A) Major Hekla rhyolitic tephra at the base of the Rangá Fm, 1 km east of Galtalækur (right bank of the Ytri Rangá river, South Iceland). B) upper Kvíar rhyolite including about 2-5 mm pumice fragments (arrow), at Kvíar A site. C) “Þórsmörk Ignimbrite” from Tindafjell “two-magma” eruption, 358 ± 15 ka. D) multiple eruption of the Askja volcano, near East of the Ljósavatn (Preboral). E) multiple eruption of the Krafla volcano (upper Kvíar series, ∼127-123 ka) quarry of Daðastaðir (NE coast of Öxarfjörður). The age of this raised beach postdated the upper marine limit, evaluated in South Iceland to 127 ka (Van Vliet-Lanoë et al., 2018).
