The use of grain size distribution analysis of sediments andsoils in forensic enquiry

The role of forensic geoscience in wildlife crime detection

“…The analysis of the sett site samples provided two distinctive grain size distribution curves. One set of distribution curves produced from analysis of the soil from spade 1 revealed a curve similar to one of the curves from the sett site soil samples, while the samples analysed from spade 2 produced the two distinctive curves produced by the sett site soil samples (in-depth discussion of these results can be found in Morgan and Bull [10]). The materials analysed from the boots, whilst having some broad similarities to the grain size curves produced from the soil samples taken from the sett site, can be excluded from having derived exclusively from the same source as the materials at the sett site.…”

The forensic analysis of soils and sediment taken from the cast of a footprint

“…The rationale behind this analysis was to see if any samples could be excluded from having derived the area around the plaster cast. Grain size analysis is a tool best suited for description and possible exclusion, rarely can it be used as a diagnostic tool [6]. Further, when grain size analysis is undertaken on soil taken from a suspect's artefacts (shoes, clothing, vehicles etc.)…”

“…They also serve as important sentinels of past environmental changes across multiple temporal and spatial scales [1]. Sediment texture and its distribution are one of the most fundamental and pervasive method undertaken for the analysis of sediments and soils [2]. Grain size analysis describes the sediment size distribution and provides environmental information as mechanism of how the sediments are deposited in different sedimentary basins [3].…”
