Ruach Planitia

(

)

... that that a large basin on Neptune's moon Triton may once have filled with liquid water cryolava, similar to how liquid silicates fill lava lakes on Earth? Source: Gregg, Tracy K. P. and collaborators "Planetary Volcanism across the Solar System" chapter 5 - Cryovolcanism (https://www.sciencedirect.com/book/9780128139875/planetary-volcanism-across-the-solar-system) Source says: Some features [on Triton] resemble volcanic calderas on Earth that are filled with fluid lava. Fig. 23E shows one such example, Ruach Planitia ... The plains contain clusters of pits, which may be volcanic vents from which the smooth material erupted, before ponding and filling the area enclosed by the scarps. (p. 219)
- Reviewed:
- Comment: Unsure about the wording of "liquid silicates", "liquid rock" or an alternative may be more appropriate. Leaving up to the reviewer to decide.

Article was created three days before nomination. Article meets adequate length & general guideline requirements, although the first sentence in Ruach Planitia#Discovery and naming doesn't seem to have a proper citation. Could that be fixed? WP:AGF on sources I cannot access, otherwise it looks good. No copyvio found w/ Earwig. Hook is interesting enough, AGF again as I cannot see the figure for a book I do not have access to. I recommend wikilinking silicate. No QPQ required. Good job on the article! Just let me know if you could get that citation issue sorted with. Thanks, B3251 (talk) 16:17, 2 May 2024 (UTC)

Added a reference to the NASA site for Voyager 2[1] as per these sections of text: Voyager photographed two-thirds of Neptune’s largest moon Triton ... Spectacular images of its southern hemisphere showed a strange, pitted cantaloupe-type terrain. and Voyager 2 was the first human-made object to fly by Neptune.. A similar reference has been added to its sister article, Tuonela Planitia. ArkHyena (talk) 07:53, 5 May 2024 (UTC)

@ArkHyena and B3251: it may be my unfamiliarity with the subject, by I can't find where the hook is mentioned/cited in the article. Can you help? ~~ AirshipJungleman29 (talk) 17:32, 11 May 2024 (UTC)

Here's the passage where the reference is cited: The flat floor of Ruach Planitia suggests that fluid cryolava infilled the depression, with the pits around Dilolo Patera acting as central vents whence material erupted from.[2]: 870 [9]: 219 . "Cryolava" in general implies a water-dominated erupted fluid, similar to how "regular" lava is usually silicate-dominated. This probably could be stated more explicitly in the article, to be quite honest. ArkHyena (talk) 19:43, 11 May 2024 (UTC)

ArkHyena yes, please try to state it more explicitly, otherwise the hook is likely to get pulled up at WT:DYK or WP:ERRORS. ~~ AirshipJungleman29 (talk) 21:14, 12 May 2024 (UTC)

Alright, clarified as: ... high-viscosity or high-volatility cryolava, a term for water-dominated material analagous to silicate lava. from source 9, page 162: There are good reasons to believe that water is the dominant component of cryomagmas on most icy bodies. Although there is much insight to be gained by using our understanding of silicate volcanic processes... ArkHyena (talk) 21:51, 12 May 2024 (UTC)
