Recent expansion
[edit]@Esculenta: I am struggling to find support for much of the content recently added to the article. Some if it is supported by Schofield et al. (2020), but many of the details are not, such as:
1 "Today the Carmel Head Thrust can be examined in coastal cliffs and foreshore platforms where the juxtaposition of dark, chlorite-bearing Cemlyn Bay mudstones against paler, lightly cleaved Llyn Alaw siltstones is obvious." As far as I can tell the thrust nowhere juxtaposes Cemlyn Bay formation strata against the Llyn Alaw Group, except possibly in the eastern part, but not on the coast even then. The paper also does not mention "siltstone" as a lithology developed in the group.
2. "... creating a narrow band of intensely sheared melange along the thrust surface." Schofield et al do not mention melange along the thrust zone.
3. "... the fault was reactivated as part of a broader Acadian compressional phase, but only minor additional slip is recorded." Schofield et al. refer to cleavage developed in mudstones of the ORS supporting a possible reactivation of thrust tectonics and mention renewed south-directed thrusting equated to the Acadian, but no quantification of any displacement.
4. "... Floian-to-Silurian mudstones of the Llyn Alaw basin..." Schofield et al state that the Llyn Alaw Group is Early-Middle Ordovician (Floian to Dariwillian).
This article is the first of 21 of your recent expansions that are on my watchlist that I've had time to check. The Schofield et al. (2020) paper is a useful addition, but a significant amount of rewriting is needed, which I will get round to. My only question is, where did the rest of the content come from? I'm hoping that the other 20 do not require so much post expansion work. Mikenorton (talk) 14:45, 5 May 2025 (UTC)
- Happy to revise based on your expert analysis (I'm very much an amateur); let me know if you see any further issues. Esculenta (talk) 15:34, 5 May 2025 (UTC)
