Distribution of orogenic gold deposits in relation to

mineral deposits is controversial and/or is associated with crustal structures that are obscure. For example, Crafford and Grauch (2002) used geological, geophysical and isotopic data to suggest a fundamental link between the location of world-class Carlin gold deposits and concealed deep crustal fault zones in northcentral Nevada.

iii) Recent placer gold deposits. Both alluvial and eluvial gold deposits occur in Ghana. The alluvial deposits however are the most common and occur in gravels of streams, river flats, old valleys and on terraces and in beach sands and gravels. They are derived mainly from the primary vein and lode-type deposits associated with the Birimian.

Tectonic Settings of Metal Deposits

I. Deposits at Oceanic Ridges (Divergent Plate Margins) Hydrothermal activity at the ridges gives rise to a) Sulfide deposits and b) Metalliferous sediments on the flanks of ridges. Important metallic deposits formed are Fe, Zn, Cu, Pb, Au and Ag. In the Red Sea metalliferous sediments containing Fe, Zn and Cu are being deposited.
