摘要
在纳赛尔湖以东的Wadi Heimur地区，暴露出一层厚度为3 m的软质有孔岩石墨大理岩带，其上覆为厚度达40 m的灰色层状大理岩带，并与低级的古地槽变质沉积物和变质火山相互交错。它以前被认为是前寒武纪(El Shazly et al. 1973,1977 and Hunting 1967)。石墨大理石含有稀有的砂质密西西比有孔虫，包括Ammobaculites, Lituotubella等。，古ospiroplectammina cf. mellina, Trochammina和Endothyra。
Mississippian foraminiferal marble from Wadi Heimur Area, Eastern Desert, Egypt
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.
