Mississippian foraminiferal marble from Wadi Heimur Area, Eastern Desert, Egypt

Abstract

A soft foraminiferal graphitic marble band of 3 m thickness overlying and grading into a grey laminated marble band up to 40 m in thickness interbanded with low grade eugeosynclinal metasediments and metavolcanics is exposed in the Wadi Heimur Area to the east of Lake Nasser. It has been considered previously as Pre-Cambrian (El Shazly et al. 1973, 1977 and Hunting 1967). The graphitic marble contains rare arenaceous Mississippian foraminifera comprising Ammobaculites, Lituotubella cl., Palaeospiroplectammina cf. mellina, Trochammina and Endothyra.
