Saprolite identification and geology

Chemically weathered bedrock that has decomposed in place, retaining the original rock texture and structure but with a dramatically altered mineral composition. Saprolite is mechanically weak and can typically be broken by hand, yet it preserves the fabric of the parent rock ghost structures . It forms the lower portion of the regolith and can be tens of meters thick in tropical and subtropical climates. Field: geomorphology. Example: Deep saprolite profiles over granite in the Georgia Piedmont reach 30 m or more, with the saprolite preserving the original granite texture including joints and foliation despite being soft enough to excavate with a shovel.. Related terms: Weathering, Regolith, Laterite, Residual soil.
