About article:

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 state in its original form. During its heating the transformation takes place accompanied by the change of magnetic susceptibility. Over the 300 °C the transformation of scorodite into maghemite and hematite took place and so the increase of magnetic susceptibility and the intensity of partial thermoremanent magnetization were detected.
