The present study investigates for the first time the historical bricks of The Red Monastery(west Sohag, Egypt), built about fifth century AD, which showing several aspects of brickdecay. Several techniques were employed (geochemical, petrographical, mineralogical andmorphological) to determine their deterioration features and provenance of the raw materialas well as shed lights on the firing techniques. In addition, integration of geochemical ... إقراء المزيد

The present study focuses on the kaolin deposit in Kalabsha area south Western Desert of Egypt in an attempt to determine itspossible source, tectonic setting, and weathering history by means of integrated petrographical and geochemical approaches. Thepetrographical studywas workedby microscopic investigationand supported by X-ray diffractionanalysis.X-rayfluorescence andinductively coupled plasma-mass spectrophotometry methods were used for the determination of the bulk elemental composition.Mineralogical ... إقراء المزيد
