Isua Greenstone Belt

The Isua Greenstone Belt is a group of ancient rocks located in Greenland, dating back around 3.7 to 3.8 billion years. These rocks offer valuable insights into Earth's early crust and the planet's formation processes. Composed mainly of metamorphosed volcanic and sedimentary rocks, the belt preserves some of the oldest evidence of Earth's geological history. Its study helps scientists understand the conditions on early Earth, including the development of its first continents and possibly the origins of life, making it a significant site in the field of geology and planetary science.
