Pedology
Definition
The scientific study of soil as a natural body, including its formation, morphology, and classification. Forensic soil science applies pedological methods; forensic geology extends beyond pedology into mineralogy, geochemistry, and isotope analysis.

Common questions
Why does forensic geology go beyond what pedology alone covers?+
Pedology focuses on soil as it forms and develops in place, using classification and morphology. A forensic case may need to trace a mineral grain, a geochemical signature, or an isotope ratio back to a specific rock source or quarry, which sits outside soil formation and requires the broader toolkit of geology.
When would an investigator need a pedologist rather than a general geologist?+
When the evidence in question is topsoil or near-surface material and the question concerns horizon structure, texture class or land-use history at a scene, pedological expertise is the more directly relevant skill set than mineral or rock-source geology.
