South Greenland triple junction

{{Short description|Meeting point of three tectonic plates}}

The South Greenland triple junction was a geologic triple junction in the North Atlantic Ocean that divided the North American, Greenland and Eurasian plates. It existed during the Paleogene and consisted of the Mid-Labrador and Mid-Atlantic ridges. The triple junction became extinct when seafloor spreading along the Mid-Labrador Ridge ceased during the Eocene.{{cite journal | last1 = Oakey | first1 = Gordon N. | last2 = Stephenson | first2 = Randell | title = Crustal structure of the Innuitian region of Arctic Canada and Greenland from gravity modelling: implications for the Palaeogene Eurekan orogen | journal = Geophysical Journal International | volume = 173 | pages = 1041, 1045 | publisher = Royal Astronomical Society | year = 2008 | issn = 0956-540X }}
