Abstract
This report is supplementary to a report on the Kuridala Copper Field, Cloncurry district, Queensland, by C.J. Sullivan and R.S. Matheson (1950) and should be read in conjunction with that report. Sullivan and Matheson showed that, in the known deposits, ore occurs in the Hampden Fault, where slates in the hanging-wall of the fault are thrust against the resistant amphibolites occurring in the footwall (western side) of the fault. The rocks to the west of the fault were known, from mapping carried out by Broadhurst (1936), to be folded into a synclinal structure and it was postulated by Sullivan and Matheson that further ore may be found where the fault intersected amphibolites occurring stratigraphically below the amphibolites near which the known ore occurs (Sullivan, and Matheson 1950, Plate 1, Regional Cross Section). It was realised by Sullivan and Matheson that the prediction of a position of the amphibolites, at depth, involved considerable uncertainty and it was thought that further mapping of the Western Syncline might enable a reasonably accurate interpretation of the position of the amphibolites to be made. The [present] field work was carried out between 20th August and 18th September, 1951, by K.W.B. Iten and R.A. Searl of the Bureau of Mineral Resources and J.H. Brooks of the Geological Survey of Queensland. The general postulations by previous investigators concerning the relationship of geological structure to ore occurrence were checked but no detailed investigation was made of the size, shape and grade of known ore-bodies; the present investigators consider that the interpretation by Sullivan and Matheson (1950) of the structural controls of ore deposition may be correct.
