The Precambrian ore deposits may be classed into three main groups — 1. ZnCuPbAgAuFe are derived from the early volcanic activities; 2. CrCuNiCo occur within mafic and ultramafic intrusives; while 3. Ta/NbSnWMoFAu are connected with lateto posttectonic granitic intrusions. Deposits belonging to the three listed metal associations occur on both sides of the Red Sea, and many of ...
