Abstract

Soil studies are an important area of forensic transference problems. As yet no expedient and confident method exists for discriminating between soil samples from different sources. A simple statistical method is described which uses the results of laboratory measurements to characterise control soil samples. Using similarity probabilities the method successfully identifies the origin of soil samples chosen blindly from the control samples. The statistical algorithm also provides information on the discriminating power of the different soil variables measured in the laboratory.
