The first supercontinent, called Columbia, or Nuna, existed from around 1.7 billion years ago to 1.45 billion years ago in the Precambrian period (4.6 billion to 541 million years ago).

Now a study published in the journal PNAS claims the formation process of these iron deposits was triggered by the breakup of the supercontinent Columbia, which caused massive tectonic activity.

they probably have nothing on the supercontinent of Pangaea, which took tens of millions of years to split up. But now, a unique fossil skull might readjust the timeline, with a strange creature ...

Next up in the supercontinent timeline is Kenorland, followed by Columbia (also known as Nuna), Rodinia, Panottia and Pangaea. In fact, according to Wilkins, plate tectonics will likely smoosh ...

Huge iron ore deposits in Western Australia's Hamersley Province formed when major tectonic events led to the breakup of supercontinent Columbia and to the amalgamation of Australia. When you ...

Two billion years ago, there was what some scientists call Columbia — the Siberia-centric first supercontinent. Tracking the paths of today’s continents through history takes some serious ...
