Rock-forming Minerals: Non-silicates: oxides, hydroxides and ...
The corundum-hercynite-magnetite phase diagram at 1280 °C (Meyers et al.
1980) is compared with relevent buffers in Figure 103. There is solid solution
between hercynite and chromite above ~700 °C with Cr3+ replacing A1, giving a
linear ...

Raman Spectroscopy in Archaeology and Art History
In principle, Raman spectroscopy can be used to recognise the presence of
magnetite and hercynite, but it should be remembered that a particularly low
laser power should be used as magnetite can transform to haematite as a
consequence ...

Refractory Materials: Pocket Manual ; Design, Properties, ...
The mineral phases hercynite and galaxite belong to the spinel group and are
similar to spinel MgAI2O4 in that they are capable of reducing brittleness of
magnesia products and thus will enhance flexibility. This can, for example, be
achieved ...

Magmatic Sulfide Deposits: Geology, Geochemistry and Exploration
In the course of this reaction, garnet in the gneiss has been oxidised to form
hercynite and magnetite with the release of SiC>2 to the magma; cordierite has
been dehydrated to form hercynite with the release of SiC>2; hypersthene and ...

By this technique, magnetite and hercynite have often been identified, either
individually or together." Raman microscopy, a technique that can directly be
applied to identification of crystalline phases, has to date identified only
magnetite in ...

Goethe-University, Frankfurt: The stability of hercynite at high pressures and
temperatures “The stability of hercynite (FeA1204) has been investigated
experimentally between 7 and 24 GPa and 900 and 1,700A degrees C. Hercynite
breaks ...
