AbstractThe establishment of a chemical laboratory for the analyses of geological materials (rocks and groundwaters) at the Geophysics Institute (UNAM, Mexico) is described. The objective was to establish a laboratory capable of obtaining good quality analyses with minimum expense. The results had to be adequate to use in the study of rock geochemistry, hydrogeochemistry, and quality of groundwaters. The project is being developed in two stages. The first is to design methods for the quantification of major element oxides in rocks and physicochemical parameters in waters. For that purpose, wet methods were developed. The second stage in the development of the laboratory has consisted of the establishment of a technique for the quantification of metallic contaminants in waters and trace elements in rocks. These analyses are in development using an atomic absorption spectrophotometer and a polarograph recently acquired by the laboratory.
