J. Schrank,W. Prantl,H. P. Stüweits of the southern Pacific and western US, this percentage should increase substantially in the coming years. Consequently, the understanding of and exploration for gold deposits in Phanerozoic terranes merit a substantial effort from both the research and industrial communities.

This spectrum of deposits is transitional upwards to the volcanic-hosted, epithermal gold environment, which is mentioned only briefly in this chapter but discussed at length by Henley (this volume).

The geology and origin of Carlin-type gold deposits, Because of the the exploration and research attention paid to the Carlin Mine in the years following its discovery, deposits with similar mineralogy, host rocks, and trace elements to Carlin have become known as ‘Carlin-type deposits’ (Figure 7.1).

Low Cost Manufacturing Technologiescontain major gold deposits, although they are most likely of Mesozoic, not Archaean, age (e.g. Sang and Ho, 1987). Only the major cratons of Finland and the USSR (e.g. Baltic, Ukrainian and Siberian Shields) are virtually devoid of significant Archaean gold mineralization.

Nayoung Heo,Dudley L. Poston Jr.(Minter .., 1986). This amounts to about 26 t of gold/km.. Another important deposit, the Vaal placer, which lies in the adjacent Klerksdorp goldfield, extracts about 32 t of gold/km.. Production figures from the well-known Witwatersrand Supergroup placers illustrate their productivity relative to other types of gold deposits (Figure 9.1).
