Liverpool is a meteorite impact crater situated in Arnhem Land within the Northern Territory. It was named after the nearby Liverpool River. The site is remote and difficult to access. The crater has a raised near circular rim averaging about 1.6 km in diameter. It was first noticed by geologists during reconnaissance geological mapping in the 1960s. The crater lies within flat-lying Paleoproterozoic sandstone of the McArthur Basin. This sandstone has been fractured and brecciated by the impact event to form the rim. Flat-lying and non-deformed sandstone that must have been deposited after the impact event is exposed within the center of the crater. Because the crater is quite well preserved, it can be argued that it was buried by younger sedimentary rock soon after the impact event; this younger rock has now been mostly eroded away except in the crater center. The crater filling sandstone was originally thought to be of Cretaceous age, leading to the Cretaceous age listed for the crater in older literature sources. However, more recent studies suggest that the infilling rock is more likely to be of Neoproterozoic age (1000-543 Ma) and therefore the crater is more likely to have formed at some time during the Neoproterozoic. No meteorite fragments have been found at the site. This is not surprising considering its great age; such fragments would have weathered away. Evidence supporting an impact origin includes the geological structure of the crater, and the discovery of shocked quartz. The crater is not perfectly circular, but is about 6% broader in a northeast-southwest direction and the internal parts of the crater are also asymmetric is such a way as to imply that the impact was oblique from the southwest
