Copyright University of Aberdeen 2013 ii Jolley & Passey C46-47-01 Abstract This study integrates the results of a field visits and subsequent laboratory analysis of volcanic and sedimentary rocks in the Malinstindur and Enni formations, Faroe Islands Basalt Group. Field mapping of stratigraphical sections allied to petrographic analysis has identified two competing shield volcano sourced flow fields in the Enni Formation. These shields are thought to be around 45 km in diameter, and were centred around Sandoy in the southwest, and around Svínoy and Fugloy in the northeast.
