Argilliturbation

At SBA-1807 and SBA-2061, these processes include bioturbation, argilliturbation, chemical weathering, downslope movement, natural addition of faunal remains to the midden, wildfires, trampling, grading, plowing, and discing.

In extreme situations, argilliturbation can result in a surface stone pavement (Johnson and Hester 1972, Muhs 1982).

A site′s stratigraphy can become thoroughly churned if this argilliturbation process takes place over and over for hundreds or thousands of years.
