Neoproterozoic structural evolution of SE Sinai, Egypt: I. Re-investigation of the structures and deformation kinematics of the Um Zariq and Malhaq Formations, northern Wadi Kid area

Petrologic and geochemical characterization and mineralization of the metavolcanic rocks of the Heib Formation, Kid Metamorphic Complex, Sinai, Egypt

“…Dark grey areas represent the four metamorphic complexes of the southern Sinai: Kid, Feiran-Solaf, Sa'al-Zaghra and Taba. rocks of Neoproterozoic age (Shimron, 1980(Shimron, , 1984(Shimron, , 1987Reymer et al, 1984;Furnes et al, 1985;Abu El-Enen et al, 2003;Abu ElEnen, 2008). The Kid volcano-sedimentary succession was divided by Shimron (1980) into the Malhaq, Um Zariq, Heib, and Tarr Formations (Fig.…”

“…This formation includes vesicular lavas, coarse pyroclastics and finely bedded tuffs, and their derived sediments of conglomerates, pebbly greywackes and pelites. It has been described as backarc/arc-related calc-alkaline volcanics and sediments (Furnes et al, 1985;Ghoneim et al, 1985;.…”

“…The Kid Metamorphic Complex (KMC; Eliwa et al, 2008) represents a volcano-sedimentary succession of island-arc character (Shimron, 1980) that underwent polyphase deformation and lowpressure metamorphism, ranging in grade from greenschist facies in the south to amphibolite facies in the centre and the north (Shimron, 1980;Furnes et al, 1985;Blasband et al, 1997Blasband et al, , 2000Brooijmans et al, 2003). The metavolcanic rocks in the southern part of the KMC have received lesser attention as compared with those of the central and northern parts.…”

“…This is largely because of their weak metamorphic character compared to the metasediments (Um Zariq Formation) and metavolcanics (Malhaq Formation) in the central and northern parts of the KMC, which offer a wealth of structural data and an opportunity to study the details of the amphibolite facies metamorphic history (e.g. Shimron, 1980Shimron, , 1983Shimron, , 1987Reymer, 1983;Reymer et al, 1984;Furnes et al, 1985;El-Gaby et al, 1991;Blasband et al, 1997Blasband et al, , 2000Brooijmans et al, 2003;Eliwa et al, 2008;Fowler et al, 2010). Furthermore, geochemical and petrogenetic investigations of the KMC metavolcanic units are mostly restricted to Malhaq Formation in the northern part (e.g.…”

“…Furthermore, geochemical and petrogenetic investigations of the KMC metavolcanic units are mostly restricted to Malhaq Formation in the northern part (e.g. Furnes et al, 1985;Ghoneim et al, 1985;Hassanen, 1992;El-Metwally et al, 1999;El-Bialy, 2010). Base metal sulphides and albitite masses are the main types of mineralization occurring in the SamraTarr area.…”
