  • This map is part of a series which comprises 50 maps which covers the whole of Australia at a scale of 1:1 000 000 (1cm on a map represents 10km on the ground). Each standard map covers an area of 6 degrees longitude by 4 degrees latitude or about 590 kilometres east to west and about 440 kilometres from north to south. These maps depict natural and constructed features including transport infrastructure (roads, railway airports), hydrography, contours, hypsometric and bathymetric layers, localities and some administrative boundaries, making this a useful general reference map.

  • The surface geology of Queensland ranges in age from Palaeoproterozoic to Recent. The oldest rocks largely occur in the Mount Isa and Georgetown Inliers in the northwest and central north of the state respectively. These rocks have undergone greenschist to amphibolite facies metamorphism and were extensively intruded by granite during the Mesoproterozoic. Metamorphics of Meso to Neoproterozoic age occur in the Coen Inlier in eastern Cape York, in the Hughenden-Charters Towers-Townsville region to the south and east of Georgetown, and also further south in the Anakie Inlier. During Cambrian to Ordovician times, extensive carbonate dominated, marine sedimentation took place in the Georgina Basin, West and southwest of Mount Isa. These rocks were subsequently faulted and gently folded prior to the Devonian, perhaps during the mid-Ordovician Thompson Orogeny. Silurian to Devonian marine sedimentation is preserved in the Hodgkinson and Broken River Basins in the north east of the state while similar aged, arc related deposits accumulated in the New England Orogen which occupies a 200 km wide coastal strip between Bowen and Brisbane in the southeast of the State. The Hodgkinson - Georgetown region and New England Orogen were extensively intruded by granite during Carboniferous to Permian times. Permian to Triassic sediments of the Galilee and Bowen Basins outcrop in the central east of the state while similar aged sediments accumulated to the east and southeast within the New England Orogen. Widespread sedimentation during the Jurassic to Cretaceous (Carpentaria, Eromanga, Mulgildie, Surat, and Laura Basins) blanketed large areas of older bedrock, particularly in the central, southern and south western parts of the state. Finally, Cainozoic cover units comprise approximately half the surface geology with sand plain (Czs), sand plain with dunes (Czd), colluvium (Qrc), alluvium (Qa), and Tertiary to Quaternary basalt flows comprising the major components. The data set was initially compiled from older regional data sets including those covering the Eromanga, Surat and Carpentaria-Karumba Basins. Extensive areas were recompiled using more recent 1:250 000 and 1:100 000 scale mapping, particularly in the Georgetown-Charters Towers-Ebagoola region, and also the area of the New England Orogen. The data set includes nearly 1800 named, informal or unnamed units.
