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… 

Talundilly, Western Queensland, Australia: geophysical and petrological evidence for an 84 km-large impact structure and an Early Cretaceous impact cluster

The Talundilly Structure, southwestern Queensland, Australia, is represented on 2D seismic reflection transects as a major seismic anomaly disrupting the consistent ‘C’ seismic–stratigraphic horizon

The Diamantina River ring feature, Winton region, western Queensland

ABSTRACT The Diamantina ∼120 km-diameter ring feature, a unique feature in western Queensland, is manifested by a near-360° circular drainage pattern, radial creeks and a coincident radiometric

Australian Impact Structures >10 Km-Large

The geological antiquity of Australian land surfaces and the sedimentary and volcanic cover of Precambrian cratons in the central and western parts of the continent, allow preservation of a range of

Ring and Dome Features, Possible and Probable Impact Structures

Circular drainage patterns, round lakes and oval depressions may provide hints of possible underlying ring or dome structures, requiring field tests or drilling where no outcrop occurs (Grieve RAF,

An Impact Crater in Palm Valley, Central Australia?

We explore the origin of a ~280 m wide, heavily eroded circular depression in Palm Valley, Northern Territory, Australia using gravity, morphological, and mineralogical data collected from a field



Tookoonooka, a large buried early Cretaceous impact structure in the Eromanga Basin of southwestern Queensland, Australia

Th Thin sections from a centrally located exploration well reveal an impact melt breccia, composed of local Ordovician quartz-mica schist bedrock, which confirms an impact origin for Tookoonooka.

Woodleigh, Southern Carnarvon Basin, Western Australia: history of discovery, Late Devonian age, and geophysical and morphometric evidence for a 120 km-diameter impact structure

The discovery of the Woodleigh impact structure, first identified by R. P. Iasky, bears a number of parallels with that of the Chicxulub impact structure of K – T boundary age, underpinning

The Acraman asteroid impact, South Australia: magnitude and implications for the late Vendian environment

Acraman, located in the 1.59 Ga Gawler Range Volcanics on the Gawler Craton, South Australia, is a complex impact structure that is now eroded ≥2.5 km below the original crater floor. The geology,

Yallalie: a buried structure of possible impact origin in the Perth Basin, Western Australia

An enigmatic buried structure, located in Mesozoic sedimentary rocks in the Perth Basin, Western Australia, was discovered in 1990 by Ampol Exploration. The basin-like Yallalie structure (centred on

Origin of a late Eocene to pre‐Miocene buried crater and breccia lens at Fohn‐1, North Bonaparte Basin, Timor Sea: A probable extraterrestrial connection

Abstract— Seismic reflection data and an at least 350 m thick, PGE‐rich carbonate breccia lens intersected by the Fohn‐1 exploration well in the Timor Sea off northern Australia, are interpreted in

The Talundilly Anomaly and its Implications for Hydrocarbon Exploration of Eromanga Astroblemes

In the Talundilly area of the Eromanga Basin there is a circular area 95 km across with disturbed seismic character. This disturbance is most readily recognized by the absence of the strong 'C'

Structure and Evolution of the Volcanic Cauldrons, Ring Complexes and Associated Granites of the Georgetown Inlier, Queensland

THE Georgetown Inlier in North Queensland covers an area of about 37,000 square miles and lies on the western flank of the Palaeozoic Tasman Geosynclinal Zone (Fig. 1). It consists largely of

The geophysical signature of terrestrial impact craters

A major tool in the initial recognition and study of terrestrial impact craters, ∼20% of which are buried beneath postimpact sediments, is geophysics. The general geophysical character of terrestrial

Original size of the Vredefort Structure: Implications for the geological evolution of the Witwatersrand Basin

Abstract— Historically, there have been a range of diameter estimates for the large, deeply eroded Vredefort impact structure within the Witwatersrand Basin, South Africa. Here, we estimate the
