Forensic Geoscience: Principles, Techniques and Applications
Forensic geoscience is an increasingly important sub-discipline within geoscience and forensic science. Although minerals, soils, dusts and rock fragments have been used as only begun to be recognized in the last ten years or so. The police and other investigative bodies are keen to encourage such developments in the fight against crime, particularly since many criminals show a high level of forensic awareness with regard to evidence such as fingerprints, blood and other body fluids. The papers in this volume illustrate some of the main principles, techniques and applications in current forensic geoscience, covering research and casework in the UK and internationally. The techniques described range from macro-scale field geophysical investigations to micro-scale laboratory studies of the chemical and textural properties of individual particles. In addition to forensic applications, many of these techniques have broad utility in geological, geomorphological, soil science and archaeological research.
Geophysics and burials: field experience and software development

Abstract
In the UK, geophysical survey methods have been increasingly applied in the search for clandestine burials and in the elimination of land from murder enquiries as part of a broader spectrum of systematic search techniques. This paper considers recent forensic search work and stresses the general resources and intelligence needed for a successful search, and the role played by geophysics. The main emphasis, however, is to discuss the applicability of ground-penetrating radar (GPR) in grave detection and to review recent developments in software, particularly the importance of high-resolution mapping. The paper also discusses the use of image analysis of both planes through blocks of buried landscape, together with predictive modelling and the value of 3-D analysis for data manipulation.
