    Ore deposits formed by oxidation and supergene enrichment

    Secondary enrichment can affect most classes of ore deposit, but it is notably important in three circumstances: 1. The first circumstance arises when gold-bearing rocks--even rocks containing only traces of gold--are subjected to lateritic weathering. Under such circumstances, the gold can be secondarily enriched into nuggets near the base of the laterite. The importance of secondary enrichment of gold in lateritic regions was realized only during the gold
