User:PJPark02/Nena (supercontinent)

Although everything in the article is related to the topic of the Nena Supercontinent, the information provided is partially inaccurate and misleading. There is currently a section on the Nuna Supercontinent that is mentioned which is loosely connected to the topic of the Nena supercontinent that may be slightly distracting from the main topic. All the information seems up to date, but there isn't much information on the page at all. The article currently contains information of the proposal of the possible Nena supercontinent and very general points about the assumptions made about the origins of it. The information is presented clearly, although it isn't fully accurate. The article links numerous other pages on wikipedia throughout.

The author has a neutral tone for the entirety of the article, partially due to the lack of volume of information and the general unambiguity of the topic. There aren't multiple viewpoints or any arguments included in the article due to the uncertainty and little information provided accessibility to the public.

The links in the source are actively working and they support the ideas mentioned throughout the article. Each fact is supported by an appropriate reliable source. The sources come from a paper written in 1990 (C.F. Gower and A.B. Ryan) and an article from ScienceDirect (Joseph G. Meert). These sources seem to be neutral.

Article Draft
Nena was the Early Proterozoic amalgamation of Baltica and Laurentia into a single "cratonic landmass" or minor supercontinent.

Name origins and supercontinent status
The name Nena, an acronym for Northern Europe–North America, was first proposed in 1990. Since then several similar Proterozoic supercontinents have been proposed, including Nuna and Arctica, that include other Archaean cratons, such as Siberia and East Antarctica. Because Nena did not include several Archaean cratons, including those in India and Australia, it is strictly speaking not a supercontinent. Nena was the core of Columbia, or Nuna, a larger supercontinent with several proposed configurations.

Assembly
Nena formed approximately 1,600 to 1,300 million years ago through continental drift of four major landmasses in the Penokean, Makkovikan, Ketilidian, and Svecofennian orogenies. In order of decreasing size, the landmasses were Laurentia (North American craton), Baltica (northwestern Eurasia), Siberia, and Antarctica.
