In the spring of 1968 we finished setting up and testing the K/Ar dating apparatus at Mineralogisk Museum. A small number of GGU samples were dated during the summer months. Since September a fair amount of time has been spent on testing the suitability of atomic absorbtion spectrophotometry for determining K, Rb and Sr. These efforts, however, have not yet been very successful although a considerable amount of experience has been gained. In November and December our main efforts were concentrated on the first attempts at using the solid source mass spectrometer (Atlas CR 4) at Fysisk Laboratorium II, H. C. Ørsted Institute, for isotope analysis on Rb and Sr.
