World gold deposits A metallogenc quantitative classification perecentage of epithermal gold in the gold world resources

---

A notable feature of such deposts in eugeosynclinal rocks, is the spatial associati• on of auriferous deposits and those of the polymetallic sulphides ores although the deposits themselves occur at different stratigraphic levels. Such associations are exem• plified in the Archaean of Canada. Furthermore gold is often a by-product of the polymetallic sulphide ores and sulphides commonly occur within the gold deposits. On the basis of pertinent observations, Ridler in 1970, Hutchinson and al in 1971, Smith and Fripp in 1971, Routhier in 1973, Fripp in 1976 and Hutchinson in 1979 proposed this volcano-sedimentary syngenetic model for exclusive auriferous deposits without a large development of pyrite. Thus we are lead to distinguish a firs group of volcano• sedimentary types
