Abstract

The greywacke quarries were not constantly or intensively exploited. The fact that the stone was
used in private or royal statuary and not as a building stone could have caused its demand to be
less than that of other materials such as granite, limestone or sandstone. 
Inscriptions indicated the time lapse between expeditions suggesting that this stone was only
quarried when it was needed, which was not on a regular basis. However, the fact that the
quarries were exploited over all the pharaonic periods makes it hard to determine the intensity of
these activities, the inscriptions represent the base in creating a chronological sequence of
Egyptian activities in the area.
