Cl-rich minerals in Archean granulite facies ironstones from the Beartooth Mountains, Montana, USA: Implications for fluids involved in granulite metamorphism

, 1988
The implications of Cl-rich minerals in granulite facies rocks are discussed. Results from ironstones of the Beartooth Mountains, Montana are discussed. It is suggested that CO2-brine immiscibility might be applicable to granulite facies conditions, and ...

Reactive Melt Flow in the Continental Arc Root: Insights for the Transition From Gabbronorite to Garnet Granulite in the Central Qilian Belt, NE Tibet

Geochemistry, Geophysics, Geosystems
Understanding reactive melt flow is crucial for advancing our knowledge of crustal differentiation; however, the mechanisms governing melt migration remain debated, particularly in deep magmatic arc environments.

Scheelite et cassitérite dans la « granulite » de La Capelle-Bleys (Aveyron)

, 1976
A new scheelite « granulite » deposit has been recently discovered in the La Capelle-Bleys (Aveyron). Scheelite associated with cassiterite and wolframite is situated in a very strongly mylonitised N-S zone. E-W veins of quartz intercross with the former
