The Yilgarn Craton is a large geological formation located in Western Australia. It is one of the oldest continental crusts on Earth, dating back over 3 billion years. The craton is primarily composed of granite and greenstone rocks, which are significant for understanding the early history of the Earth's crust. This region is rich in mineral resources, including gold, nickel, and iron ore, making it an important area for mining activities. The Yilgarn Craton also plays a crucial role in the study of geology and tectonics, providing insights into the processes that shaped the Australian continent and its natural resources.
