The mandate of Commissions of the International Union of Geological Sciences (IUGS) is to set standards in their own discipline. Therefore, the obligation of the Commission on Global Geochemical Baselines (CGGB) is to provide the standards for establishing the Global Geochemical Reference Network.
The Global Geochemical Reference Network, according to Darnley et al. (1995), is based on the collection, preparation and analysis of a variety of sample media with standardised methods from random catchment basins within 160x160 km grid cells covering the entire land surface of the Earth, known as the Global Terrestrial Network (GTN).
The recently published Manual of Standard Methods presents, for the first time, a comprehensive overview of the standardised geochemical methods that should be employed across the land surface of the Earth to map the distribution of chemical elements in various media. Applying these methods will produce internally consistent quality-controlled data sets for each sampling medium for multipurpose use. The Manual provides extensive information on sampling protocols for rocks, residual soil, humus, stream water, stream sediments, overbank and floodplain sediments. There are also chapters discussing sample site selection; sample preparation; quality control procedures, including the development of project reference materials; analytical methods; data management; map preparation; project management; and information on how to level existing geochemical data sets. Any applied geochemist carrying out a geochemical mapping project at any scale should find a wealth of useful information within the pages of this Manual.
As this Manual is important to applied geochemists all over the world, for each Chapter the original Microsoft Word files, all the original figures, and Microsoft PowerPoint files are provided in a zip file.
The Microsoft PowerPoint file of each Chapter includes all the figures used, and in some cases some text was transferred. The PowePoint files can be used for teaching purposes.
