Reports on the Geology of the Federal Capital Site

In 1911 a geological survey of the Canberra Federal City site was completed with a map. The rocks composing the site are somewhat contorted and folded sedimentary series of sandstones and quartzites, shales, slates, limestones, and volcanic tuffs, and this has subsequently been intruded by an igneous series, consisting principally of quartz-phorphyries and quartz-felsites.
