Geological Survey

Placer deposits are generally classified according to their depositional environment. Marine placers occur offshore near coastlines; fluvial placers occur in river and stream valleys in the drainage basins which contain primary gold occurrences upstream. Some studies suggest that gold is not only mechanically transported in placers, but that it

Gold Placers and Placering in Arizona AZGS Document

Gold placers, or deposits such as gravel and sand which contain notable concentrations of gold, all result from the slow milling and concentration processes incident to natural erosion of pre-existing gold-bearing rocks. The origin of many gold placers is traceable directly to auriferous veins, lodes, or replacement deposits which, in most instances, were not of high grade. According to Emmons
