Abstract

This Bulletin presents the results of a regional and detailed geological survey of the Tennant Creek Gold-field. The main object of the investigation was to determine the structural controls of ore deposition. Systematic mining began on the Tennant Creek Gold-field in 1932. One hundred and thirteen mines were in operation before 1941. In 1951 only four mines, Noble's Nob, Eldorado, Peko, and Northern Star, were producing gold ore. To the end of June, 1950, 166,400 tons of ore of average grade 18.1 dwt. per ton were won. The sedimentary rocks of the region consist of folded and brecciated sediments which arc thought to range from the upper part of the Lower Proterozoic (Warramunga Group) to the lower part of the Upper Proterozoic (Ashburton Sandstone). The Warramunga Group consists of sandstones, siltstones, mudstones, and shales which grade into the overlying quartzite sandstone and conglomerate of the Ashburton Sandstone. The Warramunga Group are unconformably overlain by the Rising Sun Conglomerates, which are possibly Upper Proterozoic in age. These rock units have been intruded by adamellite and related porphyries. In one place a magnetite amphibolite dyke was noted.
