Abstract

While salt-influenced rift basins have been identified across the European Atlantic margin, the Irish Atlantic margin remains the exception despite salt being proven in several boreholes. Using an extensive seismic database coupled with data from exploration wells and shallow boreholes, this study maps the distribution and composition of salt layers and investigates their role in the structural evolution of the Slyne and Erris basins offshore west of Ireland. Two salt-prone intervals have been proven: The Upper Permian Zechstein Group and the Upper Triassic Uilleann Halite Member. The Zechstein Group is present throughout the Slyne and Erris ...  more
