Laurel formation in D.C.
[edit]@Abyssal: You seem the main editor on this article.
I keep coming to this article when looking up the Laurel Formation (Cambrian) that is in the Washington D.C. area on the Piedmont terrain.[1][2]

I'm fairly confident it is not the same formation since this article is about a formation from the Silurian period. It seems both Laurel Formation could use separate articles. Do you agree?
I am not at all familiar with the hierarchies used here to add formations, so that the various layers above and below are made clear, the extent, etc., so I would rather not do that without help. Also, I would imagine there are excellent databases that document nearly all the geologic formations throughout the U.S. (and world), but I am not seeing that as a reference in this article, except as relates to fossils. --David Tornheim (talk) 08:08, 26 December 2018 (UTC)
- @David Tornheim:I agree that these are distinct units that could use separate articles, so I moved this one to Laurel Formation (Silurian). Laurel Formation (Cambrian) is free to be created. Overlying and underlying stratigraphic units can be noted in both the text of the article and its infobox. When you're editing the article, the code for the infobox contains entries like "| underlies =" and "| overlies =" and you can just input the information following the equal sign. As far as the database situation go, as far as I can tell, things aren't as rosey as you'd expect. The best database for North American units is the US geological survey, but it doesn't actually note which units overlie eachother. I end up relying on stratigraphic charts or papers for that.
