The Isua Greenstone Belt is an Archean greenstone belt in southwestern Greenland. The belt is aged between and billion years. The belt contains . But the oldest known rocks on Earth are in Greenland, where a formation known as the Isua supracrustal belt (ISB) dates to between billion. – Ga Isua Greenstone Belt in West Greenland have revealed that the belt comprises a number of separate structural domains. Five such domains have.

The Isua greenstone belt (also known as Isua supracrustal belt) is part of the Archaean gneiss complex of West Greenland (Bridgwater et al. The Isua supracrustal belt of southern West Greenland (Fig. ) is the world's only locale in Eoarchean rocks where there are lacunae of sufficiently low strain. The mafic–ultramafic units of the ∼ Ga Isua supracrustal belt (ISB) in Greenland occur in a two-armed arcuate zone (eastern and western arms) and are.

The Isua supracrustal belt is the largest contiguous complex of Eoarchean By the early s, the main framework of West Greenland's geology was laid out. captured inside a billion-year-old rock in Greenland, may be the in the Isua Greenstone Belt in southwestern Greenland, a formation. Isua: geologic history of Earth: Formation of the secondary atmosphere: 8 billion years ago) at Isua in West Greenland, and thus this process must have been. The Isua Supracrustal Belt, Greenland, of Early Archean age (– Ga) represents the oldest crustal segment on Earth. Its complex.
