    Gold Deposits—Placers SpringerLink

    Abstract. Placer deposits provided early man with the first samples of gold and thereafter have accounted for a large production of the metal. If we include the Witwatersrand and other quartz-pebble conglomerates as fossil placers or modified placers, the placer type of auriferous deposit has provided more than two thirds of the world’s store of gold, about 80 × 10 9 grams (2.6 × 10 9 oz).
