The Clarence Moreton Basin is a Mesozoic sedimentary basin on the easternmost part of the Australian continent. It is located in the far north east of the state of New South Wales around Lismore and Grafton and in the south east corner of Queensland. It is the part of the Great Artesian Basin that extends to the east coast in Australia's central eastern lowlands. Description It formed by oblique extension of the underlying Paleozoic New England Orogen basement. It consists of continental deposits, starting with a small amount of Triassic coal beds, and then mostly Jurassic and Cretaceous sedimentary rocks. The basin covers . The basin was named when the Clarence Basin (named after the Clarence River) and Moreton Basin in Queensland were proved to be one structure. Oil is likely to be present in the basin. Stratigraphy The oldest rocks in the Clarence Moreton Basin of New South Wales are the Chillingham Volcanics. These are from some time in the Triassic period, and crop out in a band north and south of Chillingham. They consist of conglomerate at the base, rhyolite, lithic rhyolitic tuff, and shale. The Nymboida Coal Measures extend from Nymboida to Kangaroo Creek. They consist of lithic sandstones (wackes, minor arenites), siltstone, polymictic conglomerate, coal, rhyolitic tuff, and basalt. The total thickness is over . The outcrop is , and it forms a north west trending band long on the southwest tip of the basin. Fossils reveal a date of middle Triassic. A lower part is called Cloughers Creek Formation. The Basin Creek Formation includes the coal mined at Nymboida. The Bardool Conglomerate forming a thick layer, is also a unit in the coal measures. The conglomerate includes a thick layer of basalt exposed at Copes Creek. The Neranleigh-Fernvale Beds are up to 3,500 metres thick. The Red Cliff Coal Measures date to the Late Triassic. It forms an outcropping belt wide and long from Buchanans Head through Red Cliff. The Evans Head Coal Measures are correlated with these, but are further up the north coast at Evans Head. The basin was next uplifted and eroded and then deepened considerably and Bundamba group rocks form a complete V shape on both sides of the basin. In the northern parts the rock is mostly friable sandstone, but in the south it is divided into conglomerate below and siltstone above. The Laytons Range Conglomerate rests on the basin
