Abstract

The comments by Nutman and Friend, and Hamilton, question our evidence for the presence of the Isua ophiolite. Their critical remarks are particularly directed at the veracity of our inferred sheeted-dike complex, the cogenicity of pillow lavas and dikes, and the nonexistence of modern equivalents. Here, we expand on our explanations in response to each of their comments to better justify our arguments and interpretation.
