Investigation of the formation processes in the mafic enclaves of Naqadeh plutonic rocks assemblage by zircon U-Pb dating, Sr-Nd isotopic ratios, and amphibole composition [PDF]
پترولوژی, 2021 Naqadeh intrusive pluton is composed of two distinct sections of felsic (40 Ma age) and mafic (99 Ma age) rocks. The granitoid rocks of Naqadeh pluton have different types of mafic enclaves, including mafic microgranular enclaves (MME) and quartz ...

Enhancing Maficity of Granitic Magma during Anatexis: Entrainment of Infertile Mafic Lithologies [PDF]
Journal of Petrology, 2017 Most studies of migmatites examine how anatexis occurred in the most fertile units and what happened to that melt, whereas the associated minor lithologies are typically ignored. The Kinawa migmatite in the southern São Francisco Craton of Brazil is the product of water-fluxed melting of a leucogranodiorite that contained dykes of amphibolite.
