Lack of needed sources[edit]

This articles is sorely in need of independent secondary, reliable sources by people outside of Geoscience Australia. So far the best that I can find are:

I. sources that discuss the Diamantina River ring feature in detail:

Glikson, A., 2018. Structure and origin of Australian ring and dome features with reference to the search for asteroid impact events. Tectonophysics, 722, pp.175-196.

Glikson, A., Korsch, R.J. and Milligan, P., 2016. The Diamantina River ring feature, Winton region, western Queensland. Australian Journal of Earth Sciences, 63(5), pp.653-663.

Glikson, A.Y. and Pirajno, F., 2018. Ring and Dome Features, Possible and Probable Impact Structures. In Asteroids Impacts, Crustal Evolution and Related Mineral Systems with Special Reference to Australia (pp. 123-156). Springer, Cham.

II. Outside sources that discuss the Diamantina River ring feature in detail:

Rahman, Z.U., 2021. Remote sensing analysis of unnamed crater in Eastern Australia. Natural and Applied Sciences International Journal (NASIJ), 2(1), pp.1-11.

III. Outside sources that briefly mention the Diamantina River ring feature in passing:

Donchak, P.J.T. , 2021. Notes on the geological interpretation of deep seismic transect 14GA-CF1, including inferences from other associated regional datasets. Queensland Geological Record 2021/04.

Kennett, B.L.N. and Liang, S., 2021. The transition from the Thomson Orogen to the North Australian Craton from seismic data. Australian Journal of Earth Sciences, 68(5), pp.628-640.

These sources neither provide any solid evidence of this feature being related to an extraterrestrial impact nor convincing case for this feature being notable. Paul H. (talk) 04:01, 20 December 2021 (UTC)[reply]

Notable example of ring feature.[edit]

Despite my previous reservations about the notability of the Diamantina River ring feature, I would regard it as being notable because there exists published physical evidence indicating that it represents a significant buried geologic structure of unknown origin. Also, it is an unusually well-defined example of a ring feature / ring structure because of the course of the Diamantina River. Normally, other ring features / ring structures are more ambiguous because the criteria used to define them are more subjective and speculative in nature and lack the geophysical ground truthing. Therefore, I would keep this article unlike the case of the more speculative and seemingly imaginary Middle-Urals Ring Structure. Paul H. (talk) 15:27, 20 December 2021 (UTC)[reply]

For a discussion of and maps showing speculative Australian ring features, go see:
