Mineralogical analysis of further stream sediments from Nigeria

This report presents the results of mineralogical characterisation of a further suite of sixty stream sediment samples from Nigeria. The samples were submitted for analysis by Dr Roger Key (BGS) and his team as part of the ‘Technical Assistance Services for the Geochemical Mapping of Nigeria’ project which aims to provide baseline geoscientific information for mineral exploration and environmental management through a study of the distribution of important metallic elements. Particular interest was expressed in determining the hosts for the elevated levels of Zr in the stream sediments. Full sample details, including Zr geochemical data from inductively coupled plasma-mass spectrometry (ICP-MS) are listed in XTable 1X. This study follows a smaller pilot study carried out on a suite of seven stream sediments samples from the same project (Kemp et al., 2009).
