The Adelaide Basin is a geological formation located in South Australia, primarily beneath the city of Adelaide. It is known for its sedimentary rock layers, which were formed over millions of years. The basin is significant for its natural resources, including groundwater and minerals, and plays a crucial role in the region's geology and hydrology. This basin is also important for understanding the area's geological history, as it contains fossils and evidence of ancient environments. The Adelaide Basin is a key area for scientific research and exploration, contributing to our knowledge of the Earth's processes and the development of the Australian continent.
