A method developed for radiochemical determination of gold in rock samples has been applied to six Bulgarian, four ZGI (GDR) and one USGS geostandards. The method is based on acid dissolution of the sample, followed by extraction of gold with copper diethyldithiocarbamate solution in CHCl 3 . The chemical yield was determined by using 199 Au tracer. The present data are compared with published values for the ZGI and USGS samples.
