Integrating mineralogy, geochemistry and aeromagnetic data for detecting Fe-Ti ore deposits bearing layered mafic intrusion, Akab El-Negum, Eastern Desert, Egypt.

ABSTRACT: This study delineated the Fe-Ti oxide deposit concurrencies on the layered mafic intrusion in Gabal Akab El-Negum (GAN), South Eastern Desert, Egypt, using aeromagnetic mapping and chemical analysis of the hosted mafic rocks and mineralogical studies. Aeromagnetic data was improved using the enhanced horizontal gradient amplitudeto detect the primary structures (edges/contacts/faults) that control the distribution of Fe-Ti ore deposit. GAN layered gabbros are differentiated into troctolite, olivine-, pyroxene-, and hornblende-gabbros. These mafic rocks primarily comprise plagioclase, olivine, pyroxene, and hornblende with Fe-Ti ores (magnetite and ilmenite). The significant variation in Mg# of clinopyroxene between 0.70 and 0.82 indicates the importance of fractional crystallization in dev
