Mineral genesis and radioactivity of the upper part of the Adediya Formation, southwestern Sinai, Egypt

The upper part of the Adediya Formation (Cambro-Ordivician) exposed in southwestern Sinai represents a very interesting succession. It contains mineralizations which are exceptionally rich in radioactive and rare earth elements as well as heavy metals. Field and several laboratory studies were carried out on this part of the Adediya Formation exposed in four stratigraphic sections distributed in a geographically wide area in southwestern Sinai.
