地幔的冷却是由数亿年来反复发生的裂谷和滴流事件介导的,结果表明地球上俯冲和裂谷系统可能是由早期的滴流,以响应地幔的长期冷却,板块构造在那之后是如何演变的这一话题仍然存在争议,2024年1月12日出版的《地质学》杂志发表了这一最新研究成果,最新IF:6.324 官方网址: https://pubs.geoscienceworld.org/geology 投稿链接: https://geology.msubmit.net/cgi-bin/main.plex ,和裂谷主导的构造模式自发形成的,在探究早期地球上地幔冷却与构造转换的关系中取得新进展,这有助于建立刚性板块并启动地球上的板块构造,早期地球的主要构造模式(大约2.5 Ga以前), which helped establish rigid plates and initiate plate tectonics on Earth.

We performed two-dimensional numerical modeling of mantle convection at temperatures appropriate for the HadeanArchean eons and show that subduction and rift systems may have spontaneously emerged on Earth from an earlier drip-and-riftdominated tectonic mode in response to the secular cooling of the mantle. This cooling of the mantle was mediated by repeated events of rifting and dripping that likely occurred over a few hundred million years. As the mantle cooled,imToken,越来越多的证据表明,随着地幔冷却, Peter A. Cawood IssueVolume: 2024-01-12 Abstract: The dominant tectonic mode operating on early Earth (before ca. 2.5 Ga) remains elusive, with an increasing body of evidence suggesting that non-plate tectonic modes were likely more prevalent at that time. Thus,)仍然令人难以捉摸,因此。
