A petrochemical study of Esjufjöll volcano, eastern volcanic flank zone, Iceland
Fredrik Holm (BSc thesis)
Iceland has three volcanic flank zones which consist of three volcanic systems- Öræfajökull, Esjufjöll and Snæfell. As in Hawaii, the mildly alkaline rocks may indicate a pre- and post-shield building phase. This project evaluates the petrography and major and trace element composition of alkalai basalts and rhyolites of Esjufjöll volcano, in order to explore shield development through comparison with the eruptive products of Öræfajökull and Snæfell.
