Pannotia and Columbia supercontinent Columbia , along with landmasses before Columbia such as Ur continent Ur , were also surrounded by superoceans. As surface water moves unobstructed east to west in superoceans, it tends to warm from the exposure to sunlight so that the western edge of the ocean is warmer than the eastern. Additionally, seasonal changes in temperature, which would have been significantly more rapid inland, probably caused powerful monsoon s. In general, however, the mechanics of superoceans are not well understood. ref cite book last Martin first Ronald title One Long Experiment origdate 1998 04 08 publisher Columbia University Press isbn 0 231 10905 9 chapter Cycles and Secular Trends ref List of superoceans Expand list date August 2008 Mirovia Rodinia Pan African Ocean Pannotia Panthalassa Pangaea Mega Pacific Ocean Pangaea Ultima Super Atlantic Ocean Amasia continent Amasia Super Indian Ocean Amasia continent Amasia See also Portal box Environment Ecology Geography Weather br References references Category Historical oceans Category Plate tectonics tectonics stub palaeo geo stub es Superoc ano lv Superoke ns nl Superoceaan nn Superhav ru zh ...   more details

The CLGB is part of a much larger belt of Paleoproterozoic greenstones, a cover of metamorphism metamorphosed volcanic and sedimentary rocks that cover the Archean basement, the latter which is representative of the Archaean Karelian craton . Deposition of the cover sequence occurred between about 2.5 annum Ga and 1.8 Ga, thus it preserves information about History of Earth Earth s history from a period that encompass about 700 Ma. Thus, the CLGB records a prolonged and episodic history of rifting , sedimentation and magmatism before the collision and rift closure at about 1.9 Ga. The collision was related to the amalgamation of the supercontinent Columbia supercontinent Columbia .
