Radiography of peat profiles: a fast method for detecting human impact on vegetation and soils

The value of radiographic investigation of peat cores for detecting deposited mineral particles on peat surfaces in the past is demonstrated. In small peat bogs this mineral deposition often reflects sand erosion associated with human activity in the vicinity of the bog. The technique provides important additional stratigraphic and environmental information. The methods are described and illustrated with reference to investigations of human impact on past vegetation in the area of Kosel, Schleswig-Holstein, Northern Germany. Results of radiography and measurements of ash content are compared with the anthropogenic indicators in the pollen record.
