Sampling was carried out at 149 different sites along and across the Peninsular Ranges. The samples rock types range in

composition from few gabbros and diorites, to mainly tonalites and some granodiorites. Overall, the rocks are very fresh and

unfoliated preserving primary textures.

Appendix-3Sample localities for recalculated K/Ar dates, after Krummenacher and others, 1975 and Steiger

and Jagger, 1977.
