GA review (see here for what the criteria are, and here for what they are not)
It is reasonably well written. a (prose, spelling, and grammar): b (MoS for lead, layout, word choice, fiction, and lists): It is factually accurate and verifiable. a (references): b (citations to reliable sources): c (OR): d (copyvio and plagiarism): It is broad in its coverage. a (major aspects): b (focused): It follows the neutral point of view policy. Fair representation without bias: It is stable. No edit wars, etc.: It is illustrated by images, where possible and appropriate. a (images are tagged and non-free images have fair use rationales): b (appropriate use with suitable captions):
Overall: Pass/Fail:

Looking good, just some tweaks. Ping me when done. Sammi Brie (she/her • t • c) 23:18, 14 March 2024 (UTC)[reply]

Did you know? If you fancy doing so, I always have plenty of GA nominees to review. Just look for the all-uppercase titles in the Television section. Reviews always appreciated.

• There are two MOS:SEAOFBLUE consecutive separate links in the lead, but they are technical terms that go together and need that high link density, so I am not opposed.
• Walvis-Tristan da Cunha Probably should have an emdash (–) in hyphenation involving a term with spaces.

  I confess that I don't know if that is necessary. Jo-Jo Eumerus (talk) 08:48, 15 March 2024 (UTC)[reply]

• There is a region on the Mid-Atlantic Ridge southwest of the seamounts where there are fewer earthquakes than elsewhere along the ridge, the central valley of the ridge is absent and where dredged rocks share geochemical traits with the Discovery Seamount. The sentence structure, despite its absence elsewhere, would benefit from a serial comma after "absent"

  OK. Jo-Jo Eumerus (talk) 08:48, 15 March 2024 (UTC)[reply]

• Petrological anomalies at spreading ridges have been often attributed to the presence of mantle plumes close to the ridge and such has been proposed for the Discovery hotspot as well. A comma is needed after "ridge" for a different reason: WP:CINS

• tephriphonolite trachyandesite Are these two list items or one? If they are two, a comma is missing.

  Added. Jo-Jo Eumerus (talk) 08:48, 15 March 2024 (UTC)[reply]

• Is there a link for "emplaced"?

  No, I thought that was a common word. Jo-Jo Eumerus (talk) 08:48, 15 March 2024 (UTC)[reply]

• The latter large igneous province may have formed at a triple junction around the nascent South Atlantic Ocean, and together with hotspots farther north precipitated the rifting of the South Atlantic. Reorganize the commas as such (bolding highlights change area): The latter large igneous province may have formed at a triple junction around the nascent South Atlantic Ocean and, together with hotspots farther north, precipitated the rifting of the South Atlantic.

  Done. Jo-Jo Eumerus (talk) 08:48, 15 March 2024 (UTC)[reply]

• 11: Schwindrofska et al. 2016, p. 169. Multi-beam echo-sounding mapping of the Discovery Rise shows that all of the 11 seamounts mapped are volcanic guyots ... Using the classification diagram of Nb/Y versus Zr/Ti (Appendix C, Fig. C.1), the rock types comprise basalts, alkali basalts, tephriphonolites and phonolites. ... The more mafic and intermediate lavas contain olivine, clinopyroxene, plagioclase, spinel and Fe–Ti oxide phases Y
• 29: Zhou et al., p. 430. The Tristan-Gough, Discovery and Shona EM1 volcanic tracks are derived from a common low-velocity anomaly (superplume-like structure with three branching arms) ascending from the outer margin, possibly lower primoridal layer, of the African large low-shear-velocity province (LLSVP). Y
• 30: Kingsbury et al. 2023, p. 482. When observed together, the 135 Ma EQUAMP with a potential St. Helena plume source, the 135 Ma Paraná-Etendeka LIP with a likely Tristan plume source, and the 135 Ma magmatic province, we herein propose to call the GCF-LIP, which potentially arose from the Discovery plume, appear to have originated from a ~3 300 km long mantle plume “curtain” at the edge of the Africa Large Low Seismic Velocity Province ... it is possible to consider that the 140 to 120 Ma kimberlite fields of South Africa, which Ernst and Jowitt (2013) mention as a potential magmatic product of the Paraná-Etendeka LIP, may in fact be genetically related to the GCF-LIP rather than the Paraná-Etendeka plume centre ... The Discovery plume appears to have occupied a region either proximal to or at the centre of a triple-junction Y
• 33: Gibson and Richards 2018. For the Wolf–Darwin Lineament at Galápagos, the Discovery Ridge linking the Discovery plume to the nearby southern Mid-Atlantic Ridge, and the Rodrigues Ridge linking the Réunion hotspot to the Central Indian Ridge, the associated excess crustal volumes can be estimated from the products of their approximate lengths... Y
• 38: These two density anomalies seem to be connected. We postulate that during the initial stage of plate motion the Discovery hotspot was located close to the ridge and could therefore affect the SMAR through the migration of plume materials. The relative movement between the African and the American plates however gradually drove the Discovery hotspot away from the ridge which limited the migration of the plume materials beneath the ridge. Also mentions the neodymium (Nd) component. Y
• 41: The geochemical similarity found for the enriched component in basalts of the Walvis-Rio Grande ridges and Discovery seamount can, in our opinion, be more logically explained by interaction between the rift zone and Tristan hotspot, which formed the Walvis Ridge at magma melting. Y
• 49: Abundant bamboo corals (Keratoisis sp.) were only observed on Discovery seamount, where high abundance of sea urchins and naked colonies were also observed. Y

No issues. Earwig is flagging mostly work titles and some banal phrases like "beneath the South Atlantic Ocean".
