Dunes of Aspledon Undae on Mars

... that Martian dunes of Aspledon Undae (pictured) may have formed due to erosion of the Planum Boreum cavi unit? Source: " Next, renewed erosion of the Planum Boreum cavi unit (ABbc) yielded dunes of the Olympia Undae unit (ABou) in the vicinity of the cavi. Distal dune fields, including Siton, Aspledon, and much of Olympia Undae may have originated during earlier erosional episodes of the cavi unit and include former sources along the margins of Planum Boreum, such as Rupes Tenuis, that are now depleted."

The only issues I have is the QPQ and the missing citations for the last three sentences of the second paragraph. The article is rather short, but nonetheless, it does meet the length criteria. There's no POV violations, if that's even possible with an article like this. This page was created on August 29, so it's within the 7-day period.--12george1 (talk) 20:17, 3 September 2017 (UTC)

Hi 12george1. Thank you for your review. For the four densest dune fields in the northern circumpolar region of Mars, please see: File:Distribution of dune fields in the Planum Boreum region.PNG and the associated paper. For the five named dune fields on Mars, please see List_of_extraterrestrial_dune_fields#Mars. I know Wikipedia is not a reliable source, but it is a fact that there are no other dune fields on Mars named by the International Astronomical Union. As far as Aspledon Undae lying on Vastitas Borealis (the northern wastelands of Mars), please see this map and associated pdf. Another proof that Aspledon lies on Vastitas Borealis, is the cited fact that Siton Undae, to the north of Aspledon, also lies on Vastitas; please see Siton's article for the citation. I know, this may be not too strong for a reference, but it is also rather simple to discern. In any case, I added sources to these sentences. Meanwhile, please let me know if my explanations sound ok to you, otherwise I may have to remove these sentences, although, they are widely accepted, and easily verifiable. I also have done my QpQ now by reviewing Template:Did you know nominations/James Amster. Thank you. Dr. K. 04:56, 4 September 2017 (UTC)

Closing per 12george1's review, as the sentences are now cited and the QPQ complete. --Usernameunique (talk) 21:19, 4 September 2017 (UTC)
