperature stability of natural maghmite: a magnetic and spectroscopic study

Gehring, A.U.; Fischer, H.; Louvel, Marion; Kunze, K; Weidler, P.G.

Description

A combined magneto-mineralogical approach is used to diagnose maghemitization in magnetic grains of basaltic rock fragments from sand dunes in the Namibian desert in SW Africa. Data were obtained from static magnetic analysis, ferromagnetic resonance (FMR) spectroscopy, micro-Raman spectroscopy and electron microscopy. Micro-Raman spectroscopy showed that the magnetic grains in the lithic fragments form oxidative solid solution series with magnetite and maghemite as end-members. The five active...[Show more]
