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.
