Nuvvuagittuq Greenstone Belt Formation
c. 3.77 Billion years ago · Prehistoric
The Nuvvuagittuq Greenstone Belt formed approximately 3.77 billion years ago in northeastern Quebec, Canada, though some studies suggest origins as early as 4.3 billion years ago. This volcano-sedimentary sequence contains metamorphosed mafic volcanic rocks and chemical sedimentary rocks that likely represent ancient oceanic crust. Geochemical evidence indicates the rocks underwent hydrothermal alteration by seawater. The belt contains some of Earth's oldest known rocks and chemical signatures that may indicate early life or prebiotic processes.

Both preserve complementary records of early Earth's ocean chemistry and atmospheric conditions during the critical transition period when life was emerging, with Nuvvuagittuq representing slightly earlier conditions that evolved into those recorded at Isua Isua Greenstone Belt Banded Iron Formation
Nuvvuagittuq's chemical signatures indicating possible early life or prebiotic processes provide crucial comparative evidence for evaluating whether the Apex Chert structures are genuine biological fossils or abiotic formations, as both represent the earliest potential traces of life on Earth Apex Chert Microfossil Controversy
