Abstract : Ascension Island is a geologic anomaly. It was formed by volcanism along the Mid-Atlantic Ridge about 7 million years ago, and that volcanism has continued as the oceanic plate moved westward away from the media valley of the ridge. Geologic mapping during this study has documented the distribution and age relationships of lithologies and structures. Chemical analysis of rocks samples and have allowed a quantitative classification of rock types. Potential for a geothermal discovery on Ascension Island is very high.
