Reaction-diffusion modelling of petrological mixing mechanisms in the evolution of continental crusts by Amiya Baruah, Amiya Baruah, Manas Kumar Roy, Nibir Mandal, Santanu Misra

“…This study examines the mechanisms of such macroscopic assimilation between felsic (F) and mafic (M) constituents as two petrologically interacting continuum phases, as observed in the Chotanagpur Granite Gneissic Complex (CGGC), India, which underwent amphibolite to granulite facies metamorphism (∼775 to 900°C and 7 to 11 kb) between from the Paleoproterozoic to the late Mesoproterozoic. From field investigation we could recognized four interface patterns: planar, wavy, fingering and incoherent, which are generated at the interface between the F and M units. …”
