A reconnaissance K/Ar dating programme on rocks from western Greenland has been carried out with an Ar-extraction apparatus set up at Fysisk Laboratorium II, H. C. Ørsted Institut. The mass spectrometric Ar determinations were carried out in the same labaratory by the second author. With the completion of this reconnaissance programme the extraction apparatus was moved to the Mineralogical-Geological Institute of the University of Copenhagen. Major changes are being made in connection with the re-establishment of the dating laboratory, and dating will not be resumed before the spring of 1968.
