Summary

The radioelement concentrations of K, U, and Th have been determined for 9 samples of granite from the Western Red Hills, Isle of Skye, Scotland, and for 10 granite specimens from the Mourne Mountains, Ireland, and are compared to 2 published results for Lundy Island granite. The concentrations are distinctly different for each of the 3 centres, and although the data do not provide conclusive proof, they favour generation of the granites by fractional crystallization of basic magmas.
