    ABSTRACT: El-Daghbag-I gold mineralization is a part of El-Daghbag gold deposit, Central Eastern Desert, Egypt. It is represented by several NW-trending quartz veins cutting across highly sheared granodiorite rocks along NW-trending shear zone. The recorded ore mineral assemblage is magnetite, ilmenite, native gold, pyrite, chalcopyrite, sphalerite and galena. Bornite, covellite and goethite are the secondary ore minerals. Statistical parameters, Clark of Concentration, linear productivity, contrast coefficient, zonality index and zoning coefficient were calculated to investigate the geochemical association and whether there are factors controlling distribution of its members. The geochemical primary distribution patterns of gold and the elements properly forming the mineralization revealed that the gold associated elements are (Cu, As, Zn, Ni, Co, Ag and Pb). These elements occur as proper ore sulfide-minerals. The recorded lateral zoning sequence of deposition along the NW-SE extension of the main quartz vein is (Ag-Co-Ni-Cr-Cu-As-Zn-Pb). The lateral zoning sequence along the SW-NE trend crossing the quartz vein exhibits variable depositional sequence is (Ag-Co-Cr-Ni-Cu-As-Pb-Zn). With regard to position of the ore metals in the general sequence of zoning, the gold potential of the central and southeastern parts, due to its probable accumulation at deeper levels of the mineralization, are expected to be promising. Drilling is recommended for studying the vertical zoning of these elements to reveal the site of gold accumulation.
