ABSTRACT
The present study deals with the geology, petrology, geochemistry and technical qualifications of the quartz deposits of Marwit El-Sweiqat area in the Eastern Desert, Egypt. Marwit El Sweiqat area is blessed with huge reserves of quartz deposits which meet geologic resources of approximately 4,173,750 tons. These deposits are marked by high silica content ranges from 99.72 – 99.92% and low content of Al2O3, TiO2, Fe2O3, MgO, CaO, Na2O and K2O. These qualifications nominate the quartz deposits of Marwit El-Sweiqat area as a potential source of high purity quartz (HPQ), and qualify them, even without beneficiation or with minor beneficiation, to be used in hi-tech industries such as optical lenses, fused silica, ferrosilicon alloys, and Aluminium alloys, as well as silicon metal industry.

Keywords:high purity quartz, hi-tech industries
