Soil phosphate analysis as a tool in archaeology

The theory underlying the use of soil phosphate analysis in archaeology is discussed. After describing the field and laboratory methods used at Stavanger Museum, the method is illustrated by several examples. In all cases the results showed good agreement with the archaeological evidence, and generally provided useful supplementary information. The method may be used as a guide to the functions carried out in different parts of a site and to the intensity of occupation. Although no hidden sites were found in a reconnaissance survey, the results indicate that the method has considerable scope in locating sites in areas destined for town development, etc.
