Shoemaker crater
The Shoemaker crater in Western Australia (formerly known as Teague Ring) is an obvious impact crater, the remains of an ancient meteorite strike. Later research gave clear evidence for this, including the presence of shatter cones and shocked quartz.[1]
It is in dry central Western Australia, about 100 km (62 mi) north-northeast of Wiluna.[2] It is named after planetary geologist Eugene Shoemaker.[3]
It was dated to 1630 million years ago.[4][5] More recent dating by K–Ar methods give ages as young as 568 ± 20 mya.[6] This age could date the impact event or represent tectonic activity.
