Deniliquin Multiple-ring Feature
The Deniliquin multiple-ring feature is a distinct deeply buried structure in southeast Australia. It is named after the town of Deniliquin. Its characteristics suggest that it is associated with an asteroid impact structure of diameter , which would make it the largest one on Earth, exceeding the largest verified one, the Vredefort impact structure of about in diameter. Description It is located beneath the Murray Basin, Murray Sedimentary Basin and partly beneath the Darling Sedimentary Basin, and centered about northwest of Deniliquin. The principal features of the Deniliquin structure are a multiple ring total magnetic intensity (TMI) pattern with the minimal TMI ring radius of ; a central quiet magnetic zone; circular Bouguer gravity patterns; an underlying Earth mantle, mantle Mohorovičić discontinuity, Moho rise about shallower than under the adjacent Tasman Orogen, Tasman orogenic zone; and radial faults associated with magnetic and demagnetized anomalies.

The town services a productive agricultural district with prominent dairy, rice, wool and timber industries. At the , the urban population of Deniliquin was . Prehistory Deniliquin is the namesake of the deeply buried Deniliquin multiple-ring structure, which is suggested to be at the core of a 320 mile diameter impact structure formed by a meteor strike over 400 million years ago, possibly responsible for the Late Ordovician mass extinction.
