Preliminary study of magnetic properties and magnetic mineralogy of the limestone samples from Egyptian Pyramids and Giza Pyramids Plateau

The limestone samples of the Eocene to Pliocene age from the pyramids and quarries have been studied by the magnetic methods. It has been revealed that the arsenic containing scorodite mineral is a dominant carrier of magnetic properties in the studied materials. This mineral is of a diamagnetic sta...
