The Shoemaker Impact Structure, Western Australia
Under Construction
The Shoemaker Impact Structure is located in central Western Australia and was formerly known as the Lake Teague Ring Structure Butler (1974). It is located at 120 deg 53 min east and 25 deg 52 min south on the Nabberu SG51-05 1:250 000 map sheet and the Nabberu 3046 1:100 000 map sheet. It comprises a central granitic core about 12 km across surrounded by a complex ring syncline about 20-25 km in diameter. The structure is located in rocks of the Palaeoproterozoic Earaheedy basin close to the northern exposed limit of the Archaean Yilgarn Craton. The information summarised here has been derived from Pirajno (2002), Pirajno et al (2003) and Bunting and Freeman (2012).
In 2012, the Meteoritical Society hosted a field excursion to some of the WA craters and impact sites, and the extract for the Shoemaker visit can be found here.
