Marbles in the area mapped are equated with the Lower Cambrian Archaeocyatha limestones found elsewhere in the State. The Cambrian sediments which include arkoses, greywackes, and amphibolites are folded into a broad syncline in Section 113, with drag fold structures developed on the limbs. North of the main syncline numerous fold structures are developed on the eastern limb of the main fold, all these structures are interpreted as drag folds. In section 341 the beds swing westerly and dip steeply to the south. Total reserves of marble in the areas outlined are estimated at 88600 tons per vertical foot. It is possible that the marbles may be slightly more extensive than outlined on the accompanying map. Drilling is desirable to test the marble in depth and a tentative programme is laid out totalling 910 feet of drilling. Trenching to test the quality of marble outcrop is outlined on map 1960-0137L accompanying this report.
