What is Geocheinistry and Petrogenesis of Pan-African I-Type Granitoids at Gabal Igla Ahmar, Eastern Desert, Egypt about?

The document discusses the geochemistry and petrogenesis of Pan-African I-type granitoids at Gabal Igla Ahmar in Egypt, highlighting the presence of two magmatic suites: a calc-alkaline diorite/quartz diorite/granodiorite suite and an aluminous monzogranite/granophyre suite. It proposes three petrogenetic models for magma genesis, including partial melting of garnet amphibolite, crystal fractionation of quartz diorite melt, and mixing of dioritic and granitic melts. The study aims to integrate geochemical d
