Abstract

This report deals with a triangular area of pre-cambrian meta-sediments, totalling about six square miles in which occur copper-uranium orebodies of the Rum Jungle area. The area is situated 55 miles south-south-east of Darwin, Northern Territory. Plane table mapping of [a] portion of the area was carried out by N.J. Mackay and D.J. Gates in 1950 and the area mapped was extended by E.K. Carter in 1951 to cover the whole of the embayment area. The meta-sediments of the area form a large dragfold in the north side of the N 60°E striking Giant's Reef fault, along which there is a horizontal displacement of 3.25 miles. About 5,000 feet of varied meta-sediments are present. The carbonaceous slates are the host rocks for mineralization. Granite and granitized sediments lie to the north, east and south of the area and they occupy the core of a domal structure in the meta-sediments. Three periods or phases of faulting are recognised, the first is the post-granite Giant's Reef faulting, which produced the major dragfold, the copper-uranium mineralization may have been associated with this period of faulting. The second is an axial plane shearing of the dragfold, which is post-mineralization in age. The third system of faults consists of a large number of cross-faults which strike from N 60°W to N 30°E and which have displaced the granite margins, Giant's Reef fault and the axial plane shear. The known copper-uranium mineralization is confined to the axial region of the dragfold and is found almost entirely in carbonaceous slates. The most favourable area for further prospecting appears to be under the deep soil along the axial plane zone, east-north-east of Dyson's Prospect.
