Hi a few pieces of advice:
 * citations go after punctuation. So your content should be Sentence.[citation][space]Next sentence.
 * I see that you bolded the term "Proto-Antilles". Wikipedia style guidelines are such that bolding is used in few circumstances. You wouldn't bold it unless typing in the phrase "Proto-Antilles" redirects you to that page (which it doesn't), so you can just remove the bolding.

Other than that, nice work! I appreciate all the citations 👍. Let me know if you have questions moving forward. Elysia (Wiki Ed) (talk) 20:34, 11 February 2019 (UTC)

Hey Lindsaeaceae here are some suggestions/potential edits from me that are long overdue... sorry about that!

Geology section: 1) First sentence is a bit wordy and confusing. I would suggest editing the sentence that includes "7,000 islands and islets..." and end this sentence after "...islets." Then I would suggest continuing in a new sentence with, "These islands and islets span over 3,000km (from the Florida peninsula down to the northern coast of Venezuela." or something like this? Just because the sentence as is, is a bit confusing. 2) Prior to saying "each of the three archipelagos of the West Indies...", I would suggest saying in an additional sentence that the West Indies is comprised of three archipelagos, the Greater Antilles, the Lesser Antilles, and the Lucayan Archipelago. Just because I don't think that it is self-explanatory that the West Indies = 3 archipelagos.

Greater Antilles section: 1) "The islands of the Greater Antilles are composed of strata of different geological ages including, the Precambrian, the Jurassic, and the Cretaceous." My suggested re-worded sentence structure followed by an additional sentence(s) that include a little more detail into what kinds of things have been found in the strata from each of the three different geological ages you mentioned already. Also big suggestion that will make things easier for people with no understanding or background knowledge of geology, including the dates for these periods after naming the period at least once. 2) I would re-word the sentence regarding the exposure of parts of the Greater Antilles above the water... It is a little confusing by what you mean by exposed. Sequentially there is no context until you get to the latter half of the sentence which provides clarity into what kind of exposure you are referring too.

General article: 1) Great information in your article. I am very happy I am peer-reviewing your article because I am getting a much-needed crash course into the Geology of the West Indies!! 2) I would suggest including the ages whenever you mention a geological period but that is just my suggestion, at the minimum I think it would be great if you define the geological period at least once after mentioning the name of the period. 3) Define Ma or just spell out million years ago... I don't think you defined it, but I am not sure it is common short-hand. 4) Maybe include a timeline of the geological periods, it will help people with little to no background follow what time periods you are referring to throughout your article. 5) Define jargony lingo like subduction, I don't think there is a hyperlink to a page that defines this.

I hope my suggestions weren't too much but overall I really enjoy following the changes you make to this article!

'''[A general question, I'm not sure how this page will link to the main pages that already exist about the Antilles, just keep in mind that you'll probably have to modify one of those just a little so that there is a link or links to this page. This looks great!!]'''

Geology
The West Indies is a geologically complex island system consisting of 7,000 islands and islets. The West Indies stretches over 3,000 km from the Atlantic Ocean near the Florida peninsula of North America south-southeast across the Caribbean Sea to the northern coast of Venezuela. These islands include active volcanoes, low-lying atolls, raised limestone islands, and large fragments of continental crust containing tall mountains and insular rivers. Geologically, the West Indies consists of three separate archipelagos, each with unique origins and geologic composition.

Greater Antilles
'''[Two things for this section: 1) could you include a map? 2) could you include more about specific rock types, like is it granite, limestone, what type of limestone. There's not much of that level of geologic description here]'''The Greater Antilles is geologically the oldest of the three archipelagos and includes both the largest islands (Cuba, Jamaica, Hispaniola, and Puerto Rico) and the tallest mountains (Pico Duarte, Blue Mountain, Pic la Selle, Pico Turquino) in the Caribbean. The islands of the Greater Antilles are composed of strata of different geological ages including Precambrian fragmented remains of the North American Plate (older than 541 million years), Jurassic aged limestone (201.3-145 million years ago), as well as island arc deposits and oceanic crust from the Cretaceous (145-66 million years ago). The Greater Antilles have continuously been exposed since the start of the Paleocene or at least since the Middle Eocene (66-40 million years ago), but which areas were above sea level throughout the history of the islands remains unresolved. The Greater Antilles originated near the Isthmian region of present day Central America in the Late Cretaceous (commonly referred to as the Proto-Antilles), then drifted eastward arriving in their current location when colliding with the Bahama Platform ca. 56 million years ago in the late Paleocene. This collision caused subduction and volcanism in the Proto-Antillean area and likely resulted in continental uplift of the Bahama Platform and changes in sea level.

Lesser Antilles
The Lesser Antilles is a volcanic island arc rising along the leading edge of the Caribbean Plate due to the subduction of the Atlantic seafloor of the North American and South American plate s. The volcanic activity that formed these islands began at the end of volcanism [this might sound better as something like "the end of a period of volcanism"in the Greater Antilles during the Paleogene and continues today. The main arc of the Lesser Antilles runs north from the coast of Venezuela to the Anegada Passage, a strait separating them from the Greater Antilles. Major islands of the Lesser Antilles likely emerged less than 20 Ma, during the Miocene.

Lucayan Archipelago
The Lucayan Archipelago is a chain of barrier reefs and low islands of the Bahama Platform, a carbonate block fixed to the North American Plate [not clear here whether the carbonate block sentence section refers to the Lucayan Archipelago or the Bahama platform], and includes the Bahamas and the Turks and Caicos. The Bahama Platform is formed of marine sediments, and the emergent islands likely formed from deposits of wind-blown sediments accumulated during Pleistocene glacial periods.
