Talk:Bituminous coal

message: This article contains some very obscure words: e.g. antamen and orogenies.  We have no article on antamen, and I can't find the word at dictionary.com.  Spelling error?  Orogenies looks like a plural from oro (I think an orodryad is a mountain nymph so it probably means mountain) and genies looks like a plural of genesis meaning formation, so mountain-making, but is there a less technical word we could replace these with?

message: I'm finding it difficult to avoid a U.S.-centric discussion of the properties defining bituminous coal and its subranks. The ASTM definition and subranking is widely published, but I cannot dredge up a source for the ISO subrankings that is not behind a paywall and inaccessible to me; only an indirect reference to the vitrinite reflectance limits for bituminous coal as a group. --Kent G.

message: Currently, under Occurrence and production (4th paragraph), it reads: "Coal deposition was interrupted by the Permian-Triassic extinction event, but resumed later in the Permian." That puts the Permian period after the PTME, and that's a joke of course. The title of the reference added to that statement is "Global coal gap between Permian–Triassic extinctions and middle Triassic recovery of peat forming plants." Thus it seems that instead of 'Permian' it should have read 'later in the Triassic' here. I can only see the first page of the paper, so could someone who has access to the full paper check my suspicion and then change the text in our page accordingly? Thanks.  Wikiklaas  19:14, 30 October 2023 (UTC)

message: There is a severe deficit of references for claims made in the introductory paragraphs of this article.
Of particular note the claim that "It is the most abundant rank of coal" is not readily verifiable.
A short search indicated to me that it might (barely) be the largest contributor to confirmed reserves, but this is not actually what is claimed. 
Notably, historical usages of coal may have skewed the current distribution of reserves away from the ratios of natural abundance, and as the demand for lignite falls due to economic and political pressures, it is not economical to fully confirm reserves of coal that are not economical - which excludes them from being counted in many official statistics.
In general, the introduction needs citations, and some claims may be spurious. MasterOfGrey(MoG) (talk) 04:22, 16 February 2024 (UTC)
