An area of about 12,000 square miles was mapped in the field seasons 1950-51. It contains four Pre-Cambrian rock groups ranging from Archaeozoic to Uppermost Proterozoic. The main groups in the area, the Mt. Isa and Lawn Hill Groups, are shallow-water geosynclinal sediments involved in a Proterozoic orogeny which resulted in fairly intensive folding along dominantly north-south axes, together with much faulting. The geological features discussed in this report include physiography, topography, stratigraphy, igneous activity, structure, mineral deposits and water supply.

The principal alternative sites for an administrative centre which have been considered or suggested are discussed from the points of view with which a geologist and vulcanologist is primarily concerned - namely vulnerability to volcanic action, earthquakes, and tidal waves, foundations, water supply and accessibility of material suitable for road resurfacing, aggregate, etc. The areas considered are Rabaul, Nonga-Tavui, Keravat-Kabaira, Vunakanau-Taliligap, and Koko-Rapopo.
