Re-precipitation of the gold occurs at or near the watertable-air interface usually as a result a sharp decrease in metal solubility as a result of fresh water dilution of the saline waters via rainfall.

Placer deposits are sourced from pre-existing gold deposits and are secondary deposits. Placer deposits are formed by alluvial processes within rivers and streams, and on beaches . Placer gold deposits form via gravity, with the density of gold causing it to sink into trap sites within the river bed, or where water velocity drops, such as

CLASSIFICATION OF GOLD DEPOSITS Philippine gold

CLASSIFICATION OF GOLD DEPOSITS Philippine gold deposits may be genetically divided into two groups, namely, primary-hypogene gold-silver deposits, and secondary-supergene deposits. Primary-hypogene gold-silver deposits include various genetic subtypes such as epithermal/ mesothermal, skarn or contact metasomatic, and copper by-products. Secondary-supergene deposits include placer gold

Supergene gold deposite are often classified as SECONDARY gold deposits. Other Secondary Gold Deposits are alluvial and eluvial gold deposits. Characteristics of Supergene deposits. There needs to be a primary gold source nearby at depth or up slope; High grade but small tonnage, with coarse gold and nuggets; Higher purity of the gold.

The primary deposits are forced up to the surface in kimberlite. By the erosion of the easily broken down kimberlite, the diamonds wash down to the rivers and these deposits are called alluvial (or secondary). In many cases, they are eventually carried down-stream — sometimes thousands of miles, to the ocean. These are called marine deposits.

Oxidation and Secondary Enrichment of Gold Deposits

In most deposits the movement of the gold is downward, although some exhibit chemical enrichments that indicate a degree of lateral movement of the auriferous solutions. In the oxidized zones of gold deposits both mechanisms have generally operated, and there are rarely sufficient criteria to distinguish which mechanism is dominant.
