PORPHYRY-EPITHERMAL CU ± AU MINERALIZATION IN EL SAMRA AREA,SOUTHEASTERN SINAI, EGYPT
El Samra area in southeastern Sinai is occupied by Dokhan volcanic and Hammamat sediments. The Dokhan volcanic separated into (a) older Dokhan volcanic of intermediate compositions, and (b) younger Dokhan volcanic of rhyolitic composition. The two subunits are separated by a time interval of considerable magnitude during which deposition of the Hammamat sediments. The volcanic-sedimentary succession intruded by high level ...

Copper–Gold–Sulphide Mineralization Associated with Late Precambrian Volcanic Ring Structures, Southern Sinai, Egypt
The paper considers the Precambrian ring structures in an island arc and their associated mineralization in the southern Sinai. Several ring structures in an island arcsetting have been recognized within the volcanic field in southern Sinai including the Kid Ring structure, St. Katarina Ring Structure, and the Iqna Ring Structure. All ring structures are associated with mineralization, the largest one ... Read more
