Report is result of a rapid geological reconnaissance of the Federal Territory made primarily to locate deposits of limestone and shale, suitable for the manufacture of Portland cement, and other materials likely to be of value in the building of the Federal City.

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.
