Proposed sampling methods for the Madagascar regional geochemical mapping project

This report was prepared prior to the commencement of the Madagascar geochemical sampling in June 2005. In the absence of any orientation phase for the project, the suggested sampling methodology is based on the experience gained from previous international geochemical mapping projects, particularly Mauritania and Morocco. Detailed procedures for collecting stream sediment and panned concentrate samples are given along with information on how sites and samples should be numbered and sample field cards completed. The annexes to the report contain useful information that will be relevant and helpful to the project.
