Columbia (conosciuto anche con il nome di Nuna, e più recentemente, Hudsonland o Hudsonia) è un ipotetico supercontinente che si pensa sia esistito approssimativamente tra 2,5 e 1,6 miliardi di anni fa nell'era proterozoica.Era costituito dai proto-cratoni degli antichi continenti Laurentia, Baltica, Scudo ucraino, Amazzonia, Australia e probabilmente anche della Siberia, del Nord della Cina. The youngest supercontinent is Pangea, which formed between 450 and 320 Ma and includes most of the existing continents (Figure 7.1).Pangea began to fragment about 185 Ma and is still dispersing today.

The existence of a pre-Rodinia Precambrian supercontinent, variously called Nuna or Columbia, has been widely speculated in the past decade, but the precise timing of its existence and its configuration have been uncertain due to the lack of unequivocal paleomagnetic and geological constraints.

Geologists have hypothesized that other super-continents have formed; Rodinia about one billion years ago, and Nuna about 800 million years before that. Previously, researchers had thought the new supercontinent would form in the mid-Atlantic region as Pangaea had or on the other side of the world in the current Pacific Ocean Rodinia was a Neoproterozoic supercontinent that assembled 1.1-0.9 billion years ago and broke up 750-633 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.

Information from the literature is augmented with the herein dated 1762 Ma (U-Pb) Januária dyke swarm from the São Fran-cisco Craton. A supercontinent is a single continental landmass made of all or most of the continental lithosphere at the time. There seems to be a cycle of supercontinents that form and split up every 400 or 500 million years, driven by plate tectonics. Scientists estimate that there was a cycle of at least seven supercontinents on Earth.

Supercontinent Nuna formed in two stages - Supercontinent

A supercontinent is a large area of land which has more than one continental core, or craton.They are formed by continental plates coming together. Continental plates have periodically collided and assembled in periods of orogeny (mountain-building) to form supercontinents.The cycle of supercontinents forming, breaking up, separating, and re-forming through plate tectonics happens about every. The new pole, only from Curaçá, for C/SF allows us to reconstruct the extended core of the supercontinent Nuna at 1.5 Ga.

  1. The paleo-position of the North China Craton (NCC) within the Supercontinent Nuna/Columbia is controversial.

Subsequent attempted breakup of Nuna may be represented by ca. 1.80 to 1.59 Ga consanguineous extension related sedimentation and magmatism in the southwestern Yangtze Block and northwestern Laurentia.
