This Bulletin presents the results of five months fieldwork carried out by a joint geological party from the Bureau of Mineral Resources and the Geological Survey of Queensland in 1958, and incorporates subsequent scattered field observations in more recent years. The area investigated is covered by the three One-Mile Sheets of Chillagoe, Mungana, and Almaden, and forms the north-western part of the Atherton 1:250,000 Sheet area, North Queensland. Metamorphosed and migmatized Precambrian schist, gneiss, and muscovite granite in the west are separated from folded Palaeozoic geosynclinal sediments by a large fault. The geosynclinal deposits are represented by Upper Silurian to Lower Devonian formations with mixed shelf facies, and, farther east, by the eugeosynclinal flysch sediments of the Middle to Upper Devonian Hodgkinson Formation. Remnants of unconformable lacustrine or estuarine sediments, probably Carboniferous, are also exposed. Upper Permian granites intruded these formations after they had been folded during a Carboniferous orogeny and subsequently eroded, and acid to intermediate volcanics, comagmatic and coeval with the granites, were extruded on a surface of low relief, commonly in ring complexes and cauldron subsidence areas. Associated with the granites is a widespread and varied mineralization which has given rise to numerous deposits of copper, lead, zinc, silver, gold, tungsten, molybdenum, bismuth, tin, fluorspar, and iron. The region remained stable and near sea-level until the Lower Cretaceous transgression from the west, during which sandstone and conglomerate were deposited under littoral conditions. Post-Cretaceous epeirogenesis combined with subsequent stages of faulting and erosion to sculpture the present-day landscape. The area has had an intermittent mining history which reached its zenith in the first ten years of the century, with a partial resurgence in the twenties, and a few subsequent short-lived spasms of activity.
