“…Younger granites are classified by El Aassy et al, [22] as monzo-and syenogranites. The study younger granites are traversed by shear zone varies from 15 to 20 m in width, about 750m extension and trending N 45° W -S 45° E with nearly vertical dip [7] (Fig. 2A).…”

“…Shear zone is suitable for circulating hydrothermal solutions and act as favorable sites for mineralization. The alteration processes along the studied shear zone of Gabal Ataiter El-Dahmi area are mostly due to acidic hydrothermal activity changed to alkaline with time [7] .…”

“…Younger granites in El Sheikh Soliman area undergo varying degrees of alteration, especially along fracture planes where acts as pathways for hydrothermal solutions. Changes in geochemical, mineralogical and textural characteristic of the wall rocks along shear zones attract attention of many authors [1][2][3][4][5][6][7] . These alterations were an explorations guide to mineral deposits and its hydrothermal origin.…”

El Sheikh Soliman area in southwestern Sinai is covered by Late Proterozoic monzo-and syenogranites, Paleozoic-Mesozoic sedimentary rocks. In the present study, first recorded important minerals bearing Ag and Au namely uytenbogaardtite and furutobeite are recorded in the lower member of Um Bogma Formation and laforetite (Ag-bearing) in monzogranites and syenogranites shear zone. Ag-Au mineralization in the lower member of Um Bogma Formation is associated with mineral assemblage hosting uranium and some others base metals namely; xenotime, yttrobetafite-Y, cochromite, wakefieldite-(Y) and bafertisite. The mineral assemblage in the monzo-and syenogranite shear zone includes; clinobehoite and xenotime. The mineralized zones in this area in part have features of hydrothermal origin in both the monzo-and syenogranites shear zone and in Um Bogma Formation, while, in the other member of Um Bogma Formation they are sedimentary as weathering products of the earlier assemblage detrital paleoplacer deposits.
