AbstractOne hundred and sixty-three new potassium-argon age determinations carried out on Canadian rocks and minerals are reported . Each age d e t er mination is accompanied by a description of the rock and mineral concentrate used; brief interpretive comments regarding the geological significance of each age are also provided . The experimental procedures employed are described in brief outline and the constants used in the calculation of ages are listed. Two geological time - scales are reproduced in tabular form for ready reference and an index of all published GSC K-Ar age determinations by primary NTS quadrangle has been prepared.
