Forensic Soil Science and Geology
CONTAINS OPEN ACCESS
Forensic soil science and geology provides information and operational support to assist the police and law enforcement with criminal and environmental investigations. These include: crime scene examination and the collection of soil and other materials; analysis and interpretation of this geological trace evidence; and searches associated with homicide graves, counter-terrorism and serious and organized crime. This volume provides new and sophisticated field and laboratory methods and operational casework.

In a 2007 homicide in Western Australia, small (<0.5 mm diameter) red brick fragments and soil were identified on the victim's clothing (mainly bra), body (mainly hair) and vehicle. A comparative study of the mineralogy and morphology of the red brick fragments with red bricks from the paved area in front of the victim's house was undertaken by traditional laboratory X-ray diffraction (XRD) using low background Si wafer holders and a 0.5 mm focusing monocapillary attachment. Whilst significant similarities were observed between the two datasets, peak overlaps and poor resolution prevented a specific provenance to be determined. Additional analyses...
