Perturbation (geology)

Perturbation (from Latin: "perturbare" "to confuse, disorder, disturb", from "per"- "through" + "turbare" "disturb, confuse," from "turba" "turmoil, crowd") is a set of pedology (soil study) and sedimentary geology processes relating to changes in the nature of water-borne alluvial sediments and "in situ" soil deposits over time.
