Abstract Results are presented from K-Ar age measurements on Shap and Dartmoor granites, using both total volume and isotopic dilution techniques. Results were consistent to about 1%. Mean values are 265 plus or minus 5 million yr for the Dartmoor granites and 397 + 8 million yr for the Shap. Results of these measurements are compared with earlier results.
