The method of vacuum-thermic extraction (VTE) of Pb, Zn, Cd, Bi, Tl, As and Sb from soils with subsequent AAS determination of the elements as described previously [1] was adapted to the analysis of rocks. The design of the quartz extractor was improved and appropriate working conditions for a precise and accurate determination were developed. The method was applied to the analysis of various rock types.
