thread_title:  Copyright problem removed 

message: I removed the following sentence about Kenorland:
:It also formed a substantial part of Nena, the supercontinent associated with the Sudbury Basin Impact.
This had no source cited, and is untrue and confusing. The name Kenorland has two uses: one is the supercontinent or very large continent Kenorland (in this article). The other use is for a sub-section of Laurentia. The removed sentence refers to this latter, much smaller "Kenorland". It doesn't belong in this article, but it could be added to the Laurentia or perhaps the Canadian Shield article, with some rewording and a citation. In any case, the supercontinent Nena formed at least 200 million years after the supercontinent Kenorland broke apart. 2601:441:467F:9E00:F907:6112:FCDE:50 (talk) 18:51, 28 March 2020 (UTC)

replies: text: You're welcome. The Arctica article says "The core of Arctica was the Canadian Shield, which Williams et al. 1991 named Kenorland." Nena (supercontinent) says that Nena formed c. 1.9 billions years ago, while this article has Kenorland break up by 2.1 billion years ago. Therefore, the Kenorland supercontinent cannot be part of the Nena supercontinent (besides this contradicting the definition of "supercontinent"). 2601:441:467F:9E00:F907:6112:FCDE:50 (talk) 00:44, 31 March 2020 (UTC)
thread_title:  Error regarding Nena 

message: The maps look like original research to me. They're labeled "own work" and don't cite any sources used to draw them. The first map somewhat resembles one in Slabunov, Guo, Balagansky, and Lubnina 2017, but if that's one of the sources it isn't attributed. The second map doesn't resemble anything I'm seeing in a quick Google Search. (2017 publication is https://www.researchgate.net/publication/320423424_EARLY_PRECAMBRIAN_CRUSTAL_EVOLUTION_OF_THE_BELOMORIAN_AND_TRANS-NORTH_CHINA_OROGENS_AND_SUPERCONTINENTS_RECONSTRUCTION) 2601:441:467F:9E00:F907:6112:FCDE:50 (talk) 00:44, 31 March 2020 (UTC)
