Stream sediment geochemical mapping of Sierra Leone : orientation survey and roadmap to commencement

This report on Stream Sediment Geochemical Mapping of Sierra Leone: orientation survey and roadmap to commencement, has been developed by technical experts from the British Geological Survey (BGS) and the Directorate of Geological Survey (DGS) at the National Minerals Agency (NMA). It is the outcome of an orientation survey undertaken by geologists of both BGS and DGS, specifically to guide and inform the planning of the proposed nationwide geochemical mapping of Sierra Leone. The primary objective of this report was to form the basis for the development of protocols and procedures for the three main stages of the proposed nationwide geochemical mapping campaign: sample collection, sample preparation and sample analysis.
