Lopian orogeny

{{short description|Archean orogeny}}

The Lopian orogeny (also known as the Rebolian orogeny) was a mountain building event that affected the Baltic Shield during the Archean, between 2.9 and 2.6 billion years ago. The Kola-Belomorian gneiss and Karelian granitoid-greenstone terrane both formed during this time.{{cite journal |author=Gaal, G. & Gorbatschev, R. | year=1987|title=An Outline of the precambrian evolution of the baltic shield|journal=Precambrian Research| volume=35| pages=15–52| doi=10.1016/0301-9268(87)90044-1| bibcode=1987PreR...35...15G}}{{cite book |author=Goodwin, A. | year=1991|title=Precambrian Geology: The Dynamic Evolution of the Continental Crust|publisher=Academic Press|page=582| url=https://books.google.com/books?id=hkzgBAAAQBAJ&dq=lopian+orogeny&pg=PA582| isbn=9781483288550}}
