Gnargoo: a possible 75 km-diameter post-Early Permian - pre-Cretaceous buried impact structure, Carnarvon Basin, Western Australia

Iasky, R; Glikson, Andrew


The Gnargoo structure is located on the Gascoyne Platform, Southern Carnarvon Basin, Western Australia, and is buried beneath about 500 m of Cretaceous and younger strata. The structure is interpreted as being of possible impact origin from major geophysical and morphometric signatures, characteristic of impact deformation, and its remarkable similarities with the proven Woodleigh impact structure, about 275 km to the south on the Gascoyne Platform. These similarities include: a circular...[Show more]
