What is Acraman crater?
[[File:Acraman crater australia.jpg|thumb|250px|The crater is the circular area]] '''Acraman crater''' is a deeply eroded [[impact crater]] in the [[Gawler Ranges]] of [[South Australia]]. It is marked by Lake Acraman, a circular ephemeral [[playa lake|dry lake]] about {{convert|20|km|mi}} in diameter. The crater and the later discovery of its [[ejecta blanket|ejecta]] were reported in the journal ''[[Science (journal)|Science]]'' in 1986.<ref name=Williams1986>{{cite journal | author = Williams, G.E. | date = 1986 | title = The Acraman impact structure: source of ejecta in late Precambrian shales, South Australia | journal = Science | volume = 233 | issue = 4760 | pages = 200–3 | doi = 10.1126/science.233.4760.200 | pmid = 17737291 |bibcode = 1986Sci...233..200W | s2cid = 30059305 }}</ref><ref name=Gostin1986>{{cite journal | author = Gostin, V.A. |author2= Haines, P.W.|author3= Jenkins, R.J.F.|author4= Compston, W.|author5= Williams, I.S. | date = 1986 | title = Impact Ejecta Horizon Within Late Precambrian Shales, Adelaide Geosyncline, South Australia | journal = Science | volume = 233 | issue = 4760 | pages = 198–200 | doi = 10.1126/science.233.4760.198 | pmid = 17737290 | bibcode=1986Sci...233..198G|s2cid= 11307364}}</ref> The evidence for impact includes the presence of [[shatter cone]]s and [[shocked quartz]] in shattered [[bedrock]] on islands in Lake Acraman. == References == {{reflist}} [[Category:Impact craters]] [[Category:Geography of South Australia]]
