Definition

The 35-km-long by up to 4-km-wide Isua supracrustal belt (ISB) lying within the Isukasia terrane, southern West Greenland (Fig. 1), consists of ca. 3,700 and 3,800 million years old (Ma) volcanic and sedimentary rocks that are among the oldest on the Earth. The ISB is the most significant and highly studied region for understanding early Earth chemistry and environments. This is because of its great antiquity and excellent exposures of a diverse range of rock types, including pillow basalts and banded iron formations (BIF).
