Deniliquin multiple-ring feature, Circular geological formation near Deniliquin, Australia.
The Deniliquin multiple-ring feature is a geological formation buried beneath the surface in the Murray Sedimentary Basin, consisting of concentric rings created by an ancient meteorite impact. These rings extend outward in layers that can only be detected through specialized magnetic measurements of the ground.
The structure was discovered in the late 1990s by scientists studying magnetic field patterns in southeastern Australian landscapes. Analysis of these buried rings helped geologists better understand the effects of major impacts on continental structure.
The formation represents a significant research site for Australian geologists studying the effects of meteorite impacts on continental structures and landscape evolution.
The location lies about 30 kilometers northwest of Deniliquin and is not directly accessible since the structure is buried underground. Visitors can explore the surrounding landscape and learn about the formation through published research and geological maps.
The structure features a central magnetic zone about 120 kilometers across, much larger than many famous impact craters found elsewhere on Earth. This makes it potentially the largest known impact system on the planet.
