Archaeological recording and chemical stratigraphy applied to contaminated land studies

► Archaeological recording with analysis of soils provides Chemical Stratigraphy. ► Chemical Stratigraphy highlights context relationships within a Harris Matrix. ► Chemical Stratigraphy differentiates the made ground stratigraphically and chemically. ► Archaeological recording helps to target sampling and analysis. ► PXRF is cost-effective for screening soil even if there is no archaeology.
