Analytical procedures used in the Geochemical Laboratory of the Survey

This report describes the system of routine analysis of rocks and silicate minerals used in the chemical laboratories of Grønlands Geologiske Undersøgelse (GGU) in the last three years. The first part is a short summary of the principles behind the methods used with references to original sources in the literature. In the section on analytical accuracy a series of results are given some of which are treated statistically. These are meant as a guide to the accuracy of the methods used and as a basis for further, more developed statisticai studies. The last section of the report on procedures contains descriptions of the separate methods used in nummerical order and is used as a "recipe book" in the laboratory.
