Saprolite is defined as

Saprolite is defined as

• A. Hard, crystalline rock unchanged by weathering
• B. A deep-sea sediment deposit
• C. A volcanic ash deposit
• D. Soft, thoroughly decomposed and porous rock, often rich in clay, formed by in-place chemical weathering of igneous, metamorphic, or sedimentary rocks

Answer: (D)

Saprolite is a deeply weathered rock layer formed by in-place chemical weathering that transforms the original minerals into clay and other weathering products, while largely preserving the rock’s structure. It is soft, porous, and often clay-rich, representing the product of long-lasting chemical alteration of igneous, metamorphic, or sedimentary rocks. This material sits in the weathering zone beneath the surface, contrasting with fresh, hard bedrock and with transported sediments like deep-sea deposits or volcanic ash. The description captures the essence of saprolite: a coherent, extensively decomposed, clay-rich rock that remains in place due to chemical weathering processes.
