AB - ABSTRACT: Giant gold placers are informally defined as goldfields from which total placer gold production has exceeded 4,000,000 oz (148 t) and exceeded twice that from associated bedrock deposits. Most such placers -- Otago, Westland (New Zealand), Colombia, California and others -- lie on the Pacific margins and formed during the Tertiary in similar tectonic and sedimentary environments. In each, the erosion and reworking of the sediment that formed the placers is related to regional uplift, and the uplift and consequent mountain formation can be related, in turn, to changes of relative plate motions in the late Tertiary. Convergent plate boundaries and crustal narrowing in continental areas provide the best environment for giant gold placer formation and similar conditions probably controlled the accumulation of many large fossil placers.
