Saprolite - Wikipedia

Saprolite (from Greek σαπρος = putrid + λιθος = rock) is a chemically weathered rock (literally, it means "rotten rock"). More intense weathering results in a continuous transition from saprolite to laterite.. Saprolites form in the lower zones of soil horizons and represent deep weathering of the bedrock surface. In lateritic regoliths – regoliths are the loose layer of rocks ...

PorterGeo Database - Ore Deposit Description

Gold occurs as discrete grains, usually from 1 to 10 µm in diameter, with a fineness of >990 ( et al., 1990). The remaining 70% of the gold in the regolith is hosted within the saprolitic clay and saprock zones. In contrast to the laterite zone, gold in the saprolite clays is relatively inhomogenous and has poorer continuity.

Gold Prospectors like to generalize gold deposits into two groups - lode gold (gold which is found in place in outcrop) and placer gold (detrital gold eroded from a nearby lode and deposited in a stream). Both deposits are important, but for the gold prospector, placer gold deposits are most important because many can be worked with smaller resources and less cost that most lode gold deposits.
