X-ray diffraction analysis of soil samples from abandoned mine sites in Cornwall (part 2)

This report presents the results of qualitative X-ray diffraction analysis (XRD) analysis conducted for the project ‘Fate and Transport of Heavy Metals’. The object of this project is to examine the environmental transport and fate of heavy metals, particularly in relation to abandoned mining and mineral processing operations. A set of soil samples separated into various size fractions, and into light and heavy fractions, was received from the BGS sample preparation facility and the details are listed in Table 1. These samples have previously be the subject of a whole-rock XRD study (McKervey, 2002).
