Although textbooks give confident-looking representations of ancient landmasses with names like Laurasia, Gondwana, Rodinia, and Pangaea, these are sometimes based on conclusions that don't altogether hold up.

虽然教科书上好像很有把握地列出了古代的陆块,什么劳拉古陆呀,冈瓦纳大陆呀,罗迪尼亚大陆呀,泛大陆呀,但它们有时候是以不完全能成立的结论为基础的。

罗迪尼亚大陆

11亿年前的罗迪尼亚大陆重构。

罗迪尼亚大陆Rodinia,来自俄语 Родить,诞生;或 Родина,祖国)是古代地球曾经存在的超大陆,由当时几乎所有陆块合并而成。根据板块重构(Plate reconstruction),罗迪尼亚大陆存在于新元古代(11.5亿到7亿年前)。罗迪尼亚大陆是由存在于20到18亿年前的哥伦比亚大陆分裂后的陆块合并形成的。罗迪尼亚大陆和另一个超大陆盘古大陆已经是地球历史上广为人所接受的曾经存在的两个超大陆。

罗迪尼亚大陆在新元古代分裂,分裂的陆块之后在3到2.5亿年前合并成盘古大陆。相对于3亿年前的盘古大陆,目前对罗迪尼亚大陆的地球动力状态所知甚少。目前可以从古地磁学所提供的线索得知个别板块在罗迪尼亚大陆时代的纬度,但当时所在的经度则要靠现已散布在世界各地的相似地质特征来推测。

Rodinia 罗迪尼亚大陆

Proposed reconstruction of Rodinia for 750 Ma, with orogenic belts of 1.1 Ga age highlighted in green.  Red dots indicate 1.3–1.5 Ga A-type granites.[1]

Rodinia (from the Russian "Родина", ródina, meaning "The Motherland") is a Neoproterozoic supercontinent that was assembled 1.3–0.9 billion years ago and broke up 750–600 million years ago. Valentine & Moores 1970 were probably the first to recognise a Precambrian supercontinent, which they named 'Pangaea I'. It was renamed 'Rodinia' by McMenamin & McMenamin 1990 who also were the first to produce a reconstruction and propose a temporal framework for the supercontinent.
